UNIT DESCRIPTIONS

Implement Hitch

The implement hitch is required to mount each of the implements to the tractor. It clips on the tractor in place of the mower deck in less than a minute.

Each implement slides on the male hitch and easily locks in place. The mount assembly also includes operator footrests and an electric power lift. The lift control switch is mounted on the FSC lever for convenient operator use, and is powered by the linear actuator on the implement hitch.

Dozer Blade

The 46-inch (117 cm) dozer blade has a five-position RH/LH angle adjustment. It is used for removal of snow, loose dirt, and gravel, and is raised and lowered automatically with the lift control switch.

The dozer blade is designed to “trip” forward when striking a large object, eliminating shock to the tractor and operator. Tire chains and a soft cab are available as optional equipment.

Rotary Broom

The rotary broom has a 47-inch (119 cm) sweeping path and five-position RH/LH angle head. It is suitable for light snow removal, lawn dethatching/raking and general hard surface sweeping. It is raised and lowered automatically with the lift control switch. The rotary broom is powered by the tractor

PTO through the PTO shaft, gearbox and chain final drive to brush drive shaft. Tire chains and a soft cab are available as optional equipment.


The 42-inch (107 cm) two-stage snowblower throws snow up to 40 ft (12 m). It is raised and lowered automatically with the lift control switch. The blower spout is controlled with a simple position control handle. The snowblower is powered by the tractor PTO through the PTO shaft, snowblower drive shaft, and gearbox. Tire chains and a soft cab are available as optional equipment.

Debris Blower

The debris blower is used for parking lot cleaning and leaf control. It is raised and lowered automatically with the lift control switch. The directional spout adjusts manually. The debris blower is powered by the tractor PTO through the PTO shaft.

Tire chains and a soft cab are available as optional equipment.

IMPORTANT: These implements are not intended for use with Model MS tractors.

BEFORE OPERATING

1.

Read and understand the contents of this

OWNER'S MANUAL before operating the

machine. Become thoroughly familiar with all controls and how to stop the machine and disengage the controls quickly. Replacement Owner's

Manuals are available by sending the Model and

Serial Number to:

Walker Manufacturing Company

5925 E. Harmony Road

Fort Collins, CO 80528

2.

Never allow children to operate or give rides

on the machine. Do not allow adults to operate without proper instruction.

3.

Do not allow anyone other than the operator on the machine.

4. Keep everyone, especially children and pets, a safe distance away from the area being cleaned.

Do not operate with bystanders in the area.

5. Do not operate the machine wearing sneakers, tennis shoes, or similar lightweight footwear.

Wear substantial protective footwear that will improve footing on slippery surfaces.

6. The snow or leaves can sometimes hide objects that might clog the snowblower or debris blower chute, or otherwise cause damage. Clear the area of doormats, sleds, boards, wires and other debris.


7. Do not wear loose fitting clothing that could get caught in moving parts. Always wear ade-

quate protective clothing including long pants.

Wearing safety glasses, safety shoes, and a helmet is advisable and required by some local ordinances and insurance regulations.

8. Prolonged exposure to loud noise can cause impairment or loss of hearing. Operator hear-

ing protection is recommended. Wear a suitable hearing protective device, such as earmuffs or earplugs.

9. Keep all protective shields and safety devic-

es in place. If a protective shield, safety device, or decal is damaged, unusable, or missing, repair or replace it before operating the machine.

10. Be sure any interlock switches are function-

ing correctly so the engine cannot be started unless the Forward Speed Control lever is in the NEUTRAL position and the PTO clutch is in the DISENGAGED position. Also, the engine should stop if the operator lifts off the seat with the PTO clutch in the ENGAGED position.

11. Never attempt to make any adjustments

while the engine is running, except where specifically instructed to do so.

12. Handle gasoline or diesel fuel with care.

Gasoline is highly flammable and its vapors are explosive: a.

Use an approved fuel container.

b.

Never add fuel to a running engine or hot engine (allow hot engine to cool several minutes).

c.

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

d.

Always fill the fuel tank outdoors using care. Fill to about one inch from the top of the tank. Use a funnel or spout to prevent spilling.

e. Replace the machine fuel cap and container cap securely and clean up any spilled fuel before starting the engine.

OPERATING

NOTE: Refer to the Walker Rider Lawnmowers

OWNER’S MANUAL for safety instructions for operating the tractor.

1. Operate the machine only in daylight or in good artificial light with good visibility of areas being cleaned.

2. Sit on the seat when starting the engine and operating the machine. Keep feet on footrests at all times when the tractor is moving and/or the implement is operating.

3.

An inexperienced operator should learn to steer

(maneuver) the tractor with a slow engine

speed before attempting any operating. Be aware that, with the front mounted implement configuration, the back of the machine swings to the outside during turns.

4. Remember, for an emergency stop, the forward motion of the tractor can always be stopped by pulling the Forward Speed Control (FSC) into the NEUTRAL-PARK position.

5. Disengage the PTO clutch and put the FSC in the NEUTRAL-PARK position before starting the engine (an ignition interlock switch normally prevents starting of the tractor if these controls are in the OPERATING position).

6. Do not run the engine in a confined area with-

out adequate ventilation. Exhaust fumes are hazardous and can be deadly.

7. Do not carry passengers - maximum seating capacity is one (1) person.

8.

Make sure the auger, brush, or debris blower is clear of snow, ice, or debris before engaging the

PTO clutch.

9.

Be careful never to throw snow or blow debris towards people or cars, and never allow anyone in front of the implement.

10. Watch out for hazards hidden under snow or leaves that could enter the chute or blower while operating.

11. Avoid sudden starts or stops. Before backing the machine up, look to the rear to be sure no one is behind the machine. Watch carefully for traffic when crossing or working near roadways.

15

16


12. Disengage the PTO clutch when transporting the machine.

13. Do not operate across the face of slopes. Use extreme caution when changing direction on slopes. Do not attempt to clear steep slopes.

14. Never adjust gauge wheels or skid shoes

with the engine running. Before adjusting height or servicing, disengage the PTO clutch, stop the engine, and remove the ignition key.

Wait for all movement to stop before getting off the seat.

NOTE: The PTO brake should normally stop drive line rotation within 5 seconds of disengaging the PTO clutch.

15. Do not operate the snowblower with the blower spout assembly removed.

16. If snowblower clogs: a. Disengage the PTO clutch, stop the engine, and remove the ignition key before leaving the seat.

b. LOOK to make sure PTO shaft and auger movement has stopped before trying to unclog the snowblower.

c. Disconnect the fuel solenoid wire [diesel engines] or spark plug wire(s) [gasoline engines].

d.

Do not use hands or feet to unclog the snowblower - use a stick or similar tool.

17. If the implement strikes a solid object or the machine begins to vibrate abnormally, immediately disengage the PTO clutch, stop the engine,

and wait for all moving parts to stop. Disconnect the fuel solenoid wire [diesel engines] or the spark plug wire(s) [gasoline engines] to prevent accidental starting. Thoroughly inspect the implement and repair any damage before restarting the engine and operating the machine.

Make sure implement components are in good condition and all bolts are tight.

18. Do not touch the engine or muffler while the

engine is running or immediately after stopping the engine. These areas may be hot enough to cause serious burns.

19. When leaving the machine unattended, disengage the PTO clutch, stop the engine, and remove the ignition key.

MAINTENANCE

NOTE: Refer to the Walker Rider Lawnmowers

OWNER’S MANUAL for proper tractor maintenance procedures.

1. To prevent accidental starting of the engine when servicing or adjusting the machine, remove the key from the ignition switch and disconnect the fuel solenoid wire [diesel engines] or the spark plug wire(s) [gasoline engines].

2. To reduce fire hazards, keep the engine free of grass, leaves, excessive grease, and dirt.

3. Keep all nuts, bolts, and screws tight to ensure the machine is in a safe, working condition.

4. Perform only maintenance instructions de-

scribed in this manual. Unauthorized maintenance operations or machine modifications may result in unsafe operating conditions.

5. If the engine must be running to perform a maintenance adjustment, keep hands, feet, and clothing away from moving parts. Do not wear jewelry or loose clothing.

6. Always use proper engine service manuals

when working on the engine. Unauthorized maintenance operations or modifications to the engine may result in unsafe operating conditions.

7. Altering the machine in any manner which adversely affects its operation, performance, durability, or use will VOID the warranty and may cause hazardous conditions.

8. Never attempt to disconnect any safety devices or defeat the purpose of these safety devices.

9. Do not change the engine governor settings or overspeed the engine. The governor has been factory-set for maximum-safe engine operating speed.

10. Use genuine factory replacement parts. Substitute parts may result in product malfunction and possible injury to the operator and/or others.

IMPORTANT: Keep all applicable manuals immediately accessible to anyone who may operate or service this machine.


SAFETY, CONTROL, AND INSTRUCTION DECALS

TRACTOR CONTROLS

Refer to the appropriate Tractor Owner’s Manual for complete information about tractor operating controls.

WARNING

Before operating the implements, become familiar with the location and function of all operator controls. Knowing the location, function, and operation of these controls is important for safe and efficient operation of the implements.

STARTING THE MACHINE

CAUTION

ALWAYS disengage the PTO clutch and put the FSC in the NEUTRAL-PARK position before starting the engine.

Refer to the appropriate Tractor Owner’s Manual for tractor starting and operating procedures.

NOTE: For cold weather operation, follow the proper operating procedures in the appropriate Tractor

Owner’s Manual. Allow sufficient time for the tractor engine to warm up before engaging the machine.

IMPLEMENT HITCH CONTROLS

Implement Lift Switch

All of the implements may be raised or lowered by operating a toggle switch located on the FSC lever.

Move the switch forward to lower the implement.

Move the switch backward to raise the implement.

NOTE: The same procedure is used to raise or lower the implement regardless of which implement is mounted on the tractor.

Trip Spring

The dozer blade was designed to “trip” forward when striking large rocks, tree stumps, etc. Once the blade clears the obstacle, the blade will spring back to the normal operating position, eliminating the shock to the operator and tractor. Adjust the trip spring tension by raising and lowering the eyebolt and retightening the nut to the amount of tension required for safe operation. [Normally about 1/2 in.

(13 mm) of thread should protrude beyond the nut.]

CAUTION

DO NOT strike large objects with the dozer blade during rigid blade operation.

Speed Recommendations

For maximum power, set the engine speed control in

FAST (full power) position. Use the forward speed control arm to control the ground speed best suited for the job being done. Use faster speeds for lighter snow removal, and slower speeds for heavier snow removal.

ROTARY BROOM CONTROLS

Ground Contact Knob

Turning the ground contact knob clockwise de-

creases brush ground contact pressure. Turning the knob counterclockwise increases brush ground contact pressure. Once the knob is adjusted, it should only be used to compensate for brush wear.

IMPORTANT: Adjust the brush to ground contact pressure so that the broom head, when lifted by the front, weighs approximately 30 to 50 lb (14 to 23 kg).

More weight than this may cause premature brush wear and overheating of the gearbox.

Raising and Lowering the Broom


Engaging the Rotary Broom

1.

Set the engine throttle at about 1/3 speed. DO

NOT attempt to engage the PTO clutch at

high engine speeds. This will drastically shorten drive belt life. Use only moderate engine

speed when engaging the PTO clutch.

2.

Pull the PTO clutch lever SLOWLY to engage the rotary broom.

NOTE: For cold weather operation, allow sufficient time for the rotary broom components (i.e., gearbox oil) to warm up before beginning to operate.

CAUTION

A safety interlock switch (seat switch) will cause the engine to stop if the PTO clutch is engaged and the operator is not in the seat. The function of this switch should be checked by the operator raising off the seat and engaging the PTO clutch; the engine should stop. If the switch is not working, it should be repaired or replaced before operating the rotary broom. DO

NOT disconnect the safety switches; they are for the operator’s protection.

IMPORTANT: DO NOT engage the PTO clutch when transporting the machine. DO NOT en- gage the PTO clutch with the PTO shaft dis-

connected (the rotary broom removed from the tractor).

Minimize dust by reducing brush speed and by sweeping on days with high moisture.

2.

For light material, angle the broom 12.5 de-

grees right or left, rather than the fully angled

25 degrees, to obtain a wider sweeping path.

3.

Prevent damage to the broom by removing large foreign objects from the sweeping area prior to operation.

IMPORTANT: For efficient operation, sweep with the tips of the bristles like a broom; not with the sides of the bristles like a mop.

37

38


Snow Removal

WARNING

Foreign objects in snow may be thrown farther than the snow. Use the slowest brush speed that will perform the job.

Stay aware of the broom discharge direction at all times.

1.

The rotary broom works best on snow depths of

4 in. (10 cm) or less. Larger amounts of snow can be moved if the ground speed is reduced.

2.

To avoid snow being blown back onto the tractor and operator, sweep with the wind blowing in the direction of broom discharge.

Lawn Thatching and Leaf Raking

CAUTION

Optional gauge wheels must be installed to perform these types of operation in order to avoid excessive brush ground contact.

1.

Bristles should barely touch the ground for lawn thatching, and barely touch the grass in leaf raking operations.

2.

Slower brush speed and ground speed are more adequate for lawn thatching. This will prevent “bouncing” which could damage the lawn due to excessive ground contact.

3.

Minimize dust by sweeping when moisture is high (but not wet) whenever possible.

TWO-STAGE SNOWBLOWER CONTROLS

Chute Rotation Handle

The chute rotation handle is located on the rear of the snowblower head, on the lower RH side of the discharge chute. The chute rotates in a 228 degree arc, by cranking the rotation handle. Turning the handle clockwise rotates the chute clockwise.

Turning the handle counterclockwise rotates the chute counterclockwise.

TWO-STAGE SNOWBLOWER OPERATION

CAUTION

Before operating the snowblower, read and understand all Safety Instructions and


Raising and Lowering the Snowblower



Engaging the Snowblower

1.

Make sure that the snowblower is clear of snow and/or ice before engaging the snowblower.

2.

Make sure that the auger and fan operate freely.

3.

Check the oil level in the worm gearbox and if necessary, add SAE 90 E.P. (Extreme Pressure) oil. Make sure the oil level is up to the side plug. (Refer to LUBRICATION of Two-Stage

Snowblower Gearbox in Maintenance Instructions.

)

4.

Check the three (3) shear bolts, one on each auger section, and one between the fan and gearbox for proper tightness, approximately 8 ft-lb

(11 N·m).

5.

Adjust the snowblower so that it runs level.

6.





7.

Pull the PTO clutch lever SLOWLY to engage the snowblower.

NOTE: For cold weather operation, allow sufficient time for the snowblower components (i.e., gearbox oil) to warm up before beginning to blow snow.

DANGER

A safety interlock switch (seat switch) will cause the engine to stop if the PTO clutch is engaged and the operator is not in the seat. The function of this switch should be checked by the operator raising off the seat and engaging the PTO clutch; the engine should stop. If the switch is not working, it should be repaired or replaced before operating the snowblower. DO


IMPORTANT: DO NOT engage the PTO clutch when transporting the machine. DO NOT engage the PTO clutch with the PTO shaft disconnected

(the snowblower removed from the tractor).

DANGER

If the auger strikes a solid object or the machine begins to vibrate abnormally, immediately disengage the PTO clutch, stop the engine, and wait for all moving parts to stop. Disconnect the fuel solenoid wire

[diesel engines] or the spark plug wire(s)

[gasoline engines] to prevent accidental starting. Thoroughly inspect the snowblower and repair any damage before restarting the engine and operating the machine. Make sure auger blades are in good condition and all bolts are tight.

•

When operating on a slope, reduce speed and

use caution to start, stop, and maneuver. Avoid sharp turns or sudden changes in direction.

•

When blowing through deep snow drifts, let the snowblower work its way through the drifts. For best results, raise the snowblower and remove a top layer of snow, then pass through the area a second time to remove the remaining snow.

•

When snowblowing, operate the engine at or near

full throttle for the best snowblowing action. The engine is designed to be operated at full speed.

•

Use optional tire chains or optional all-terrain tires to improve traction.

•

Disengage the PTO clutch to stop the snowblower when driving the machine but not blowing snow.

•

Avoid damage to property and extra snowblowing work by carefully choosing the direction to move the snow. Orient the blower away from people and property due to the possibility of thrown objects.

•

To momentarily increase traction in case the drive wheels are slipping, use the lift switch to raise the snowblower slightly and transfer extra weight on the drive wheels.

Removing Snow

DANGER

DO NOT blow snow with bystanders in the area (especially children or pets).

A definite operating pattern is required to thoroughly clean snow from an area. Each pattern described below clears all the snow in one pass (of the pattern) and prevents throwing snow in unwanted places.

IMPORTANT: DO NOT use the snowblower as a dozer blade to push snow. Let the snowblower work its way through deep snow. If the tractor is driven forward into snow too fast, the snowblower may become overloaded and clog.

Use the following pattern where snow can be thrown only to one side. Start on the side farthest from

where the snow will be thrown. At the end of the first pass, rotate the blower spout 180 degrees for

the return pass. At the end of each following pass, rotate the spout 180 degrees to keep throwing snow in the same direction.

Throw Snow to One Side

Use the following pattern where snow can be thrown to both sides. Start in the middle with the blower

spout directed to either the right or left. Drive from one end to the other in an outward spiral,

without changing the position of the blower

spout to throw snow to both sides.

Throw Snow to Both Sides

Clogging Checklist

In case of clogging, the snow throwing action will decrease and finally stop. When this occurs, disengage the PTO clutch, stop the engine, disconnect the fuel solenoid wire [diesel engines] or spark plug wire(s) [gasoline engines], and remove the ignition key. Make sure all movement has stopped before attempting to unclog.


DANGER

DO NOT attempt to unclog the snowblower or make any adjustments with the tractor engine running. Disengage the PTO clutch, stop the engine, and remove the ignition key.

Chute Rotation

Handle

DANGER

NEVER place hands in the blower spout.

DO NOT use hands or feet to unclog the snowblower. Use a short stick or similar tool to remove any clogged material.

The following list of items should be checked if a pattern of clogging begins to develop. All of these items are capable of causing clogging.

•

Check that the inside of the snowblower housing is clean and free of snow and/or ice buildup.

•

Check that the auger is in good condition and not bent, both the auger flighting and the center paddles.

•

Check the inside of the blower spout for smooth- ness and freedom of obstruction.

Remember, anything that restricts airflow or material flow along the entire path from the auger to the blower spout can cause clogging.

DEBRIS BLOWER CONTROLS


The chute rotation handle is located on the rear of the debris blower, on the upper RH side of the impeller housing. The chute rotates in a 230 degree arc, by cranking the rotation handle. Turning the handle clockwise rotates the chute clockwise.

Turning the handle counterclockwise rotates the chute counterclockwise.


Deflector Position Control Knob

Set the angle of the deflector according to the distance the debris must be thrown. To adjust the deflector angle, loosen the knob on the RH side of the deflector, slide the deflector to the required angle, and securely retighten the knob.

Recommendations For Operating the Debris

Blower

IMPORTANT: Operate the engine at full speed when operating the debris blower, to allow the engine to produce full horsepower and to increase efficiency of the engine cooling system.

•

When operating on a slope, reduce speed and

use caution to start, stop, and maneuver. Avoid sharp turns or sudden changes in direction.

•

Use optional tire chains or optional all-terrain tires to improve traction.

•

Disengage the PTO clutch to stop the debris blower when driving the machine but not operating the debris blower.

•

Avoid damage to property and extra cleaning work by carefully choosing the direction to move the debris. Orient the blower away from people and property due to the possibility of thrown objects.

•

To momentarily increase traction in case the drive wheels are slipping, use the lift switch to raise the debris blower slightly and transfer extra weight on the drive wheels.

STOPPING THE MACHINE

1.

Slow the engine to idle; put the throttle in the

IDLE position.

2.

Pull the steering levers to the NEUTRAL position and then move the FSC lever backward to the NEUTRAL-PARK position.

3.

Disengage the PTO clutch.

IMPORTANT: DO NOT disengage the PTO clutch with high engine speed (above 1/2 throttle) since the brake action on the PTO drive will cause premature wear of the brake band.

WARNING

A brake stops the machine from freewheeling within five (5) seconds after disengaging the PTO clutch. If the brake system malfunctions and the machine does not stop within five (5) seconds, the brake should be adjusted or repaired before operating the machine. Refer to the appropriate Tractor Owner’s Manual for adjustment procedures.

4.

Turn the ignition switch OFF.

WARNING

Remove the key from the ignition switch when leaving the machine unattended.

This will prevent children and inexperienced operators from starting the engine.

5.

Engage the parking brake.

IMPORTANT: The hydrostatic transmissions lock to prevent the machine from rolling freely with the engine stopped. However, if the machine is parked on a slope, it is necessary to

ENGAGE the parking BRAKE to prevent the machine from creeping. This is due to a small amount of slippage in the hydrostatic transmissions, especially when transmission fluid is warm.


CAUTION

Maintenance procedures requiring special training or tools should be performed by a trained technician.
