Assembly Instructions 14. For GHS (Grass Handling System) equipped Walker tractors, install a blower intake cover in the blower intake tube. The cover “unloads” the blower and seals the intake to effectively eliminate power loss and noise when the blower is not being used. Refer to GHS Blower Intake Cover illustration for ROTARY BROOM in this section. 5. Reinstall the belt guard by reversing the removal procedure. 6.
Assembly Instructions 9. For stability of the tractor when transporting with the debris blower in raised position, approximately 80 lb (36 kg) of counterweight should be installed on the tail of the tractor. Optional tail weights for the various tractor models are available from your Walker dealer or a sandbag or similar weight may be used.
Assembly Instructions CHECK BROOM ANGLE ADJUSTMENT Refer to Angle Adjustment Lever in Operating Instructions. CHECK DRIVE CHAIN CHECK CHUTE AND DEFLECTOR • Make sure the chute and deflector are not clogged with snow and/or ice. • Turn the chute rotation handle and rotate the chute. The chute should rotate freely. Refer to LUBRICATION for Rotary Broom Drive Chain in Maintenance Instructions. Refer to ADJUSTMENTS of Rotary Broom Drive Chain Tension in Maintenance Instructions.
Operating Instructions 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. 2. 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. To avoid snow being blown back onto the tractor and operator, sweep with the wind blowing in the direction of broom discharge.
Operating Instructions 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.
Operating Instructions • 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.
Operating Instructions 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.
Operating Instructions Engaging the Debris Blower 1. 2. 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. Pull the PTO clutch lever SLOWLY to engage the debris blower. NOTE: For cold weather operation, allow sufficient time for the debris blower components to warm up before beginning to blow debris. WARNING the debris.
Maintenance Instructions CAUTION Maintenance procedures requiring special training or tools should be performed by a trained technician.
Maintenance Instructions LUBRICATION LUBRICATION 4. If the lubricant is flowing out of the plug hole, the gearbox is full. Reinsert the plug. If no lubricant flows out, add SAE E.P. (Extreme Pressure) 90W oil into the gearbox through the plug hole until it starts to flow out. 5. Wipe the threads of the gearbox plug before reinstalling. 6. Torque screws to 24 in-lb (2.7 N·m). WARNING DO NOT attempt to lubricate the machine with the tractor engine running.
Maintenance Instructions LUBRICATION Two-Stage Snowblower Gearbox Two-Stage Snowblower Reduction Chain The gearbox is permanently lubricated (oil filled) and sealed requiring no scheduled lubrication. However, the gearbox oil seal(s) should be checked every 25 hours for indication of an oil leak. If an oil leak is noted, replace the oil seal(s) and relubricate the gear-box as follows: Lubricate the reduction chain every 25 hours. A light penetrating oil or special purpose chain oil is recommended.
