Never aiiow adults to operate the equipment without proper instruction. Keep the area of operation clear of all persons,
especially small children, and pets. Thoroughly inspect the area where the equipment is to be used and remove all door mats, sleds, boards, wires and other foreign objects. Disengage all clutches and shift into neutral before starting engine. Do not operate equipment without wearing adequate winter outer garments. Wear substantial footwear which will protect feet and improve footing on slippery surfaces. Check fuel before starting the engine. Do not remove the fuel cap or fill the fuel tank while the engine is running or hot. Do not fill the fuel tank indoors. Gasoline is an extremely flammable fuel. Make sure the snow thrower height is adjusted to clear the type surface it will be used on. Do not use the snow thrower without wheel weights attached to the tractor. Never make any adjustments while the engine is running. Always wear safety glasses or eye shield during operation or while performing adjustment or repair. Do not place hands or feet near rotating parts. Keep clear of the discharge opening at all times. Use extreme caution when operating on or crossing gravel surfaces. Do not carry passengers. After striking a foreign object, stop the engine, remove the wire from the spark plug and then thoroughly inspect the snow thrower for damage. Repair any damage before restarting and operating the snow thrower.
If the snow thrower starts to vibrate abnormally, stop the engine immediately and check for the cause. Vibration is generally a warning of trouble.
Stop the engine whenever you leave the operating position, before unclogging the snow thrower or making any adjustments or inspections. Take all possible precautions when leaving the unit unattended. Disengage the attachment clutch lever or switch, lower the snow thrower, shift into neutral, set the parking brake, stop the engine and remove the key. When cleaning, repairing or inspecting, make certain all moving parts have stopped. Disconnect the spark plug wire and keep it away from the plug to prevent accidental starting. Do not run engine indoors except when transporting the snow thrower in or out of the building. Open the outside doors. Exhaust fumes are dangerous. Do not clear snow across the face of slopes. Exercise extreme caution when changing direction on slopes. Do not attempt to clear steep slopes. Refer to the slope guide on page 35 of this manual. Never operate the snow thrower without guards, plates or other safety protection devices in place. Never operate the snow thrower near glass enclosures, automobiles, window wells, drop offs etc. without proper adjustment of the snow thrower discharge angle. Never direct discharge at bystanders or allow anyone in front of the snow thrower. Never run the snow thrower into material at high speeds. Do not overload the machine capacity by attempting to clear snow at too fast a rate. Never operate the machine at high transport speed on slippery surfaces. Look behind and use care when backing up. Watch for traffic and stay alert when crossing or operating near roadways. Disengage power to the snow thrower when transporting or when not in use. Use only attachments and accessories approved by the manufacturer of the snow thrower (such as wheel weights, counter weights, cabs etc.) Never operate the snow thrower without good visibility or light.

REMOVING SNOW

Snow removal conditions vary greatly from light fluffy snowfall to wet heavy snow. Operating instructions must be flexible to fit the conditions encountered. The operator must adapt the lawn tractor and snow thrower to depth of snow, wind direction, temperature and surface conditions.
• Before beginning operation, thoroughly inspect the area of operation and remove all door mats, sleds, boards, wires and other foreign objects.
• The spiral auger speed is directly related to engine speed. For maximum snow removal and discharge, maintain high engine r.p.m. (full throttle). It is advisable to operate the lawn tractor at a slow ground speed (1st gear) for safe and efficient snow removal.
In deep, drifted or banked snow it will be necessary to use full throttle and a slow ground speed (1 st gear). Drive forward into the snow, depress the tractor's clutch-brake pedal and allow the spiral auger to clear the snow. Repeat this method until a path is cleared. On the second pass, overlap the first enough to allow the snow thrower to handle the snow without repeated stopping and starting of forward motion.
traction and stability.
In extremely deep snow, raise the snow thrower from the ground to remove the top layer and drive forward only until the tractors front tires reach the uncleared bottom layer of snow. Depress the tractor's clutch­brake pedal and allow the spiral auger to clear the snow. Reverse the tractor and lower the snow thrower to the ground. Drive the tractor forward until the snow again becomes too deep. Repeating this process into and out of drifts will eventually clear even the deepest of snow piles.
If the snow thrower becomes clogged with snow or jammed with a foreign object, disengage the snow thrower immediately and shut off the tractor engine. Unclog the snow thrower before resuming operation.
DANGER: Shut off engine and
disengage snow thrower before unclogging discharge chute. Unclog using
A
a wooden stick, not your hands.

OPERATING TIPS

• Discharge snow down wind whenever possible.
• To help prevent snow from sticking to the snow thrower, allow the snow thrower to reach outdoor temperature before using it. A light coat of wax may also be applied to the inside surface of the snow thrower housing and discharge chute.
• Use tire chains to improve traction.
• Use rear wheel weights to improve traction.
Before the first snowfall, remove all stones, sticks and other objects which could become hidden by the snow.
Permanent obstacles should be marked for visibility.
• Overlap each pass slightly to assure complete snow removal.

• Assemble the belt onto the clutch/idler assembly.

SKID SHOE ADJUSTMENT

• The skid shoes are mounted on each side of the spiral auger housing. They regulate the distance the scraper plate is raised above the plowing surface. When removing snow from a gravel driveway or and uneven surface, it is advisable to keep the scraper plate as high above the surface as possible to prevent possible damage to the spiral auger. On blacktop or concrete surface, keep the scraper plate as close to the surface as possible.
Raise the snow thrower off the ground and place a block under each end of the scraper plate. Loosen the six hex nuts securing the skid shoes to the housing. Adjust the skid shoes up or down and retighten the nuts securely. Adjust both skid shoes to the same height to keep the housing and the scraper plate level. See figure 59.

LIFT RELEASE CABLE ADJUSTMENT

If the lift rod does not lock the snow thrower securely in the transport position, loosen the upper hex nut on the lift bracket a few turns and tighten the lower hex nut. Refer to figure 48 on page 22.
If the lift rod fails to unlock completely to lower the snow thrower, loosen the lower hex nut on the lift bracket a few turns and tighten the upper hex nut.
Refer to figure 48 on page 22.

CLUTCH DISENGAGEMENT ADJUSTMENT

(For tractors with engagement rod clutches only. Not for electric clutches or cable clutches)
If the spiral auger on the snow thrower does not stop when the attachment clutch lever on the tractor is disengaged, then adjustment is necessary. Proceed as follows. Refer back to figure 33 on page 17.
Place the attachment clutch lever in the disengaged position.
Remove the hairpin cotter from the engagement rod trunnion and lift the trunnion out of the hole in the idler arm.
• Screw the trunnion a few turns towards the front end of the rod.
Replace the trunnion into the hole in the idler arm and secure it with the hairpin cotter. Check the operation of the snow thrower. If the spiral augers still do not stop, repeat the above steps until the augers stop when the attachment clutch lever is placed in the disengaged position.

SPIRAL AUGERS

• The spiral augers are secured to the auger shaft with two shear bolts and nylock nuts. If you hit a foreign object or if ice jams the augers, the snow thrower is designed so that the bolts will shear.
If the augers will not turn, check to see if the shear bolts have sheared. See figure 60. Two replacement shear bolts and nylock nuts have been provided with the snow thrower. For future use order part number 710-0890A shear bolt and number 47810 nylock nut.
