SaFeTY

Any power equipment can cause injury if operated improperly or if the user does not understand how to operate the equipment.

Exercise caution at all times, when using power equipment.

• Read this owner's manual carefully and know how to operate your snow thrower and how to stop the unit and disengage the controls quickly.

• Never allow children to operate the equipment.

• Never allow 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 the rear weight 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.

Look for this symbol to point out important safety precautions. It means —

attention!! Become alert!! Your safety is involved.

1. All assembly instructions have been completed with all bolts and nuts properly tightened.

2. Check the engine belt and the auger belt. Make sure they are routed properly around pulleys and inside all belt keepers.

3. Check discharge chute for proper rotation.

4. Check operation of tilt control for upper chute.

5. Verify that the lift handle will lock into and release from the raised transport position. (Refer to the Service and

Adjustments section.)

6. Check skid shoe adjustment. (Refer to the Service and

BeFore STarTING

• Use the end of assembly checklist to verify that all instructions have been properly completed.

• Make sure the skid shoes are adjusted to maintain adequate ground clearance between the snow thrower and the type of surface to be cleared. (Refer to the Service and Adjustments section.)

• Make sure the tractor engine has the correct oil for winter operation (SAE 5W-30). Refer to tractor owner's manual.

How To STarT Your SNow THrower

• The tractor should be sitting with the engine running at full throttle. Move the attachment clutch to the engaged position, starting the snow thrower before the tractor clutch is engaged.

How To SToP Your SNow THrower

• To stop the snow thrower, disengage the tractor's attachment clutch lever for manual clutches or the clutch switch for electric clutches. Refer to your tractor owner's manual.

How To uSe Your SNow THrower

CauTIoN

: Never direct discharge towards bystanders or windows. Do not allow anyone in front of unit.

25

CoNTroLLING SNow DISCHarGe

• To control the direction snow is thrown, the discharge chute has 180 degrees of rotation. Turn the crank rod clockwise to rotate the chute to the right. Turn the crank rod counterclockwise to rotate the chute to the left.

• To control the distance snow is thrown, the upper section of the discharge chute pivots up and down.

Push forward on the chute tilt handle to pivot the chute down, decreasing the distance snow is thrown.

Pull back on the handle to pivot the chute up, increasing the distance snow is thrown.

raISING aND LowerING

• To raise, push down on the lift handle until the snow thrower locks in the raised transport position.

• To lower, push down slightly on the lift handle and pull the trigger. With the trigger pulled, slowly lower the snow thrower until it reaches the ground.

CauTIoN

: Do not operate the snow thrower without the rear weight attached to the tractor to provide extra 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.

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 (1st 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.

DaNGer

: Shut off engine and disengage snow thrower before unclogging discharge chute. Unclog using 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.

Service Dates

CHeCK SCraPer aND SHoeS For wear

(Refer to figures 59 and 60 on page 27)

• The scraper plate and skid shoes on the bottom of the snow thrower are subject to wear. To prevent damage to the spiral auger housing, replace plate and shoes before wear is excessive.

CauTIoN

: Before servicing or adjusting the snow thrower, shut off the engine, remove the spark plug wire(s), set the parking brake and remove the key from the tractor ignition.

rePLaCING auGer BeLT

• Disengage the tractor's attachment clutch.

• Lower the snow thrower to the ground.

• Remove the attachment pin.

• Lock the snow thrower's lift handle in the down position to decrease belt tension.

• Release the spring tension from the auger belt idler arm on the bottom of the clutch/idler assembly.

• Remove the auger drive belt from the clutch/idler assembly and from the spiral auger housing.

• Install new belt over top of large auger drive pulley and under the two side idler pulleys. Twist the belt 1/4 turn to seat the "V" of the belt in the groove of each idler pulley. Refer to figure 55 on page 23.

• 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.

SerVICe aND aDJuSTMeNTS

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 21.

• 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 21.

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 16.

• 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.
