Know how to stop the unit and disengage the controls quickly.

2. Never allow children to operate the tiller. Never allow adults to operate the tiller without proper instruction.

3. Keep the area of operation clear of all persons, particularly children and pets.

4. Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and themselves.

Preparation

1. Thoroughly inspect the area where the tiller is to be used and remove all foreign objects.

2. Put the Wheels/Tines/PTO Drive Lever into NEUTRAL before starting the engine.

3. Do not operate the tiller without wearing adequate outer garments. Avoid loose garments or jewelry that could get caught in moving parts.

4. Do not operate the tiller when barefoot or wearing sandals, sneakers, or light footwear. Wear protective footwear that will improve footing on slippery surfaces.

5. Do not till near underground electric cables, telephone lines, pipes or hoses. If in doubt, contact your telephone or utility company.

6. Warning: Handle fuel with care; it is highly flammable and its vapors are explosive. Be sure to take the following precautions:

a. Store fuel in containers specifically designed for this purpose.

b. The gas cap shall never be removed or fuel added while the engine is running. Allow the engine to cool for several minutes before adding fuel.

c. Keep matches, cigarettes, cigars, pipes, open flames, and sparks away from the fuel tank and fuel container.

d. Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors.

Use a funnel or spout to prevent spillage.

e. Replace all fuel tank and container caps securely.

f. If fuel is spilled, do not attempt to start the engine, but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated.

7. Never make adjustments when engine is running (unless recommended by manufacturer).

Operation

1. Do not put hands or feet near or under rotating parts. Do not allow hands or any other part of the body or clothing near the rotating tines or near any other moving part. The tines begin to rotate forward once the engine starts, the Tines/PTO

Clutch Lever is in the ENGAGE position, the Forward Interlock Levers are squeezed closed and the Wheels/Tines/PTO Drive

Lever is shifted to FORWARD. The tines rotate in Reverse whether the Interlock

Levers are closed or open.

2. Exercise extreme caution when on or crossing gravel drives, walks, or roads.

Stay alert for hidden hazards or traffic. Do not carry passengers.

3. After striking a foreign object, stop the engine, remove the wire from the spark plug wire and prevent it from touching the spark plug. Thoroughly inspect the machine for any damage and repair the damage before restarting and operating the machine.

4. Exercise caution to avoid slipping or falling.

Section 1: Safety

8. Before cleaning, repairing, or inspecting, stop the engine and make certain all moving parts have stopped. Disconnect the spark plug wire and prevent it from touching the spark plug to prevent accidental starting.

9. The flap on the tine hood must be down when operating the tiller, unless using the Hiller/Furrower attachment.

10. Never use the tiller unless proper guards, plates, or other safety protective devices are in place.

11. Do not run engine in an enclosed area. Engine exhaust contains carbon monoxide gas, a deadly poison that is odorless, colorless, and tasteless.

12. Keep children and pets away.

13. Never operate the tiller under engine power if the Wheel Speed Lever is in the

FREEWHEEL position. In FREEWHEEL, the wheels will not hold the tiller back and the revolving tines could propel the tiller rapidly, possibly causing loss of control.

Always engage the Wheel Speed Lever in either FAST or SLOW position before starting the engine or engaging the tines with the Wheels/Tines/PTO Drive Lever.

14. Be aware that the tiller may unexpectedly bounce upward or jump forward if the tines should strike extremely hard packed soil, frozen ground, or buried obstacles like large stones, roots, or stumps. If in doubt about the tilling conditions, always use the following operating precautions to assist you in maintaining control of the tiller: a. Walk behind and to one side of the tiller, using one hand on the handlebars. Relax your arm, but use a secure hand grip.

b. Use shallower depth regulator settings, working gradually deeper with each pass.

c. Use slower wheel, tine and engine speeds.

d. Clear the tilling area of all large stones, roots and other debris. e. Avoid using downward pressure on handlebars. If need be, use slight upward pressure to keep the tines from digging too deeply.

f. Before contacting hard packed soil at the end of a row, reduce engine speed and lift handlebars to raise tines out of the soil.

g. In an emergency, stop tines and wheels by shifting the

Wheels/Tines/PTO Drive Lever into NEUTRAL. If you can not reach the lever or have lost control of the tiller, let go of the handlebars and all controls. Do not attempt to restrain the tiller.

15. Do not overload the tiller’s capacity by attempting to till too deeply at too fast a rate.

16. Never operate the tiller at high transport speeds on hard or slippery surfaces. Look behind and use care when backing up.

17. Do not operate the tiller on a slope that is too steep for safety. When on slopes, slow down and make sure you have good footing. Never permit the tiller to freewheel down slopes.

18. Never allow bystanders near the unit.

19. Only use attachments and accessories that are approved by the manufacturer of the tiller.

20. Use tiller attachments and accessories when recommended.

21. Never operate the tiller without good visibility or light.

22. Never operate the tiller if you are tired, or under the influence of alcohol, drugs or medication.

23. Operators shall not tamper with the engine-governor settings on the machine; the governor controls the maximum safe operating speed to protect the engine and all moving parts from damage caused by overspeed. Authorized service shall be sought if a problem exists.

24. Do not touch engine parts which may be hot from operation. Let parts cool down sufficiently.

25. POISON/DANGER—CAUSES

SEVERE BURNS. The battery on electric start models contains sulfuric acid. Avoid contact with skin, eyes or clothing. Keep out of reach of children.

Antidotes:

External– Flush immediately with lots of water.

Internal– Drink large quantities of water or milk. Follow with milk of magnesia, beaten eggs or vegetable oil. Call a doctor immediately.

Eyes– Flush with water for 15 minutes.

Get prompt medical attention.

26. DANGER– BATTERIES PRODUCE

EXPLOSIVE GASES. Keep sparks, flame or smoking materials away. Ventilate when charging battery or using in an enclosed space. Always wear safety goggles when working near battery.

27. Please remember: You can always stop the tines and wheels by releasing all controls, or by moving the ignition switch and/or throttle control lever on the engine to OFF or STOP.

28. To load or unload the tiller, see the instructions in Section 4 of this Manual.

29. Use extreme caution when backing or pulling the machine towards you.

30. Start the engine carefully according to instructions and with feet well away from the tines.

31. Never pick up or carry a machine while the engine is running.

32. When loading or unloading the tiller, always disengage tines and use slower wheel and engine throttle speeds. Use sturdy ramps wide and strong enough to easily support the tiller (280-to-325 lbs., depending on model) and operator.

Never go down ramps in FORWARD drive—the tiller could tip forward, exposing you to the tines (which should be disengaged). Always use REVERSE drive and back down ramps. To go up ramps, use FORWARD drive and follow the tiller.

33. The Forward Interlock Safety System should be tested for correct functioning every time the tiller or PTO power unit is used. See Section 4 in this Manual.

34. If using the optional Dozer Blade, either remove the tine attachment, or disengage the tines with the Tines/PTO

Clutch Lever. Revolving tines are dangerous.

Introduction

This section describes the location and function of the controls and features on your tiller. Refer to Section 4, Operation for detailed operating instructions.

Practice using these controls, with the engine shut off, until you completely understand the operation of the controls and feel confident with each of them.

IMPORTANT: Refer to the separate engine manufacturer’s Engine Owner’s Manual for information about the controls on the engine.

NOTE: All references to left, right, front and rear of the machine are based on a position behind the handlebars and facing forward.

PTO Attachments Feature

In addition to powerful tilling capability, you can quickly convert your machine into a PTO (Power Take-Off) Power Unit that is capable of towing or powering various TROY-BILT attachments.

You can access this capability by removing the tines attachment (powered by the PTO Power Unit). The PTO Power

Unit is then available for engine powered attachments, or for pulling or towing nonpowered attachments. See Section 4,

PTO Power Unit for detailed information on installing and operating TROY-BILT

PTO attachments.

Wheels/Tines/PTO Drive Lever

Use the Wheels/Tines/PTO Drive Lever (A,

Figure 3-1) to engage and disengage power to the transmission.

D

Figure 3-1:

A– Wheels/Tines/PTO Drive Lever E– Depth Regulator Lever

B– Forward Interlock Levers F– Handlebar Height Adjustment Lever

C– Wheel Speed Lever

D– Tines/PTO Clutch Lever

G– Engine Throttle Lever

This lever has three operating positions:

FORWARD, NEUTRAL and REVERSE.

FORWARD is engaged when the lever is moved down until the clutch roller (G,

Figure 3-2) engages into the detent position under the adjustment block (H,

Figure 3-2). You will definitely feel the lever engage into this position.

Use the FORWARD setting to move the wheels and tines forward, or to apply power to an optional PTO (Power Take

Off) attachment. (See also Forward

Interlock Levers.)

To stop the wheels, tines or any PTO attachment, move the lever to NEUTRAL by tapping the lever upwards (Figure

3-3) and releasing.

REVERSE is engaged when the lever is pushed (with an open palm) all the way up and held in that position (Figure 3-4).

Use this setting to move the wheels in reverse. To stop moving in reverse, release the lever; it automatically returns to the NEUTRAL position.

IMPORTANT: Do not operate the tines or any PTO attachment in REVERSE.

NEUTRAL is this control’s normal nonoperating position. The lever returns to

NEUTRAL when it is tapped out of the

FORWARD position or released from the

REVERSE position. NEUTRAL position is between FORWARD and REVERSE

(Figure 3-3). Use this setting to stop the wheels, tines or any PTO attachment.

IMPORTANT: Always shift to NEUTRAL before starting the engine or before engaging the wheels, tines or any PTO attachment.

Forward Interlock Levers

The Forward Interlock Levers (B,

Figure 3-1) are attached under each handlebar grip.

You must squeeze at least one of these interlock levers up against the handlebar grip whenever the Wheels/Tines/PTO

Drive Lever is engaged in FORWARD position.

11

Section 3: Features and Controls

Verify Position of Clutch Roller

When you shift between FORWARD,

NEUTRAL and REVERSE, the clutch roller at the base of the

Wheels/Tines/PTO Drive Lever should be positioned as shown in Figures 3-2,

3-3 and 3-4. Verify the position of the clutch roller as you shift the lever. If it is not positioned correctly, contact the

Factory or see your local authorized dealer.

If both Forward Interlock Levers are released before first returning the

Wheels/Tines/PTO Drive Lever to

NEUTRAL, the engine will stop.

IMPORTANT: The Forward Interlock

Levers are a safety control that stops the engine should you lose control while going forward and cannot shift into

NEUTRAL.

Wheel Speed Lever

Use the Wheel Speed Lever (C, Fig. 3-1) to select one of three operating positions:

SLOW, FAST or FREEWHEEL.

SLOW – Lever moved all the way down.

Most effective for normal tilling or for low-speed transport.

FAST – Lever moved all the way up.

Most effective for cultivating or for fastspeed transport.

FREEWHEEL – Lever in between SLOW and FAST (wheels will roll freely). Used when transporting the machine on level ground without engine power, and when using stationary PTO attachments.

IMPORTANT: To avoid transmission damage, always move Wheels/Tines/PTO

Drive Lever into NEUTRAL before shifting the Wheel Speed Lever.

IMPORTANT: When shifting into SLOW or FAST, gently roll the machine forward or backward to help fully engage the wheel gears. When engaged, the wheels will not turn unless the engine is running and the Wheels/Tines/PTO Drive Lever is engaged in FORWARD or REVERSE.

Tines/PTO Clutch Lever

Use this lever (D, Figure 3-1) to engage or disengage power from the transmission

PTO clutch to the tines or any PTO attachment. This control has two operating positions: ENGAGE and DISENGAGE.

ENGAGE – Lever moved into detent slot farthest from engine. Use this position to operate tines or other PTO attachments.

After shifting to ENGAGE, briefly operate machine in FORWARD to help fully engage the PTO clutch.

DISENGAGE – Lever moved into detent slot nearest engine. Use this position to disengage power to tines or other PTO attachments before transporting, loading, turning, or operating in reverse.

IMPORTANT: To avoid transmission damage, always move the Wheels/Tines/

PTO Drive Lever into NEUTRAL before shifting the Tines/PTO Clutch Lever.

Depth Regulator Lever

Use this lever (E, Figure 3-1) to regulate the tilling depth of the tines. This control also has a TRAVEL position, which enables transport with the tines off the ground.

To operate the lever, lift up on the handlebars, pull the Depth Regulator Lever straight back, and then slide it up or down to one of the eight detent height settings.

The eight detent positions offer a range of tine height settings. This enables you to select the height that is most effective for a particular condition. The top detent position is the TRAVEL setting. Use the second or third detent from the top for shallow tilling and cultivating. Use the other detents for deeper tilling and for power composting.

WARNING

To avoid personal injury, always place the tines in the TRAVEL position before starting the engine.

This prevents the tines from touching the ground until you are ready to begin tilling.

Handlebar Height Adjustment

Lever

Use this lever (F, Figure 3-1) to adjust the handlebars to one of two height settings.

1. To change the height, hold the handlebars with one hand and loosen the lever in a counterclockwise direction.

2. Move the handlebars to one of the two preset height settings.

3. Retighten the lever.

NOTE: You can swap the positions of the inside handlebar ratchets to change the two preset settings by approximately four inches higher or lower. See Section 2,

Step 2: Attach Handlebar for detailed assembly information.

Section 3: Features and Controls

WARNING

The tiller handlebars can be swung out o

30 to the right side for use only with the

PTO Chipper/Shredder attachment. This is done by loosening the mounting bolt on the handlebar base. Never operate your tiller or attachments, other than the

PTO Chipper/Shredder, with the handlebars in the right side position. Doing so could result in unsafe handling and personal injury.

Engine Controls

Refer to the engine manufacturer’s Engine

Owner’s Manual (included in the tiller literature package) to identify the controls on your engine.

IMPORTANT: An engine On/Off switch, a secondary throttle control, a choke lever and a fuel line shut-off control may be located on the engine. Refer to your

Engine Owner’s Manual for detailed information.

Engine Throttle Lever

Use the throttle lever (G, Figure 3-1) to adjust engine speed as well as to start and stop the engine.

Move the lever away from the STOP position before starting the engine.

Engine speeds are variable and range between the FAST and SLOW. Use the

STOP position to turn the engine off.

NOTE: A secondary throttle lever is located on the front of the 8HP and 10HP engines. A separate On/Off switch may also be available on the engine. (See

Engine Owner’s Manual for information.)

Keyswitch Starter

The keyswitch starter on electric start models (A, Figure 3-5) has three positions: OFF, RUN and START. Turn the key to START to start the engine.

Release the key and it will return to the

RUN position. Turn the key to OFF to

Starting Electric Start Engines with the Recoil Starter Rope

You may, at some point, have to start an electric start engine with the recoil starter rope. Before attempting to do so, perform the following applicable steps:

If you suspect the battery charge is weak, and there is no visible damage.

Disconnect cables from battery and clean both cable terminals, and the battery posts in accordance with the instructions provided in Section 5,

Battery Care and Maintenance.

15

Section 4: Operation

16

Reconnect the cables and securely tighten to battery posts. The engine will recharge the battery if the battery is still good.

If you suspect the batter is “dead”, or if the battery is damaged, disconnect, and remove it. Have it checked by a qualified technician.

If battery has been removed, wrap cable terminals at end of positive cable with electrical tape and secure the cable to the battery bracket. This will prevent electrical discharge.

Before pulling the recoil starter rope, turn the keyswitch to the RUN position.

Move the Throttle Lever away from

STOP position and set the choke as applicable. See Engine Owner’s Manual.

Cold Weather Operation

When temperatures fall below 40 o

F, do the following steps to protect your engine and transmission from damage:

4. Use the correct weight gear oil in PTO

Power Unit transmission.

5. Warm up the transmission gear oil as follows: With engine running, move

Wheel Speed Lever (Figure 4-2) to

FREEWHEEL (then block wheels so they can’t roll), put Tines/PTO Clutch Lever into DISENGAGE, then squeeze one of the Forward Interlock Levers and shift the Wheels/Tines/PTO Drive Lever to

FORWARD.

6. If wheels are frozen to the ground, melt ice with warm water.

Stopping the Engine and Tiller

1. To stop the wheels and tines, move the

Wheels/Tines/PTO Drive Lever into

NEUTRAL position and then release both

Forward Interlock Levers.

2. Move the engine Throttle Lever to the

STOP position. Then on electric start models, turn the key to OFF. Remove the key for safekeeping.

NOTE: The engine may have a separate

Throttle Control Lever and ON/OFF switch on the engine. These controls can also be used to stop the engine. See the Engine

Owner’s manual for information specific to your engine.

Operating the Tiller

When first practicing, keep the Tines/PTO

Clutch Lever in DISENGAGE position and the Wheel Speed Lever in SLOW position.

CAUTION

To avoid serious personal injury or damage to equipment:

• Always place Wheels/Tines/PTO Drive

Lever in NEUTRAL before starting engine, and before engaging wheels, tines or other PTO attachments.

• Be sure there are no obstacles behind you before moving in reverse.

• Wheels/Tines/PTO Drive Lever should automatically return to NEUTRAL when released from REVERSE position. If it does not, move lever to

NEUTRAL manually and discontinue use until you adjust the lever. See

Section 5, Checking and Adjusting

Reverse Drive System.

• No reverse motion should occur if

Wheels/Tines/PTO Drive Lever is not held up in REVERSE. See Section 5,

Checking and Adjusting Reverse

Drive System for adjustment steps.

Do not use tiller unless properly adjusted.

• Always return to NEUTRAL and let all motion stop before shifting to

FORWARD or REVERSE.

The following pages provide guidelines for using your tiller effectively and safely in various gardening applications. Be sure to read Tilling Tips & Techniques, in this Section, before you actually put the tines into the soil.

This is a traditional standard-rotating-tine

(SRT) tiller with forward rotating tines. It operates in a completely different manner than counter-rotating-tine (CRT) tillers, or from front-tine tillers.

Moving the Tiller Forward and Tilling

1. Start the engine and gradually increase engine speed to FAST (see Starting the

Engine, this Section).

DANGER

The Forward Interlock Safety System is designed for the operator’s safety. Do not disconnect or attempt to defeat the purpose of the system. If the system malfunctions, immediately contact your local authorized dealer or the

TROY-BILT Technical Service Department for assistance. Do not use the tiller or the PTO power unit until the

Forward Interlock Safety System is functioning properly. Always test the system before using the tiller or PTO power unit.

2. Test the Forward Interlock Safety

System. See Testing Forward Interlock

System, this Section.

WARNING

Keep away from rotating tines. Rotating tines will cause injury.

3. When practicing, set the Depth

Regulator Lever to Travel position.

Otherwise, set the Depth Regulator Lever to a desired depth.

4. Move Tines/PTO Clutch Lever to

ENGAGE position if you want the tines to turn. If practicing, leave in DISENGAGE.

IMPORTANT: Do not move Tines/PTO

Clutch Lever to ENGAGE unless

Wheels/Tines/PTO Drive Lever is in

NEUTRAL. Tiller damage may occur!

5. To move the tiller forward and engage the tines, squeeze and hold either Forward

Interlock Lever (Figure 4-3) against the handlebar grip, then move the

Wheels/Tines/PTO Drive Lever down to

FORWARD position.

Section 4: Operation

Figure 4-3: Moving tiller forward: squeeze one Forward Interlock Lever and then move Wheels/Tines/PTO

Drive Lever down to FORWARD.

6. When the tiller moves forward, relax and let the wheels power the tiller along while the tines dig. Walk behind and to one side of the tiller. Walk on the side that is not yet tilled (Figure 4-4). Use a firm grip on the handlebars but keep your arm relaxed.

IMPORTANT: Let the tiller move ahead at its own pace. Do not push it ahead—this reduces operator control and tilling efficiency. Do not push handlebars down in an attempt to dig deeper— this takes weight off the wheels, reduces traction, and causes the tines to try to propel the tiller.

Stopping Forward Motion and Tines

1. To stop forward motion, tap

Wheels/Tines/PTO Drive Lever upward into NEUTRAL. Then release the Forward

Interlock Levers. The wheels and tines will stop and the engine will continue running.

2. In an emergency, release all of the control levers. This stops forward motion and shuts-off the engine.

CAUTION

To Help Avoid Personal Injury or

Damage to Equipment:

• Be sure no obstacles are behind you before operating the tiller in REVERSE.

• Disengage the tines, reduce engine speed, and move the Wheel Speed

Lever to SLOW position before operating in REVERSE. Avoid using

FAST wheel speed until you are familiar with backing the tiller.

Figure 4-4: Guide tiller with one hand.

Moving the Tiller in Reverse

IMPORTANT: Do not till while in

REVERSE.

1. Shift the Tines/Wheels/PTO Drive Lever

(Figure 4-2) into NEUTRAL and move the

Wheel Speed Lever to the SLOW position.

2. Move Tines/PTO Clutch Lever (Figure

4-2) into DISENGAGE position.

3. Verify that the area behind you is clear.

4. Lift up the handlebars until the tines are off the ground, then shift the

Wheels/Tines/PTO Drive Lever all the way up and hold. You do not need to squeeze the Forward Interlock Levers to use reverse.

5. The unit immediately engages in reverse. Periodically check behind you while holding the handlebars up and the

Wheels/Tines/PTO Lever in its upper-most position.

Stopping Reverse Motion

Release the Wheels/Tines/PTO Drive

Lever– the lever automatically returns to the NEUTRAL position. This stops the wheels immediately. (The Forward

Interlock Levers will not stop REVERSE motion.)

To Stop the Engine

Move the engine Throttle Lever to the

STOP position. Then, on electric start models, turn key to OFF. Remove the key for safekeeping.

Making Turns

Turning the tiller is easy and just requires practice. First find the balance point between the engine and the tines by lifting up the handlebars (Figure 4-5). Once you find the balance point, then let the powered wheels do the turning as you push sideways on the handlebars in the direction of the turn. Practice the turning maneuver described here in a large open area. Once comfortable turning the tiller, you can then take it to the garden area.

1. At the end of a row, move the Wheels/

Tines/PTO Drive Lever (Figure 4-2) to

NEUTRAL position and reduce the engine speed.

2. Move the Tines/PTO Clutch Lever

(Figure 4-2) into the DISENGAGE position.

3. Resume forward operation, and lift handlebars until tines are off the ground

(Figure 4-5). Find the balance point between the engine and the tines. Then push the handlebars in the direction of the turn. Be very careful to keep feet and legs away from the tines (which should be dis-

engaged). Let the powered wheels do the hard work. The inside wheel will pivot in place while the outside wheel drives the tiller around in the direction of the turn.

Figure 4-5: Turning the tiller.

NOTE: Use REVERSE if necessary to turn in a limited space.

17

Section 4: Operation

4. When the turn is complete, shift to

NEUTRAL and lower the handlebars.

Move Tines/PTO Clutch Lever back to

ENGAGE position and resume forward operation.

Transporting The Tiller Around

Your Property

When the engine is running, the tiller’s powered wheels make moving the tiller to and from the garden easy. If the engine is not running set the Wheel Speed Lever to

FREEWHEEL position to roll the tiller to another location.

WARNING

To help avoid personal injury from revolving tines, always put the

Tines/PTO Clutch Lever in DISENGAGE position before transporting, loading, or unloading tiller.

DANGER

The Forward Interlock Safety System is designed for the operator’s safety. Do not disconnect or attempt to defeat the purpose of the system. If the system malfunctions, immediately contact your local authorized dealer or the

TROY-BILT Technical Service Department for assistance. Do not use the tiller or the PTO power unit until the

Forward Interlock Safety System is functioning properly. Always test the system before using the tiller or PTO power unit.

How to Check the Interlock System

The Forward Interlock System has an electro-mechanical design, and so is subject to normal wear and possible malfunction. Check the system for proper operation each time prior to using the tiller or PTO power unit.

1. Place the Tines/PTO Clutch Lever in

DISENGAGE position.

2. Move Depth Regulator Lever down all the way into the Travel setting.

3. If using engine power, move Wheel

Speed Lever to either SLOW or FAST, and use the Wheels/Tines/PTO Drive Lever to drive the wheels.

4. If the engine is stopped, move Wheel

Speed Lever to FREEWHEEL, and manually push tiller.

Testing the Forward

Interlock Safety System

The Forward Interlock Safety System is designed to shut the tiller engine off immediately if you lose control and cannot stop moving FORWARD by shifting the Wheels/Tines/PTO Drive Lever into NEUTRAL. When you release both

Forward Interlock Levers, they send ground to the ignition system thereby stopping the engine. Squeezing one or both levers up against the handlebars enables the ignition system; therefore, you must squeeze at least one lever whenever the Wheels/Tines/PTO Drive

Lever is engaged in FORWARD.

18

IMPORTANT: The interlock system also prevents the engine from starting if the

Wheels/Tines/PTO Drive Lever is engaged in FORWARD.

Figure 4-6: Plug and receptacle of

Forward Interlock Safety System must be securely connected.

To test the Forward Interlock System:

1. Move tiller outside to level ground.

Remove any obstacles.

2. Check that the Forward Interlock wire harness plug, at the bottom of the handlebars (Figure 4-6), is securely connected to the receptacle on the top, right side of the transmission.

3. Move Wheel Speed Lever (Figure 4-2) to SLOW position and move Tines/ PTO

Clutch Lever to DISENGAGE.

4. Start engine as described under

Starting and Stopping the Engine, in this section. Set engine throttle lever to

SLOW, and let engine warm up.

5. Squeeze and hold just one of the

Forward Interlock Levers against the handlebar grip while moving the Wheels/

Tines/ PTO Drive Lever down to

FORWARD (Figure 4-3). As the tiller moves forward, release the Forward Interlock Lever briefly. The engine should start to stall out if the interlock system is working properly. If it does start to stall, quickly squeeze the lever up against the handlebar grip, and then return the

Wheels/ Tines/ PTO Drive Lever to

NEUTRAL. Repeat this test to check that the engine begins to stall out when the other Forward Interlock Lever is released.

6. If the engine does not begin to shut off when either Forward Interlock lever is released, shut the engine off, remove the key (if electric start), and do not operate the tiller or PTO power unit until the system has been repaired and is functioning properly.

IMPORTANT: To avoid possible damage to the Forward Interlock Safety system, do not use high-pressure sprays near the wire harness receptacle or neutral plunger assembly.

Loading and Unloading the Tiller

The following provides information on tiller loading, unloading, and requirements before loading and unloading the tiller.

Read the following instructions carefully before attempting to load or unload your tiller.

Before Loading or Unloading the

Tiller

• Ramps must be strong enough to support the combined weight of the tiller and handlers. They should provide good traction to prevent slipping; they should have side rails to guide the tiller along the ramps; and they should have a locking device to secure them to the vehicle.

• Handlers should wear sturdy footwear that will help to prevent slipping.

Section 4: Operation

• Turn the vehicle’s engine off and apply its parking brake.

• Position the loading vehicle so that the ramp angle is as flat as possible (the less incline to the ramp, the better).

Loading the Tiller

1. Use loading ramps that are strong and wide enough to safely hold the weight of the tiller and the operator combined— your tiller weighs between 280 and 325 lbs.

2. Move the Tines/PTO Clutch Lever

(Figure 4-2) into DISENGAGE position.

3. Set the Depth Regulator lever (Figure

4-2) to the Travel position.

4. Move Wheel Speed Lever (Figure 4-2) into SLOW position and reduce the engine throttle speed.

5. Shift the Wheels/Tines/PTO Lever

(Figure 4-2) into FORWARD position and follow the tiller up the ramps (Figure 4-7).

Check the wheels as you move the tiller forward. Ensure that they move up the center of each ramp.

6. Prevent tiller from rolling in vehicle.

Leave Wheel Speed Lever in FAST or

SLOW position, chock wheels with blocks and tie down the tiller.

Figure 4-7: To go up ramps, use

FORWARD drive.

Unloading the Tiller

IMPORTANT: Never unload the tiller in

FORWARD drive. The tiller could tip forward and expose you to the tines

(which should be disengaged as instructed).

1. Use loading ramps that are strong and wide enough to safely hold the weight of the tiller and the operator combined— your tiller weighs between 280 and 325 lbs.

2. Move the Tines/PTO Clutch Lever

(Figure 4-2) to DISENGAGE position.

3. Set the Depth Regulator Lever (Figure

4-2) to the Travel position.

4. Move Wheel Speed Lever (Figure 4-2) to SLOW position and reduce the engine throttle speed.

IMPORTANT: Look behind you before you back down the ramp to ensure that all is clear. While descending, keep checking for obstacles behind you.

5. Move and hold the Wheels/Tines/PTO

Lever into REVERSE drive and back down the ramps (Figure 4-8). Check the wheels as you move the tiller backward. Ensure that they move down the center of each ramp.

Figure 4-8: To go down ramps, use

REVERSE drive.

Changing Speed Belts

Your tiller has two belt-driven speed ranges – HIGH RANGE and LOW RANGE

– you pick one or the other by deciding which set of pulley grooves to move the forward belt into. By moving the belt from one speed range into the other, in combination with the FAST and SLOW wheel speeds, you obtain a choice of four different forward wheel speeds and two different tine speeds.

WARNING

To help avoid serious personal injury, stop the engine, remove the ignition key, disconnect spark plug wire and move the wire away from the spark plug, and let engine and muffler cool down before changing belt speeds.

This change is done quickly and without tools (Figures 4-9 through 4-13).

Figure 4-9: Belt range positions.

When the tiller is moving in REVERSE, the wheels are powered by a rubber reverse disc, not by the belt. Therefore, you have only two reverse speeds SLOW and FAST, as set with the Wheel Speed Lever.

Table 4-1 shows the range of wheel and tine speeds available when using the two belt speed ranges and the FAST and

SLOW selections on the Wheel Speed

WARNING

The HIGH speed belt range position combined with a FAST wheel speed setting propels the tiller at the fastest pace. Reduce the engine throttle speed when starting out to help avoid personal injury or property damage if using this speed combination.

4. Go to right side of tiller and finish seating the belt.

5. Still holding the lever up in REVERSE position, and working from the left side of the tiller, move the belt from the lowerfront transmission groove to the lowerrear transmission groove.

6. Go to the right side of the tiller and finish seating the belt (Figure 4-13).

3. Kneel on left side of tiller. To create belt slack, reach over to right side of the pulleys and push in at the center of the belt with a finger. At the same time, use your left hand to work the belt part-way onto the lower-front transmission pulley groove (Figure 4-10).

Figure 4-10: Low range to high range.

Shows moving belt from lower-rear groove onto lower-front groove.

4. Go to the other side of the tiller to finish seating the belt onto the pulley groove.

5. Working from the left side of the tiller, work the belt as much as possible onto the top-front engine pulley groove (Figure

4-11).

6. Finish seating the belt from the right

side of the tiller.

IMPORTANT: Proper belt tension is important for good performance. See

Section 5, Drive Belt Maintenance for information on belt maintenance schedule and procedures.

NOTE: If extra belt slack is needed to move the belt, just raise the

Wheels/Tines/PTO Drive Lever up into

REVERSE. This lowers the engine pulley, and creates more slack.

Figure 4-11: Low range to high range. Shows moving belt from toprear groove onto top-front groove.

7. Check both sides of the high range pulley grooves to verify that the belt is properly seated.

Changing Belt From HIGH Range to

7. Check that the belt is fully seated in the pulley grooves. Check this from both sides of the tiller.

Choosing Wheel and Tine Speeds

Your tiller has four FORWARD wheel/tine speed combinations for handling a variety of tilling tasks and gardening jobs. Experiment with the tine depth, engine speed, and wheel/tine speed and determine the combination that provides the best results. Here are some tips:

1. Advance the throttle lever so the engine has sufficient power.

2. When tilling untilled or hard earth, do not set the Depth Regulator too deep. The tiller will buck and the engine will load down.

3. You will know your settings are ideal when the tines break-up the soil easily, the engine does not labor, and your progress is steady and smooth.

See Table 2, Wheel Speed and Belt Range

Selection Guide for recommendations.

Section 4: Operation

Doing so takes the weight off roots often grow close to the surface. If the powered wheels, causing them to needed, lift up on the handlebars slightly lose traction. Without the wheels to prevent the tines from digging too helping to hold the tiller back, the tines deeply.

(Sometimes, slight absorption and faster plant growth.

downward pressure on the handlebars will help get through a particularly tough section of sod or unbroken ground, but in most cases this won’t be necessary.)

Tilling depths

Avoid trying to dig too deeply too quickly, especially when busting sod or tilling soil that hasn’t been tilled for

some time. Use shallow depth settings

(only an inch or two deep) for the first passes through the garden area.

Avoid tilling wet, soggy soil

Tilling wet soil often results in large, hard clumps of soil that can interfere with planting. If time permits, wait a day or two after heavy rains to allow the soil to dry before tilling. Test the soil by squeezing it into a ball. If it compresses too easily, it is too wet to till.

WARNING

To help avoid personal injury, be aware that the tiller can unexpectedly bounce up or jump ahead and propel away from you if the tines strike hard or frozen ground, or buried obstacles like large stones, roots or stumps. Always use the following precautions to help maintain control of the tiller:

• Walk behind and to the side of the tiller. Use one hand on the handlebars, relaxing your arm but with a secure hand grip.

• Use shallow depth regulator settings.

Till gradually deeper.

• Use slower wheel, tine and engine speeds.

• Clear the tilling area of all large stones, roots and other debris.

• Do not put downward pressure on the handlebars. If needed, apply slight upward handlebar pressure to keep the tines from digging too deeply.

• Avoid contacting hard soil or sod at the end of a row – reduce engine speed and lift handlebars to raise tines out of the soil.

• In An Emergency, stop tines and wheels by moving Wheels/Tines/ PTO

Drive Lever to NEUTRAL. If you cannot reach the lever or have lost control, Let

Go Of The Handlebars and All Controls.

Section 4: Operation

Avoid making footprints

Tilling Tips & Techniques

When possible, walk on the untilled side of the unit to avoid making footprints in the freshly tilled soil (Figure 4-4). Footprints cause soil compaction that can hamper root penetration and contribute to soil erosion. They can also “plant” unwanted weed seeds back into the newly tilled soil.

Suggested tilling patterns

• When preparing a seedbed, go over the same path twice in the first row, then overlap one-half the tiller width on the rest of the passes (Figure 4-

14). When finished in one direction, make a second pass at a right angle as shown in Figure 4-15. Overlap each pass for best results (in very hard ground it may take three or four passes to thoroughly pulverize the soil).

IMPORTANT: When tilling on slopes, be sure the correct oil level is maintained in the engine (check every onehalf hour of operation). The incline of the slope will cause the oil to slant away from its normal level and this can starve engine parts of required lubrication.

Keep the engine oil level at the full point at all times!

A. Tilling up and down slopes:

• To keep soil erosion to a minimum, be sure to add enough organic matter to the soil so that it has good moistureholding texture and try to avoid leaving footprints or wheel marks.

WARNING

To avoid serious personal injury or damage to the equipment:

• Do not operate tiller on a slope too steep for safe operation. Go slowly on any slope. Make sure you have good footing.

• When tilling vertically, try to make the first pass uphill as the tiller digs more deeply going uphill than it does downhill. In soft soil or weeds, you may have to lift the handlebars slightly while going uphill. When going downhill, overlap the first pass by about one-half the width of the tiller.

HINT: For best results, use the HIGH belt range and SLOW wheel speed lever position. See Changing Speed Belts in this section for more information on changing to high range.

Figure 4-14

• If the garden size will not permit lengthwise and then crosswise tilling, then overlap the first passes by onehalf a tiller width, followed by successive passes at one-quarter width

(Figure 4-16).

• Wear footwear that increases stability and reduces slippage.

• Do not use FAST wheel speed position when on sloped ground.

Figure 4-15

• With planning, you can allow enough room between rows to cultivate

(Figure 4-17). Leave room for the hood width, plus enough extra room for future plant growth.

Tilling on slopes

If you must garden on sloping ground, please follow two very important guidelines:

• Do not shift the Wheel Speed Lever when heading up or down a slope. If lever is accidentally moved to FREE

WHEEL position, the tiller could roll out of control.

• To prevent engine damage due to oil starvation (on slopes,the engine is inclined and oil moves away from surfaces that need lubrication), be sure the correct oil level is maintained during all uphill/downhill tilling operations. Check the level of the oil in your engine after every onehalf hour of operation.

3

1

Figure 4-16

2

1. Till only on moderate slopes, never on steep inclines where footing is difficult (review safety rules in the

“Safety” Section of this Manual).

2. We recommend tilling up and down slopes rather than terracing. Tilling vertically on a slope allows maximum planting area and also leaves room for cultivating.

Figure 4-17

Section 4: Operation

Tilling Tips & Techniques

Clearing the tines

The tines have a self-clearing action which helps to eliminate most tangling of debris. However, occasionally dry grass, stringy stalks or tough vines may become tangled.

Follow these procedures to help avoid tangling and to clear the tines, if necessary.

WARNING

Before clearing the tines by hand, stop the engine, allow all moving parts to stop and disconnect the spark plug wire. Failure to follow this warning could result in personal injury.

Figure 4-18

B. Terrace Gardening:

• When a slope is too steep or too short for vertical tilling, it may be necessary to till across the slope and create terraced rows. Terraces are rows that are cut into the side of a slope, creating a narrow, but flat area on which to plant.

• On a long slope, you can make several terraces, one below the other.

• Terraces should be only 2-to-3 feet wide. Digging too far into the side of the slope will expose poor subsoil that is unproductive for plants.

• To create a terrace, start at the top of the slope and work down. Go back and forth across the first row as shown in

Figure 4-18.

• Each succeeding lower terrace is started by walking below the terrace you’re preparing. For added stability of the tiller, always keep the uphill wheel in the soft, newly tilled soil. Do not till the last 12" or more of the downhill outside edge of each terrace. This untilled strip helps prevents the terraces from breaking apart and washing downhill. It also provides a walking path between rows.

C. Tilling across slopes without terracing

• If vertical or terracing gardening aren’t practical for you, then you can till laterally across a slope. We don’t really recommend this method as it can create unsure footing and invites soil erosion.

• Study the terrain to make certain the slope is not too steep for safe tilling.

If possible, make terraced rows or till vertically.

• Move the belt into LOW belt range and the Wheel Speed Gear Lever to SLOW position. As in terrace gardening, start at the top of the slope and overlap the first pass by half the width of the tiller.

For added stability, keep the uphill wheel in the soft, newly tilled soil. Each succeeding terraced area is started by walking below the terrace you are preparing (Figure 4-19).

• To reduce tangling, set the Depth

Regulator deep enough to get maximum “chopping” action as the tines chop the material against the ground. Also, try to till under crop residues or cover crops while they are green, moist and tender.

• While power composting, try swaying the handlebars from side to side (about

6" to 12"). This “fishtailing” action often clears the tines of debris.

• It may be necessary to remove the debris by hand (a pocket knife will help you to cut away the material).

Figure 4-19: Make a terrace in just 4 or 5 passes with the tiller.

Section 4: Operation

POWER COMPOSTING

Tilling Tips & Techniques

Power composting means tilling under and burying in the soil all manner of organic matter such as crop residues, leaves, grass clippings and cover crops.

This material will decompose during the non-growing season and add important natural nutrients to the soil.

After tilling under crop residues, add more organic matter such as leaves, grass clippings and even kitchen scraps.

When tilled into the soil, this organic matter will decompose and add even more important nutrients to the soil.

After power composting, you may want to plant a “green manure” cover crop to protect the soil during the off-season.

WARNING

1. As you move forward into a row of stalks, aim the tiller so that the stalks go between the left wheel and the transmission case (Figure 4-19). Do not use the right wheel because damage could occur to the air cleaner, carburetor or throttle linkage.

When power composting, do not keep the Depth Regulator Lever at a deep setting if the tiller jumps or bucks.

Grow a crop of clover, alfalfa, buckwheat, peas, beans, rye grass, grain, or kale and then till it into the soil prior to the planting season.

If jumping or bucking occurs, move the Depth Regulator Lever down to one of the shallower settings and then slowly increase the tilling depth on later passes.

Failure to comply could result in loss of tiller control, property damage or personal injury.

Wide-Row Planting

The wide-row planting technique is spreading seeds anywhere from 10 inches to 2 feet wide or more. As a result, you can grow anywhere from 3 to

4 times (or more) produce in the same space that is normally set aside for an area that has narrow, single rows.

Figure 4-20: Tilling under corn stalks.

2. Each new pass should overlap the previous pass by one-half the width of the tiller.

Begin by composting crop residues such as leftover vines, stalks, stems and roots. Power compost these crop residues as soon as they finish bearing.

The sooner this is done, the better, as tender green matter is easier to till under. Use the deepest depth regulator setting possible without causing the engine to labor or the tiller to jump ahead.

Wide-row planting automatically shades the ground which keeps weed growth down and also holds moisture in the soil. And of course, harvesting is much easier – everything is right at hand to be picked. Preparing wide rows is easy — after you prepare the seedbed and mark off the rows with string, hand-broadcast the seeds as if seeding a lawn (not quite as much as lawn seed). Cover with soil and tamp the area firmly with a hoe.

3. Till as deeply as possible. Pull the

Depth Regulator all the way UP and engage the lowest notch for deep tilling.

Use either LOW or HIGH belt range and

SLOW wheel speed gear position.

Let the tilled-in stalks decompose for a week or so. Then till in the remaining residue as deep as possible.

Standing cornstalks of reasonable height can be power composted (Figure 4-20).

Pushing over (but not uprooting) cornstalks will often make it easier for your tiller to chop up the stalks. Keep the tines clear of excessive tangling by “fishtailing” or frequently using reverse.

Make several passes, then return a few days later to finish off any remaining stubble.

Tilling Under Corn

After corn is harvested, the stalks should be tilled into the soil while still green.

Dry plants are more difficult to till under, and the roots break loose too easily.

IMPORTANT: Do not pull the roots out by hand or cut the stalks before tilling.

Stalks that are firmly anchored by their roots are much easier for the tines to chop, cut, and work under.

Soil Enrichment Idea

Trench Composting — Trench composting is easy with the optional

Hiller-Furrower Attachment (Section

5). Dig a trench, put in all kinds of organic matter, and cover with soil.

Earthworms and microbes will break it down quickly.

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Tighten Bolts and Nuts

Check for loose or missing hardware every ten (10) operating hours. Failure to tighten or replace fasteners can cause poor performance, equipment damage or oil leakage. See your Parts Catalog for complete fastener descriptions.

Most hardware on your tiller is visible.

Pay particular attention to hardware shown in Figures 5-1, 5-2, 5-3 and 5-3A.

1. Check the transmission pulley mounting bolt (Figure 5-1). If the washer behind the bolt head is loose, the bolt needs tightening. To do this, first insert a punch or thick screwdriver into the hole next to the bolt and wedge the tool against the side of the motor mount casting. This immobilizes the pulley while you tighten the bolt.

2. Check jam nut on left side of neutral plunger assembly (Figure 5-2). If loose, immobilize bolt head with one wrench and use another wrench to tighten the nut.

3. Check the three rear bearing cap screws under the depth regulator mounting bracket (A, Figure 5-3). If any is loose, it can cause an oil leak or drive shaft end play.

4. Check the five bolts securing the tiller housing cover to the left side of the transmission (B in Figure 5-3). Gear oil can leak from a loose housing cover. To reach the bolts, remove the left side tine holder. See Bolo Tine Maintenance in this

Section for tine holder removal directions.

5. Check both swing-bolts (C, Figure 5-3) that connect the power unit transmission to the tine attachment. Both bolts should be checked every 2-1/2 hours of operation. If loose, wear can occur on the locating pin on the power unit, and cause enlargement of the locating hole in the tine attachment. Using a torque wrench, tighten these bolts to 70-to-80 ft.-lbs.

6. Check the locknut that fastens the shifting linkage to the eccentric shifting lever (D, Figure 5-3). Do not tighten the locknut against the eccentric lever. It should be very close to, but not touching the lever.

7. Check the four bolts and nuts securing left and right tine holders to the tine shaft

(Figure 5-3A).

IMPORTANT: Give screws or bolts that go into the transmission housing a coating of non-hardening gasket sealant to prevent gear oil from leaking.

Tiller Lubrication

Proper lubrication of the tiller’s mechanical parts is an essential part of good maintenance. Lubrication should be done after every ten (10) hours of operation.

Use ordinary motor oil (#30 weight or lighter) where oil is specified. Use a quality grease with a metal lubricant where grease is recommended (regular grease is acceptable). Do not over lubricate. If there is a build-up of dirt, remove the build-up and re-apply oil or grease.

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

30

IMPORTANT: Do not allow oil or grease to contact the pulleys, drive belt or reverse disc. This can cause the belt or disc to slip on the pulleys.

Lubricate the numbered areas in Figures

5-4 and 5-5, as follows:

1. Oil the wheel shaft between the wheel hubs and the transmission housing

(A, Figure 5-4).

2. Oil all pivoting and connecting points on the Wheels/Tines/PTO Drive Lever and the Wheel Speed Lever (B, Figure 5-4).

3. Grease the face of the belt adjustment block (C, Figure 5-4).

4. Oil the Depth Regulator Lever, including the spring in the mounting bracket (D, Figure 5-4).

5. Oil the full length of the throttle cable casing (E, Figure 5-4).

6. Oil threads on Handlebar Height Adjustment Lever (F, Figure 5-4).

8. Grease the zerk grease fitting located on the pivot point at the end of the Wheel

Speed Lever (H, Figure 5-4). If Wheel

Speed Lever has a grease fitting on pivot assembly, apply 2-to-3 strokes of multipurpose grease at beginning and end of tilling season.

9. Keep the PTO access area well-greased

(I, Figure 5-5). If the Tines/PTO Clutch

Lever becomes hard to move, squirt some oil into its access hole, and work it back and forth to disperse the oil.

Transmission Gear

Oil Maintenance

Checking for Oil Leaks

At 25-hour operation intervals, check the tiller for oil leaks. Inspect for oil accumulations on the tiller or the floor where it’s stored.

A

A small amount of oil seepage or wetness around a shaft opening or cover is no cause for alarm. But a heavy concentration of oil is more serious. You should tighten all bolts immediately, and replace any worn seals or gaskets.

G

It may be impossible to determine how much oil has been lost, so check the oil levels in the PTO transmission and the tine attachment before using the tiller again. Add any necessary gear oil.

Serious damage to the transmission components can result from operation when gear oil levels are low.

Figure 5-5: Use grease liberally in PTO access area.

If tilling during very hot weather, the gear oil may heat up and expand inside the transmissions. To allow for this oil expansion, both the power unit transmission and the tine attachment transmissions have oil relief vents (Figure 5-6).

Figure 5-6: Oil relief vent locations.

The vents allow small amounts of oil to seep out.

If a serious leak is discovered, please contact your authorized dealer or the

Factory Technical Service Department for service advice.

Checking Gear Oil Levels

Every 30 hours of operation, check the gear oil level in both the power unit transmission and the tine attachment transmission. Operating them while low on gear oil (even briefly) can cause serious damage to internal components.

Preparation

1. The transmissions must be cool, since hot gear oil expands and gives a false reading.

2. The power unit transmission and the tine attachment transmission must be connected when checking (or adding) gear oil.

Checking the Power Unit Oil Level

1. Move the tiller to level ground. Move the Depth Regulator up so the tines rest on the ground.

2. Use a 3/8" wrench to remove the oil level check plug on the left side of the transmission housing (Figure 5-7).

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Figure 5-7: Remove oil level check plug. Gear oil should seep out if the level is sufficient.

3. If the oil level is correct, oil will seep out of the check hole (allow extra time in cold weather). If it does, the level is fine and you should replace the check plug. If no oil seeps out, see Adding or Changing

Gear Oil.

Checking the Tine

Attachment Oil Level

IMPORTANT: Two different gear oil checking procedures for the tine attachment transmission are described next.

Use the first procedure if the dipstick in your tine attachment has only a ‘Check

Cold’ marking. Use the second procedure if the dipstick has both cold and hot markings at the end. First remove the dipstick from the tine attachment transmission (Figure 5-8) to see which type dipstick you have. Then replace the dipstick with markings on dipstick facing to rear.

➧

Figure 5-8: Checking gear oil level; markings on dipstick (tine attachment transmission) must face rear.

For Dipsticks With ‘Check Cold’ Marking

(Cold means 2 hours has passed since the tiller was used.)

1. Move the tiller to level ground.

2. Pull the Depth Regulator Lever back, then push it down all the way (to engage its top notch).

3. Place a sturdy support under the engine to prevent the tiller from tilting too far.

4. Now slide three pieces of 2" x 4" lumber underneath the drag bar– raising the drag bar about 4-1/2" above ground.

This elevation allows an accurate “cold” gear oil reading .

5. Wait two hours with tiller elevated

(allow more time if temperature is below

40 o

F).

6. Loosen and remove transmission dipstick (Fig. 5-8). Wipe it clean with a rag.

7. Hold dipstick so its markings face to rear of tiller. Lower it straight down into the sump hole to touch the drive shaft inside (Fig. 5-8). Don’t force or try to thread it back in; an incorrect reading will result.

8. Remove dipstick and check oil level. It should be anywhere within the crosshatched area or even slightly above the

Max marking. If correct, replace dipstick and remove the boards used as props.

9. If oil level was low, gear oil must be added before using the tiller. See Adding

or Changing Gear Oil next.

For Dipsticks With Hot/Cold Markings

1. Move the tiller to level ground.

2. Pull the Depth Regulator Lever back, then push it down all the way (to engage its top notch).

3. Place a sturdy support under the engine to prevent the tiller from tilting too far.

4. Cold reading (preferred method):

(Two hours has passed since the tiller was used.) Place a 2" x 4" board (on edge) under the drag bar– raising the tiller and drag bar about 3-1/2" above ground.

Hot reading: (Tiller was operated for more than 30 minutes within the past hour.) Do not use the wood prop to elevate the tiller.

5. Follow Steps 4, 5 and 6 given for the other dipstick type.

6. Remove dipstick and check level. It should be within or above the “Cold” range marking if taking a cold reading. If taking a hot reading, the level should be within or slightly above the “Hot” range.

7. If the level is incorrect, see Adding or

Changing Gear Oil.

Adding or Changing Gear Oil

For partial fill-ups (just a few ounces or less), use SAE 140, SAE 85W-140, or SAE

80W-90 weight gear oil with an API rating of GL-4 or GL-5. For full replacement, use SAE 140 or SAE 85W-140 gear oil with an API rating of GL-4 only. (At the factory, SAE 85W-140 weight gear oil is used.)

IMPORTANT: Do not use automatic transmission fluid or engine oil. They are too light in weight and will result in transmission damage.

The gear oil does not need to be changed.

Do so only if you know, or suspect, it is contaminated with dirt, sand or other foreign particles.

Gear oil is available at authorized dealers and most service stations, power equipment centers, or farm/heavy equipment outlets.

Capacities: Power unit transmission holds approximately 60 ozs.; Tine Attachment transmission holds approximately

12-1/2" ozs.

Failure to follow these instructions can result in serious personal injury or property damage.

32

Adding Gear Oil to the

PTO Power Unit Transmission

1. Do steps 1 and 2 of Checking the

Power Unit Oil Level on page 32.

2. Using a 3/4" wrench (or socket), remove the bolt securing the handlebar base to the top of the transmission (prop the handlebars first to prevent them from falling).

Then, unplug the Forward Interlock wire harness receptacle at the bottom of the handlebars. Set the handlebar base and bolt aside on a clean surface. The bolt hole in the top of the transmission is the gear oil fill hole (A, Figure 5-9).

3. Slowly pour gear oil through a clean funnel into the transmission. Stop when gear oil begins to flow from the oil level check hole on the left side of the transmission (B, Figure 5-7).

4. Reinstall the oil level check plug.

Tighten it securely.

5. Reinstall the handlebars using the mounting bolt previously removed. Align the handlebars so they point straight backwards, not at an angle. Then tighten the mounting bolt securely.

6. Reconnect the Forward Interlock wire harness to the receptacle. Be certain it’s secure.

7. Test operation of the Forward Interlock

Safety System. See Section 4 for a procedure.

Draining and Filling the

PTO Power Unit Transmission

1. Place a shallow pan under the transmission gear oil drain plug (B, Figure

5-9).

2. Remove the oil level check plug (Figure

5-7) with a 3/8" wrench. This vents the transmission for faster oil draining.

B

A

Figure 5-9: Gear oil fill hole (A) and gear oil drain location (B).

3. Using the 3/8" wrench, remove the drain plug (B, Figure 5-9). The gear oil will drain quite slowly since it is thick.

After about two quarts have drained, tilt the tiller forward so any oil at the rear of the transmission will drain out.

4. Clean the drain plug threads, put nonhardening gasket sealant on the threads, and reinstall plug.

5. Refill the transmission with the correct amount of gear oil before operating the tiller again. When oil seeps from the oil level check hole, the right amount of gear oil has been added. Replace all plugs.

3. Slowly add gear oil in the dipstick hole.

Add 1/2-ounce at a time to avoid overfilling. It takes about 12-1/2 ounces.

4. Take dipstick readings frequently. Stop when oil reaches “Cold” range marking on dipstick. Replace dipstick securely.

Draining and Filling the Tine

Attachment Transmission

1. The tine attachment transmission is not equipped with an oil drain plug. To drain just a small amount of gear oil, remove the dipstick and tilt the attachment forward (first uncoupling it from the

Power Unit).

2. For complete drainage, remove the leftside tine assembly (refer to Bolo Tine

Maintenance for instructions), then remove just one of the lower screws from the tiller housing cover (Figure 5-10). To speed drainage, remove the tine attachment dipstick to vent transmission.

➧

Adding Gear Oil to the Tine

Attachment Transmission

1. Select the right Depth Regulator Lever setting:

a. If filling an empty transmission, raise the Depth Regulator Lever so tines are on the ground.

b. If topping off the gear oil, move Depth

Regulator Lever down to engage its top notch.

2. Remove dipstick from tine attachment

(Figure 5-8).

Figure 5-10: Remove housing cover screw to drain tine attachment transmission gear oil.

NOTE: If you find a plastic washer on the cover screw you remove, discard the washer. There is no need to install a replacement washer.

3. Once all gear oil has drained, reinstall the housing cover screw securely (first coat its threads with non-hardening gasket sealant).

4. Be certain to refill the transmission with the correct amount of gear oil before operating the tiller again.

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Drive Belt Maintenance

Measuring and Adjusting

Drive Belt Tension

On a new tiller (or if a new belt is installed), the belt tension will probably need to be adjusted after the first two (2) hours of operation. Thereafter, check belt tension every ten (10) operating hours.

Maintaining the right tension is important to good tiller performance and long belt life. If too loose, the belt will slip on the pulleys, and be unable to deliver full power to the wheels and tines. A loose belt will also wear prematurely.

While checking belt tension, also inspect the belt for cuts, cracks, deterioration, etc. Don’t continue using a belt that isn’t in good shape. You’re sacrificing tiller performance by doing so.

Tips on keeping the drive belt in top condition include:

Always put the Wheels/Tines/PTO Drive

Lever in NEUTRAL when the tiller is not in use.

Keep tension adjusted correctly.

Don’t “speed shift” when moving the

Wheels/Tines/PTO Drive Lever between

FORWARD and REVERSE.

How to Measure Belt Tension

1. Before taking a measurement, be sure the linkages and pivot points on the

Wheels/Tines/PTO Drive Lever are clean and lubricated. If there is any binding, you won’t get true measurements. Also, you’ll need the belt adjustment tool you received with your new tiller (Figure

5-11).

2. Move the Wheels/Tines/PTO Drive

Lever fully down to the FORWARD position. The clutch roller at the bottom of the lever should be positioned underneath the belt adjustment block (Figure

5-12). Don’t let the clutch roller move during the next few steps. If it moves, you’ll get a false belt tension reading.

3. The belt tension is correct if the front of the clutch roller is 1/4"-to-5/16" away from the face of the upright bracket that holds the adjustment block in place

(Figure 5-12). To measure this distance:

a. Without moving the clutch roller, try inserting the 1/4"-thick, slotted end of the belt adjustment tool in between the roller and the upright bracket. (The flat edge of the tool must be facing the roller.) Refer to

Figure 5-13.

b. If only the slotted portion of the tool will fit, the belt tension is correct.

c. If the slotted part of the tool will not fit in, the belt is too loose.

d. If the full thickness (5/16") of the tool easily fits in, the belt is too tight.

4. If the belt tension is correct, move the

Wheels/Tines/PTO Drive Lever back to

NEUTRAL.

1/4"

5/16"

Figure 5-13: Insert slotted end of belt adjustment tool between roller and bracket, with the flat side of the slotted end facing the roller.

Belt Adjustment Tool

Figure 5-11: Use this belt adjustment tool to measure and adjust drive belt tension.

Figure 5-12: Shift into FORWARD and measure distance between roller and upright bracket using the belt adjustment tool.

How to Adjust Belt Tension

1. As described in the following steps, drive belt tension is adjusted by moving the adjustment block up or down.

Moving it down will tighten the belt; moving it up loosens the belt.

HINT: The distance the block moves approximately equals the distance the roller moves.

In most cases, the clutch roller will not have been very far out of position, so the adjustment block will only need to be moved slightly (up or down).

2. Move the Wheels/Tines/PTO Drive

Lever to NEUTRAL position. The clutch roller will come to rest anywhere on the face of the belt adjustment block, depending upon drive belt length and current belt tension adjustment.

33

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

3. Insert the belt adjustment tool through the hole in the side of the adjustment block, spacing the ends of the tool equally on both sides (Figure 5-14). Rotate the tool so the slotted end faces down.

34

Figure 5-14: With Wheels/Tines/PTO

Drive Lever in NEUTRAL, insert tool through hole in adjustment block.

4. Place the Wheels/Tines/PTO Drive

Lever in FORWARD position. The arms of the clutch control yoke will be resting on the belt adjustment tool and the clutch roller should be engaged slightly beneath the adjustment block (Figure 5-15).

Figure 5-15: With Drive Lever in

FORWARD position, clutch roller should be engaged slightly beneath the adjustment block.

5. Use one hand to hold the drive lever in

FORWARD while using a 9/16" wrench to loosen (don’t remove) the bolt at the back of the belt adjustment block (Figure 5-16).

The adjustment block should be free to move either up or down.

Figure 5-16: Hold Drive Lever while loosening bolt. Push lever down to tighten belt; pull up to loosen belt.

6. Push the drive lever down if the belt needs tightening. Pull the lever up if the belt needs to be loosened. Hold the drive lever in place and tighten the bolt in the adjustment block firmly.

7. Let go of the drive lever and remove the belt adjustment tool from the hole in the adjustment block.

8. Check the tension on the belt by following the previous instructions “How to Measure Belt Tension.”

NOTE: If the adjustment block is all the way down and the measurement between the clutch roller and the bracket is less than 1/4", then a new drive belt is needed.

Replacing the Drive Belt

Removing the Belt

1. Move Wheels/Tines/PTO Drive Lever to

NEUTRAL position.

2. While kneeling on the right side of the tiller, create slack in the belt by reaching over to the left side of the pulleys and pushing in on the center of the belt with your finger.

3. Use your right hand to move the belt down and away from the lower pulley, in the direction of the engine (Figure 5-17).

4. Push the belt upward to create slack in the belt (Figure 5-18).

Figure 5-17: First move belt off the lower pulley.

Push Belt UP

Figure 5-18: Push belt upward to create slack.

5. Lift the top half of the belt up and over the upper pulley and the rubber reverse disc, moving it in front of the reverse disc

(refer to Figure 5-19).

6. Push the Wheels/Tines/PTO Drive

Lever down into the FORWARD position.

This increases the distance between the upper and lower pulleys. Next, lift and pull the entire belt out between the pulleys

(Figure 5-20).

Replacing the Drive Belt

1. Place Wheels/Tines/PTO Drive Lever in

FORWARD position.

2. Squeeze the belt in the middle and insert one end in between the pulleys

(Figure 5-20).

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Figure 5-19: Move top half of belt over pulley and reverse disc.

Figure 5-20: Shift into FORWARD and remove the belt.

3. Push belt forward then down until it is looped over the lower pulley (Figure

5-18). Do not yet seat it in either of the lower pulley’s grooves.

HINT: A blunt object, like a ruler, can help you push the belt downward if needed.

4. Move the top half of the belt up and over the rubber reverse disc, but do not seat it in either of the grooves in the top pulley.

5. Place the Wheels/Tines/PTO Drive

Lever in NEUTRAL.

6. Move the top half of the belt into the

HIGH Range groove (groove closest to the engine) on the top pulley (Figure

5-21).

➦

➦

Figure 5-21: Seat belt in upper pulley, then in lower pulley (High

Wheels/Tines/PTO Drive Lever while moving the belt. Verify the belt is seated properly on the pulleys.

8. To move the belt to the LOW Range position, see Changing Belt Speeds in

Section 4.

9. After installing the belt, check and adjust for correct belt tension as explained previously.

Reverse Drive

System Maintenance

These instructions explain how to inspect, replace or adjust the various reverse drive components.

But first, here’s how the reverse drive system works: When you raise the

Wheels/Tines/PTO Drive Lever up in

REVERSE position, this lowers the rubberized reverse disc (it’s attached to the engine drive pulley) until this rotating disc contacts the transmission drive pulley.

The friction between the rotating reverse disc and the transmission pulley causes the transmission drive shaft to be powered in a counterclockwise direction

(as viewed from the operator’s position behind handlebars). The drive shaft then turns the wheels and tine shafts in a reverse direction.

Reverse Disc Inspection

The reverse disc is made of steel with a special, long-lasting rubber compound bonded to the disc rim. Since this is a wearing part, it should be inspected after every 30 operating hours.

1. Measure the width of the outside edge of the disc as shown in Figure 5-22.

Replace the disc before the rubber edge wears to a thickness of 1/8" or less.

Failure to do so could cause the steel underneath the rubber to damage the transmission pulley.

Figure 5-22: Measure the edge of the reverse disc for wear.

2. Look for big cracks or missing chunks of rubber from the disc. If so damaged, the disc should be replaced immediately.

IMPORTANT: Extend the life of the reverse disc by always pausing in

NEUTRAL before shifting between

FORWARD and REVERSE. Also – the reverse disc is not suited for continuous or sustained reverse operation. Use reverse sparingly.

35

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Replacing the Reverse Disc

Follow these steps to replace the reverse disc. (If your tiller has a Bumper Attachment mounted, it must be removed first.)

Removing the Reverse Disc

1. Move Wheels/Tines/PTO Drive Lever in

NEUTRAL position.

2. Wedge a 5/16"-thick board between top of engine pulley (avoid contacting reverse disc) and cast iron housing next to it.

This immobilizes pulley.

3. Use a 9/16" wrench to loosen the mounting bolt shown in Figure 5-23.

Remember to immobilize the pulley with the wood wedge while loosening the bolt.

If necessary, pry the disc from the pulley with the tip of a screwdriver. Back the bolt out as far as possible. Then angle the disc a little to remove it. Bring the bolt and lockwasher along with the disc.

and engine mount move down to press on the reverse adjustment bolt (Figure 5-

24). This action compresses the reverse spring and plunger assembly, requiring you to hold the lever up in REVERSE.

When you release the lever, the spring automatically pushes the lever back into

NEUTRAL position.

The spring and plunger assembly is designed to prevent the reverse disc from making contact with the transmission pulley until you shift into REVERSE.

When the lever is in NEUTRAL, the switch body on the bottom of the engine mount tab should be resting squarely on top of the reverse adjustment bolt (Figure 5-24).

The reverse adjustment bolt can be adjusted up or down to correct a number of reverse drive operating problems, as explained next.

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Adjusting Reverse Drive:

1. Place Wheels/Tines/PTO Drive Lever in

FORWARD position.

2. On left side of tiller, put a 1/2" wrench on the plunger retaining bolt and another

1/2" wrench on the jam nut next to it

(Figure 5-27). While holding the bolt steady, loosen the jam nut (counterclockwise) until it touches the bolt head.

7. Place a chalk or pencil mark on the top edge of the plunger retaining bolt. Now, while watching the mark, loosen the bolt

3/4-turn (Figure 5-29). Do not exceed a

3/4 turn (this would disengage the bolt from the locking groove in the side of the plunger).

Bolo Tine Maintenance

Checking Tines for Wear

Inspect the tines for wear or damage after every 30 operating hours. The rate of wear depends upon hours of use and soil conditions. With use, the tines get shorter, narrower and more pointed

(Figure 5-30). If badly worn, they lose the ability to till deeply.

Figure 5-27: Hold bolt steady while loosening or tightening jam nut.

3. Turn the bolt in until it tightens against the plunger inside the spring. The bolt must be tight to prevent plunger from turning – but be careful not to overtighten and break the bolt.

4. Place a 7/8" wrench on the head of the reverse adjustment bolt and a 9/16" wrench on the jam nut below it (Figure 5-

28). Hold the bolt steady while loosening the jam nut three or four turns.

5. Move the Wheels/Tines/PTO Drive

Lever to NEUTRAL. The switch body on the bottom of the engine mount tab

(Figure 5-24) should be resting squarely on top of the reverse adjustment bolt, and the reverse disc should be at least 3/16" away from the transmission drive pulley.

If the reverse disc is any closer than this, raise the reverse adjustment bolt (turn it counterclockwise).

6. Check that reverse disc is at least 3/16" away from transmission drive pulley.

Then hold reverse adjustment bolt steady with one wrench while tightening jam nut with a second wrench (Figure 5-28).

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Single Tine Replacement

WARNING

The tines or tine hood edges may be sharp. Wear thick gloves to protect your hands from cuts or scrapes.

1. Move the Wheels/Tines/PTO Drive

Lever to NEUTRAL, the Wheel Speed

Lever to either FAST or SLOW position, and the Tines/PTO Clutch Lever to

ENGAGE.

2. Gently tilt the tiller forward until the engine rests on the ground.

3. Raise the hood flap at the back of the tiller and tie it up with string.

4. Before removing a tine, note in which direction the bent tip points. The new tine must be installed in the same direction.

5. Use two 9/16" wrenches to remove the two bolts and nuts securing the tine to the tine holder plate (Figure 5-32). Use penetrating oil on the hardware if it is rusted or hard to remove.

Removing and Replacing A Tine

Holder Assembly

WARNING

• The tines or tine hood edges may be sharp. Wear thick gloves to protect your hands.

• Wear safety goggles to protect your eyes. When loosening hardware, do not hit a wrench with a metal tool– this could shatter the tool or wrench, sending metal particles into your eyes.

3. Remove the two bolts and nuts securing each holder (Figure 5-33).

4. Use a soft mallet to drive the holder off the tine shaft. (Use a heavy hammer and block of wood to knock off the immobilized tine holder.)

5. When the holder is off, clean all dirt and debris from the shaft and the holder.

Apply fresh grease to the tine shaft.

Replacing Tines Holder Assembly

1. Replace the holder so the sharp tine edges face forward (toward front of tiller).

Tap tine holder back on the tine shaft.

2. Grease the threads on the mounting bolt(s). Install and tighten the bolt(s) securely.

The 16 Bolo Tines are mounted eight per side on left-side and right-side tine holders. Here’s how to replace the tines and holders as assemblies.

Removing Tine Holder Assembly

1. Follow steps 1-through-3 in Single

Tine Replacement above.

2. Identify the tine holders as left-side and right-side holders – they must be replaced on the same side from which they were removed. Use a piece of chalk

or a grease pencil to mark them L and R.

38

Tine Shaft

Figure 5-32: Removing a single tine requires taking off two bolts and two nuts.

6. Mount the new tine exactly the way the old tine was positioned. (The sharp edge of the tine, which enters the soil first, must face forward when above the tine shaft.)

Replace the bolts and nuts and tighten them securely.

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Tine Shaft Maintenance

After every 10 operating hours, remove the left- and right-side Bolo Tine holders and clear away dirt and debris that have accumulated on the tine shaft or inside the tine holders. Please follow this maintenance recommendation, as debris can cause premature wear to the tine shaft and its oil seals. Refer to the previous tine holder removal instructions. After cleaning away any debris and removing old grease from the tine shaft, apply fresh grease to the tine shaft.

Tire and Wheel Maintenance

Check tire air pressure every 30 operating hours. The recommended pressure for tilling is 10-to-20 psi (pounds per square inch). Both tires should be inflated equally. (Unequal pressure can cause the tiller to pull to one side.)

Removing the Wheels

Each wheel is secured by a roll (spirol) pin that passes through the wheel hub and the wheel shaft. Drive the roll pin out to remove a wheel.

1. Prop the transmission up with a sturdy block to raise the wheel you want to remove off the ground.

2. Move the Wheel Speed Lever to either

SLOW or FAST position to prevent the wheels from turning.

3. Use a 5/16" drift pin (or a blunt point

16-penny nail) to drive the roll pin free.

WARNING

Wear safety goggles when driving the roll pin into or from the wheel hub to protect your eyes from the possibility of flying metal particles.

It is recommended that you change the oil every ten (10) operating hours and even sooner when operating in extremely dirty or dusty conditions. Refer to the separate

Engine Owner’s Manual for detailed service instructions.

Air Cleaner Maintenance

The engine is equipped with a dual element air cleaner that filters the air twice before it enters the carburetor to mix with the fuel.

The engine air cleaner filters dirt and dust out of the air before it enters the carburetor. Operating the engine with a dirty, clogged air filter can cause poor performance and damage to the engine. Never operate the engine without the air cleaner installed. Inspect and service the air cleaner more often if operating in very dusty or dirty conditions.

It is critical that the filters be kept clean and properly installed at all times. See the location of the air cleaner assembly on your engine by referring to Figure 5-39 or

Figure 5-40.

Refer to the engine manufacturer’s literature supplied with your tiller for complete air cleaner service and maintenance information.

Throttle Cable Maintenance

The throttle lever settings are factoryadjusted, so unnecessary adjustments should not be made. However, if the engine does not start or stop, or respond immediately to various throttle lever settings, then adjustments may be necessary. Please refer to the engine manufacturer literature supplied with your tiller for specific adjustment instructions.

Spark Plug Maintenance

The spark plug must be in good condition for proper engine operation. Remove and inspect the plug every 50 operating hours or annually, whichever occurs first.

The correct electrode gap is .030". Check the gap with a feeler gauge. Do not use a spark plug if the porcelain is cracked, the electrodes are pitted or burned, or if other visible damage is present.

NOTE: Do not wire brush or sandblast the spark plug to clean it – loose particles can enter the engine, causing damage!

To replace the plug, first tighten it securely by hand, then use a spark plug wrench to tighten the plug an extra 1/4 turn.

Battery Care and Maintenance

The battery is sealed and is maintenencefree. Acid levels cannot be checked.

• Always keep the battery cables and terminals clean and free of corrosive build-up.

• After cleaning the battery and terminals, apply a light coat of petroleum jelly or grease to the terminals and cover both terminals with the rubber boots.

WARNING

When removing the battery, always disconnect the negative (-) cable first followed by the positive (+) cable. Reverse this procedure when reinstalling the battery.

Engine Oil Maintenance

Check the engine oil level before starting the engine each day and after each 5 hours of continuous operation. Running the engine when it is low on oil will quickly ruin the engine.

Ignition System Maintenance

Your engine is equipped with electronic ignition. It does not have a condenser or points, so there is no need to perform any regular tune-up maintenance on this system other than adjusting or replacing the spark plug.

39

40

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Storing Your Tiller

When your tiller won’t be used during the off-season, prepare it for storage with the following steps:

1. Clean the tiller and engine.

2. Do routine tiller lubrication and check for loose hardware.

3. Protect the engine from deterioration or damage by referring to the engine storage instructions in your engine manual literature.

4. When engine is still warm, drain oil from engine crankcase. Refill with fresh motor oil.

5. Protect internal cylinder against rust by removing spark plug and pouring one ounce of clean engine oil into spark plug hole. Then slowly pull out recoil start rope 2 or 3 times to distribute oil internally. Replace spark plug, but do not reconnect plug wire. Pull rope until resistance is felt — let rope rewind.

6. Charge battery (electric start option).

Store battery in cool, dry location.

7. Move Wheels/Tines/PTO Drive Lever to

NEUTRAL position. Keep tiller in a clean, dry area.

8. Never store tiller with fuel in fuel tank in an enclosed area where gas fumes could reach an open flame or spark, or where ignition sources are present (space heaters, hot water heaters, furnaces, etc.).

Inspecting Forward Interlock

Wiring System

Check the Forward Interlock wiring system every ten (10) operating hours, for tight connections and to see that the insulation on the wires is unbroken (to prevent the system from shorting out).

1. Check insulated wire harness from lower ends of handlebars to wire harness connector on top, right side of transmission cover. Be sure connector is secure.

2. Check insulated tubing from connector to cast iron motor mount/belt shroud.

3. Check the wire leading from the tubing over to the switch assembly mounted on top of the tab on the cast iron motor mount–belt shroud. Also check the second wire that leads to the throttle cable mounting bracket on the right side, forward portion of the engine.

Testing the Forward

Interlock Wiring System

The wiring circuit for the Forward

Interlock Safety System is designed to ground out the engine’s ignition system.

There are three switches in the circuit which, when open, let the engine run.

One switch is on the neutral plunger tab of the cast iron motor mount. This switch is open whenever the Wheels/Tines/PTO

Drive Lever is in NEUTRAL or REVERSE positions. The other two switches are located inside the handlebars, directly above the two Forward Interlock Levers.

The switches are wired so when squeezed

(open) the engine will run. There is a fourth switch located in the wiring harness connector on the top, right side of the transmission cover. It warns you if the connection is not mated by not letting the engine run while the Wheels/Tines/PTO

Drive Lever is in FORWARD.

1. A broken or disconnected wire could let the engine run without you having to press one of the Forward Interlock Levers.

2. A bare wire touching tiller or engine metal could ground out the engine’s ignition.

3. A switch that has failed allows the engine to run. Or it may prevent the engine from running.

Refer to the Troubleshooting section if your Forward Interlock Safety System is not operating correctly.

Figure 5-43: Check connecting rod, shifting linkage and eccentric lever.

• Lubricate eccentric lever at rear of power unit transmission (Figure 5-43). If rust is present, use penetrating oil and work eccentric lever back and forth by hand.

• Lubricate linkage to Wheel Speed Lever to eccentric lever (Figure 5-43).

• Clutch inside transmission may be binding.

Disconnect linkage from eccentric lever and work eccentric lever by hand. If difficult or impossible to move, it may be due to a damaged keyway on the wheel shaft.

Contact Technical Service Department.

• Lubricate washers and castle nut on pivot of lever. If necessary, remove roll pin and back nut off 1/6th turn. Replace roll pin and test the movement.

• Apply grease to zerk fitting (if so equipped) with grease gun until grease appears around washers.

B. Lever shifts into FAST wheel gear, but not into SLOW wheel gear–

• Connecting rod at end of lever might be backwards, or bent in toward transmission housing and hitting it. Other shifting linkage might be bent. Straighten or replace linkage

(Figure 5-43).

• Clutch inside transmission may be binding

(Problem 2-A).

C. Lever moves freely, but won’t shift in or out of gear–

• Eccentric shifting pin inside transmission may be broken (rare) or worn. Disconnect linkage from eccentric lever and try moving eccentric lever by hand (Figure 5-43). If lever moves easily, contact the Technical

Service Department.

3 Wheels and Tines Won’t Turn:

• Review operation of controls (Sect. 3 & 4).

• Check condition and adjustment of drive belt and reverse disc (Sect. 5).

• Mounting bolt for transmission drive pulley may be loose. (See Figure 5-1). If so, drive belt or reverse disc will turn pulley, but pulley won’t turn main drive shaft.

• Worm gears that drive wheel and tiller shafts may be worn.

4 Wheels Turn, But Tines Won’t:

• Tines/PTO Clutch Lever must be in ENGAGE position (Sect. 3).

Appendix B: Attachments & Accessories

Troy-Bilt

®

PTO Log Splitter

290-258-081

The Troy-Bilt ® PTO Log Splitter provides you with a convenient and easy means of splitting about a half a cord of wood per hour when working alone. When connected to the PTO Power Unit, the tiller’s engine runs the splitter’s hydraulic pump, providing you with 13 tons of steady, unhurried and predictable splitting force.

As an added benefit, the power-driven mobility provided by the PTO Power Unit allows you to move the splitter to and from your wood pile, over to a neighbor’s place, or along the woodpile to a fresh supply of logs.

Features include a 15 second splitting cycle; can handle log sizes up to 26" long; a two-stage hydraulic pump that automatically shifts into low gear to provide fourtimes greater pressure when needed; slim-cut wedge design for splitting green, stringy wood; and an auto-control valve for automatic return stroke.

Dozer/Snow Blade Attachment

290-259-081

In the winter, moves up to one foot of light snow (or 6"-to-8" of heavy snow); at other times use it to move or spread sand, gravel, loose dirt, grain, sawdust, etc. Attaches easily to the front of the

Wrap-Around Bumper Guard. Set the blade to several angles. Weighs 41-lbs.; measures 15" x 32".

Row Marker Attachment

290-257-081

Do you like very straight, even, neat rows in your garden? If so, the Row Marker is a must attachment. Hooks quickly to the

Hiller/Furrower attachment– eliminates the need for string, stakes, measuring tape, etc. You’ll like the straight rows it helps you make if you lay out furrows, dig compost trenches, or make raised beds.

The Row Marker extends from 28"-to-

49 3 ⁄

4

", letting you vary the width between rows to suit the crop you’re planting.

V-Sweep Cultivator

290-260-081

The V-Sweep Cultivator is a specialized tool designed for between-row crop cultivation. Instead of stirring the soil, it slices through just below the surface to eliminate practically any weeds in its path.

The Sweep mounts easily to the optional

Tow Hitch Attachment at the rear of the

PTO Power Unit. The blade is made of high carbon, heat treated steel and measures 2" wide (overall wing span is

20").

The unique way the Sweep works, skimming along just underneath the soil’s surface without turning the soil over, makes this the ideal tool for use in dry, dusty conditions where it is important to keep soil disturbance to a minimum.

And, because of its 20" wide cutting path, it does an effective cultivation job at a fast speed.

The Sweep’s natural shallow cultivation helps to prevent weed seeds from being brought to the soil’s surface. This shallow cultivation feature also means there’s less chance of damaging the roots of your vegetables. For deeper or more shallow cultivating, the blade depth can be changed with a simple adjustment..

Wheel Weights

290-266-081

Help increase traction by putting extra weight directly on the wheels. They reduce bucking and jumping when deeptilling in heavy soil. They’re shipped empty– fill them with material like concrete, sand, gravel, etc. They bolt directly to the tiller wheels.

Wrap-Around Bumper Guard

290-255-081

Order this Bumper Guard by itself or receive it as one of the components if you order the combination Dozer/ Snow Blade attachment. Protects the engine from damage by wrapping around and protecting many of the engine components. 1" diameter, high-strength steel tubing.

Hiller/Furrower Attachment

290-250-081

The most popular attachment because it does so many jobs. Mounts to the rear of the depth regulator bracket. Furrower blade easily makes plant rows, trenches, ditches to 8" deep. When hiller wings are attached to furrower blade, attachment makes hilled rows and raised bed gardens. Converts from a furrower to a hiller and back again, in seconds, without tools.

Any implied warranties, including any implied warranty of merchantability or fitness for a particular purpose, shall be limited in duration to the period of ownership by the original purchaser (and a maximum of 90 days from the date of sale if the tiller is purchased for commercial or other non-residential use).
