PROTECTION FOR CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children.

Children are often attracted to the machine and the mowing activity. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine.

Never assume that children will remain where you last saw them.

1.

KEEP children out of the mowing area and under the watchful care of a responsible adult other than the operator.

2.

DO NOT allow children in yard when machine is operated

(even with the blade OFF).

3.

DO NOT allow children or others to ride on machine, attachments or towed equipment (even with the blades OFF). They

may fall and be seriously injured.

4.

DO NOT allow pre-teenage children to operate machine.

5.

ALLOW only responsible adults & teenagers with mature judgment under close adult supervision to operate machine.

6.

DO NOT operate blades in reverse. STOP BLADES. LOOK

and SEE behind and down for children, pets and hazards before and while backing.

7.

USE EXTRA CARE when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

PROTECTION AGAINST TIPOVERS

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death.

All slopes require extra CAUTION.

If you cannot back up the slope or if you feel uneasy on the slope, DO

NOT mow it. Use extra care with grass catchers or other attachments; these affect the handling and the stability of the machine.

1.

DO NOT operate machine on slopes exceeding 15 degrees

(27% grade).

2.

Exercise EXTREME CAUTION on slopes above 10 degrees

(18% grade). Turn blades OFF when traveling uphill. Use a slow speed and avoid sudden or sharp turns.

3.

DO NOT operate machine back and forth across face of slopes. Operate up and down. Practice on slopes with blades off.

4.

AVOID starting, stopping or turning on slopes. If machine stops going uphill or tires lose traction, turn blades OFF and back slowly straight down the slope.

PROTECTION AGAINST TIPOVERS

(Continued From Previous Column)

5.

STAY ALERT for holes and other hidden hazards. Tall grass

can hide obstacles. Keep away from ditches, washouts, cul-

verts, fences and protruding objects.

6.

KEEP A SAFE DISTANCE (at least 3 feet) away from edge of ditches and other drop offs. The machine could turn over if an edge caves in.

7.

Features& Controls

CONTROL FUNCTIONS

The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing require the combined use of several controls appfied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section.

Motion Control Levers

These levers control the ground speed and direction of the rider. The left lever controls the left rear drive wheel and the right controls the right rear drive wheel.

Moving a lever forward increases the FORWARD speed of the associated wheel, and pulling back on a lever increases the REVERSE speed.

The further a lever is moved away from the neutral position the faster the drive wheel will turn.

See the OPERATION section for steering instructions.

Engine Speed Control

The engine speed control controls engine speed. Move

the engine speed control forward to increase engine speed and back to decrease engine speed. Always operate at FULL engine speed.

Choke

Close the choke for cold starting. Open the choke once the engine starts. A warm engine may not require choking. Move the lever forward to close the choke. Move the lever back to open the choke.

Features& Controls

Ignition Switch

The ignition switch starts and stops the engine; it has three positions:

_OFF

Stops the engine and shuts off the electrical system.

_RUN

Allows the engine to run and powers the electrical system.

[_ START Cranks the engine for starting.

NOTE: Never leave the ignition switch in the RUN position with the engine stopped-this drains the battery.

Fuel Tank Cap

To remove the cap, turn counterclockwise.

Mower Cutting Height Adjustment Lever

The mower cutting height is adjustable from 1-1/2" to 4", in

1/2" increments. See CUTTING HEIGHT ADJUSTMENT for adjustment information.

Parking Brake

The parking brake is incorporated into the left motion control lever. Locking the lever into the neutral locked position engages the parking brake; moving the lever out from the neutral locked position disengages the brake.

Note: Both motion control levers must be locked into the neutral lock position together, or the un# will stall.

B Hour Meter

The hour meter measures the number of hours the key has been in the RUN position.

Note: The hour meter will register the passage of time when the engine is running.

The hour meter has a self contained power source so the total hours are always visible.

_PTO Switch

The PTO (Power Take-Off) switch engages and disengages the mower blade clutch. To engage the PTO, pull

UP on the switch. Push DOWN to disengage. Note that the operator must be seated firmly in the rider seat for the PTO to function.

I IMPORTANT

The figures and illustrations in this manual are provided for reference only and may differ from your specific model. Contact your dealer if you have questions.

Transmission Release Valves

The transmission release valves deactivate the transmis- sions so that the unit can be pushed by hand. See

PUSHING THE UNIT BY HAND for operational information.

Seat Adjustment Knobs

The seat can be adjusted forward and backward.

See

SEAT ADJUSTMENTS for adjustment information.

GENERAL OPERATING SAFETY

Before first time operation:

• Be sure to read all information in the Safety and

Operation sections before attempting to operate this rider and mower.

• Become familiar with all of the controls and how to stop the unit.

• Drive in an open area without mowing to become accustomed to driving the unit.

r , WARNING

Never operate on slopes greater than 27 percent

05°).

Select slow ground speed before driving onto a

slope. Use extra caution when operating on

slopes with a rear-mounted grass catcher.

Mow up and down slopes, not across the face, use caution when changing directions and DO

NOT START OR STOP ON SLOPE.

AWARNING

Never allow passengers to ride on the unit.

Before leaving the operator's position for any

reason, lock the motion control levers in the

neutral locked position, disengage the PTO, stop the engine and remove the key.

To reduce fire hazard, keep the engine, rider and

mower free of grass, leaves and excess grease.

Do not stop or park rider over dry leaves, grass or combustible materials.

Gasoline is highly flammable and must be handled with care. Never fill the tank when the

engine is still hot from recent operation. Do not

allow open flame, smoking or matches in the area.

Avoid over-filling and wipe up any spills.

WARNING

If you do not understand how a specific control functions, or have not yet thoroughly read the

FEATURES & CONTROLS section, do so now.

Do NOT attempt to operate the rider without first

becoming familiar with the location and function of ALL controls.

CHECKS BEFORE STARTING

Operation

ZERO TURN

DRIVING PRACTICE

The motion control levers of the zero turn rider are responsive, and learning to gain a smooth and efficient control of the rider's forward, reverse, and turning movements will take some practice.

Spending some time going through the maneuvers shown and becoming familiar with how the unit accelerates, travels, and steers -- before you begin mowing --is absolutely essential to getting the most out of the zero turn rider.

Locate a smooth, flat area of your lawn -- one with plenty of room to maneuver. (Clear the area of objects, people and animals before you begin.) Operate the unit at mid-engine speed during this practice session

(ALWAYS operate at full engine speed when mowing), and turn slowly to prevent tire slippage and damage to your lawn.

We suggest you begin with the Smooth Travel procedure to the right, and then advance through the forward, reverse, and turning maneuvers.

Smooth Travel

The motion control levers of the zero turn rider are responsive.

The BEST method of handling the ground speed levers is in three steps -as shown in Figure 3.

FIRST place your hands onto the levers as shown.

SECOND, to go forward gradually push the levers forward with your palms.

THIRD, to speed up move the levers farther forward.

To slow down smoothly, slowly move the levers toward neutral.

Figure 3.

Move Control

Levers Gradually

BA SIC DRIVING

Forward Travel Practice

Gradually move both motion control levers -- evenly

FORWARD from neutral. Slow down and repeat.

NOTE: Straight forward travel takes practice. If necessary, top speed can be balance-adjusted -- see the

Speed Balancing Adjustment in the Adjustments section near the back of this manual

Forward

Travel

Reverse Travel Practice

LOOK DOWN & BEHIND, then gradually move both motion control levers evenly BACK from neutral. Slow down and repeat.

NOTE: Practice backing up for several minutes before attempting to do so near objects. The rider turns as sharply in reverse as when going forward, and backing up straight takes practice.

Figure 5. Reverse Travel

Operation

Practice Turning Around a Corner

While traveling forward allow one lever to gradually return back toward neutral. Repeat several times.

NOTE: To prevent pivoting directly on the tire tread, it is best to keep both wheels going at least slightly forward.

Practice Turning In Place

To turn in place, "zero turn," gradually move one motion control lever forward from neutral and one lever back from neutral simultaneously.

Repeat several times.

NOTE: Changing the amount each lever is pulled--for-

ward or back, changes the "pivot point"you turn on.

Figure 6. Turning Around a Corner

ADVANCED DRIVING

Executing an End-Of-Row Zero

Turn

Your zero turn rider's unique ability to turn in place allows you to turn around at the end of a cutting row rather than having to stop and Yturn before starting a new row.

For example, to execute a right end-of row zero turn:

,

Slow down at the end of the row.

2.

Move the LEFT motion control lever forward slightly while moving the RIGHT motion control lever back to center and then slightly back from center.

3. Begin mowing forward again.

This technique turns the rider RIGHT and slightly overlaps the row just cut --eliminating the need to back up and re-cut missed grass.

As you become more familiar and experienced with operating the zero turn rider, you will learn more maneuvers that will make your mowing time easier and more enjoyable.

Remember, the more you practice, the better your control of the rider will be!

The maximum weight of a towed trailer should be less than 200 Ibs (91 kg). Secure the trailer with an appropriately sized clevis pin (A, Figure 9) and clip (B).

Excessive towed loads can cause loss of traction and loss of control on slopes.

Reduce towed weight when operating on slopes. The surface being driven on greatly impacts traction and stability. Wet or slippery surfaces can greatly reduce traction and the ability to stop or turn.

Carefully evaluate the surface conditions before operating the unit and trailer, and never operate on slopes greater than 10 °. See SLOPE OPERATION and TOWED

EQUIPMENT in the safety section of this manual for additional safety information.

SEAT ADJUSTMENTS

The seat and motion control levers should be adjusted so that operator's elbows are supported by the arm rests when his/her hands are on the controls, and the motion control levers can be moved through their full range of motion without contacting the operator's legs.

Seat Position Adjustment

See Figure 20. The seat can be adjusted forward and back. Remove the knobs (A), and loosen the support bolts (B). Slide the seat to the desired position, then reinstall the knobs and retighten the bolts.

MOTION CONTROL LEVER

ADJUSTMENT

The motion control levers can be adjusted in two ways.

The placement of the levers (how close the ends are to one another) and the height of the levers can be adjusted.

To Adjust the Lever Placement: Loosen the two bolts

(B, Figure 21) securing the control track, and adjust the control track in or out to properly adjust the lever end spacing.

Note: The bottom bolt may be accessed from beneath the fender.

To Adjust the Handle Height: Remove the motion control lever mounting hardware (A, Figure 21) and reposition the lever either up or down from its original position.

You may need to readjust the handle placement as described above.

SPEED BALANCING ADJUSTMENT

If the rider drifts to the right or left when the motion control levers are in the maximum forward position, the top speed of each of these levers can be balanced.

Only adjust the speed of the wheel that is traveling faster.

TO REDUCETHE SPEED OFTHE FASTER WHEEL

1. Loosen the two bolts securing the forward adjust plate (C, Figure 21).

2. Slide the plate up approximately 1/8".

3. Retighten the bolts and recheck speed balance.

4. Repeat steps 1-3 until adjustment is complete.

AWARNING

DO NOT adjust the rider for a faster overall speed forward or reverse than it was designed for.

23

MOTION CONTROL LEVER FRICTION

ADJUSTMENT

The motion control levers should be tight when moving in and out of their neutral locked positions.

If the levers are loose, the lever friction should be adjusted.

To adjust friction:

Loosen the outside nut (C, Figure 21a) securing the motion control lever (A) to the control bracket weldment

(B). Tighten the inner nut (D) against the bellville washer

(E) to 10 ft-lbs. Tighten the outside nut against the inside nut, without allowing the inside nut to turn.

NEUTRAL ADJUSTMENTS

If the machine creeps while the motion control levers are locked into their neutral locked positions, then it may be necessary to adjust the link rods.

Perform this adjustment on a hard level surface such as a concrete floor.

IMPORTANT NOTE: This adjustment should be performed with the engine OFF. Perform the adjustment, then start the engine to check the adjustment.

If further adjustment is required, stop the engine before performing the adjustment.

1. Determine which wheel is creeping. The left side transmission and link rod control the left wheel, the right link rod controls the right wheel.

2. Disengage the PTO, lock the motion control levers into their neutral locked positions, turn the engine off, remove the key, and wait for all moving parts to stop.

3. Remove the hardware (C, Figure 23) connecting the rod end (B) to the control bracket weldment (A).

Note: The rod end is located under the fender beside the operator seat.

4. Loosen the rod end jam nut (B).

If the transmission is creeping forward, turn the rod end in (clockwise) one or two turns to shorten the link rod (E).

If the transmission is creeping in reverse, turn the rod end out (counterclockwise) one to two turns to lengthen the link rod.

,

Retighten the jam nut, and reconnect the rod end to the control bracket weldment.

,

Start the unit and check for transmission creep.

Repeat steps 2-5 if necessary.

,

Once the correct neutral adjustment is achieved, check adjustment of the compression spring (F).

With the motion control levers in their neutral locked positions, the spring should have no compression, and should have approximately 1/16-1/8" of free play between the washers at either end. Turn the two adjustment nuts (G) in or out until the desired adjustment is achieved.

25

PARKING BRAKE ADJUSTMENT

Brake Adjustment

1. Disengage the PTO, stop the engine, block the front wheels, remove the ignition key, and lock the motion control levers into their neutral lock positions.

2. Elevate the rear end of the unit, making sure it is safely supported.

3. Before attempting brake adjustment, check the brake gear (A, Figure 23a), brake arm (B), park brake bracket (D), brake rod (E), and compression spring

(F) for dirt or debris that may affect brake operation.

4. Check to see that the brake arms (B) are engaged against the brake gears (A), with the teeth on the arms meshing with the teeth on the gears.

Note: The rear wheels may need to be moved slightly for the teeth to mesh properly.

5. With the parking brake disengaged (motion control levers moved from their neutral locked positions), measure the length of the compression spring (F).

The measurement should be between 2-1/2" and 2-

3/4". If not, tighten or loosen the brake rod adjustment nut (C) until the correct measurement is achieved.

FRONT SUSPENSION ADJUSTMENT

(SELECT MODELS)

The shock assembly can be adjusted to vary the amount of pre-load applied to the springs.

This allows the operator to customize the ride according to operator's weight and operating conditions.

LESS PRE-LOAD:

• Light operator weight

• Softer, more cushioned ride

• Best for relatively flat terrain

MORE PRE-LOAD:

• Heavy operator weight

• Stiffer, more rigid ride

• Better handling and greater stability on hilly terrain

TO ADJUST THE SPRING PRE-LOAD:

1. Park machine on a flat, level surface. Disengage the

PTO, stop the engine and engage the parking brake.

PTO CLUTCH ADJUSTMENT

Check the PTO clutch adjustment after the initial 25 hour break-in period and then after every 250 hours of operation. Also perform the following procedure if the clutch is slipping or will not engage, or if a new clutch has been installed.

1. Remove key from ignition switch and disconnect spark plug wires to prevent the possibility of accidental starting while the PTO is being adjusted.

2. See Figure 25. Note the position of the 3 adjustment windows (A) in the side of the brake plate and the nylock adjustment nuts (B).

3. Insert a .016"-.018" (0,40-0,45mm) feeler gauge (C) through each window, positioning the gauge between the rotor face and the armature face as shown in

Figure 26.

4. Alternately tighten the adjustment nuts (B, Figure 25) until the rotor face and armature face just contacts the gauge.

5. Check the windows for an equal amount of tension when the gauge is inserted and removed, and make any necessary adjustments by tightening or loosening the adjustment nuts.

NOTE: The actual air gap between the rotor and armature may vary even after performing the adjustment procedure.

This is due to dimensional variations on component parts, and is an acceptable condition.

6. Check the mower blade stopping time. The mower blades and mower drive belt should come to a complete stop within five seconds after the electric PTO switch is turned off.

WARNING

To avoid serious injury, perform adjustments only with engine stopped, key removed and rider on level ground.

BLADE BRAKE CHECK

Mower blades and mower drive belt should come to a complete stop within five seconds after electric PTO switch is turned off.

1. With parking brake engaged, PTO disengaged and an operator in the seat, start the engine engine.

2. Have an assistant observe the mower drive belt through the opening between the frame and top of mower deck. Engage the PTO and wait several seconds. Disengage the PTO and check the amount of time it takes for the mower drive belt to stop.

3. If the mower drive belt does not stop within five seconds, perform the PTO Clutch Adjustment.

If the belt still does not stop within 5 seconds, see your dealer.

MOWER DECK LEVELING

Perform these adjustments on a flat level surface. Be sure to check and adjust tire pressures before leveling the mower deck

SIDE-TO-SIDE LEVELING

1. With the mower installed, place the rider on a smooth, level surface such as a concrete floor. Turn the front wheels so they are straight.

2. Check for bent blades and replace if necessary.

3. Place the mower cutting height lever in the fourth adjustment notch from the bottom. Arrange the outside mower blades so that they are pointing from side-to-side (Figure 27).

4. Measure the distance between the outside tips of each blade and the ground (Figures 27 & 28). The measurement should be 3" (7,6 cm), +/-1/8" (3mm).

If there is more than 1/8" (3mm) difference between the measurements on each side, proceed to step 5. If the difference is 1/8" (3mm) or less, proceed to step 6.

5. Use the rear leveling nuts (A, Figure 29) to adjust the side-to-side leveling of the deck. Repeat step 4 if necessary.

FRONT-TO-BACK LEVELING

6. Arrange the blades so they face front-to-back (Figure

30).

7. Measure the distance from the ground to the front tip of the center blade and from the ground to the rear tip of the rear blades (Figures 28 & 30). The front tip of the front blade should be 1/4" (6mm) higher than the rear tips of the rear blades. If not, proceed with steps

8-9.

ROLLER BAR LEVELING

(If Equipped)

1. First level the mower deck using the procedure found in MOWER DECK LEVELING.

2. With the mower installed, place the rider on a smooth, level surface such as a concrete floor. Turn the front wheels so they are straight.

3. Place the cutting height adjustment lever in the top adjustment notch.

4. Measure the distance between the outside ends of the roller bar and the ground. If there is more than

1/8" (3mm) difference between the measurements on each side, proceed to step 5.

5. Locate the roller bar leveling hardware on the right side of the mower deck (A, Figure 32). Loosen the hardware and raise or lower the roller bar until the correct level is achieved, then tighten the hardware.

Repeat steps 4 & 5 if necessary.

TRANSMISSION DRIVE BELT

REPLACEMENT

1. Park the rider on a smooth, level surface such as a concrete floor. Disengage the PTO, lock the motion control levers into their neutral locked positions, turn off the engine, and remove the ignition key.

2. Remove the mower belt from the PTO pulley (see

MOWER BELT REPLACEMENT for instructions).

3. Relieve tension on the transmission belt (A, Figure

33a) by moving the idler arm (E) in the direction indicated by the curved arrow, and remove the old belt from the crankshaft and transmission pulleys.

4. Loosen (do not remove) the anti-rotation bracket hardware (C, Figure 33a), and slip the old belt out between the anti-rotation pin (B) and the PTO (A).

Note: The PTO wiring harness must be disconnected from the main wiring harness in order to remove and replace the transmission belt. Be sure to reconnect the harness after the belt is replaced.

5. Reversing steps 3-4, install the new belt, following the routing in Figure 33b. Make sure the V-side of the belt runs in the grooves of the crankshaft pulley and transmission pulleys (B & C). Also, make sure that the anti-rotation pin (B, Figure 33a) is inserted into the anti-rotation slot on the PTO before tightening hardware (C).

6. Reinstall the PTO drive belt.

BATTERY CHARGING

A dead battery or one too weak to start the engine may be the result of a defect in the charging system or other electrical component.

If there is any doubt about the cause of the problem, see your dealer. If you need to replace the battery, follow the steps under Cleaning the

Battery & Cables in the Regular Maintenance Section.

To charge the battery, follow the instructions provided by the battery charger manufacturer as well as all warnings included in the safety rules sections of this book.

Remove the battery from the rider and place on a level, non-concrete surface. Charge the battery at 6-10 amps for 1 hour. Do not charge at a rate higher than 10 amps.

WARNING

Keep open flames and sparks away from the

battery; the gasses coming from it are highly explosive. Ventilate the battery well during charging.

Engine Power Rating Information

The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive

Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Actual gross engine power may be lower and is affected by, but not limited to, ambient operating conditions and engine to engine variability. Given both the wide array of products on which engines are placed, and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual

"on-site" or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions

(temperature, humidity, altitude), and engine to engine variability.
