Any power equipment can cause injury if operated improperiy 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 ail 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 ad equate 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 and adjustment or repair. Do not place hand 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 transport ing 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 23 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 enclo sures, 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 attempt ing 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. Watch for traffic and stay alert when crossing or operating near roadways. Disengage power to the snow thrower when trans porting 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.

CHUTE TILT HANDLE Pivots the Upper Chute up or
down to control the angle and distance of discharge.
CRANK ROD Rotates the Lower and Upper Chutes to
control the direction of discharge. LEVELING SHOE Helps maintain the snow thrower in a level position. LIFT HANDLE Used to lift or lower the snow thrower
to transport or operating position. LIFT RELEASE TRIGGER Releases the lock which
holds the snow thrower in the up, transport position.
0gPORE STARTING
• Use the end of assembly checklist to verify that ail
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. The skid shoes are factory adjusted for clearing a smooth surface. {Refer to the Service and Adjust ments section in this manual.)
• Make sure the tractor engine has the correct oil for
winter operation. Refer to your tractor owner's manual.
UPPER AND LOWER DISCHARGE CHUTE Controls
direction and height of snow discharge.
SCRAPER PLATE Replaceable plate that absorbs
wear and impact from contact with ground.
SKID SHOE Controls amount of clearance between
the scraper plate and the ground.
SPIRAL AUGER, R.H. & L.H. Feed snow to the
impeller fan at the center of the housing.
HOW TO START YOUR SNOW THROWER
• The tractor should be sitting with the engine running at full throttle. Puli the attachment clutch switch out
to the engaged position, starting the snow thrower
before starting the tractor in motion.
HOW TO STOP YOUR SNOW THROWER

CONTROLLING SNOW DISCHARGE

• To control the direction snow is thrown, the dis charge chute has 180 degrees of rotation. Turn the crank rod ciockwise to rotate the chute to the right. Turn the crank rod counterciockwise 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 iower, push down slightly on the lift handle and pull the trigger. With the trigger pulled, slowly iower the snow thrower until it reaches the ground.
ailow anyone in front of unit.
In extremely deep snow, raise the snow thrower from the ground to remove the top iayer and drive forward only until the tractors front tires reach the
uncleared bottom iayer of snow. Depress the tractor's clutch-brake 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.
Unciog the snow thrower before resuming opera tion.
DANGER; Shut off engine and
disengage snow thrower before

OPERATING TIPS
CAUTION: Do not operate the snow
thrower without the rear weight attached
A

REMOVING SNOW

Snow removai 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, sieds, 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 ailow 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.
to the tractor to provide extra traction and stability.
• Discharge snow down wind whenever possible.
• To help prevent snow from sticking to the snow thrower, ailow 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 ail 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.

• The spiral augers are secured to the auger shaft with two shear bolts and hex lock 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 22. Two replace ment shear bolts and hex lock nuts have been provided with the snow thrower. For future use order part number 710-0891 shear bolt and number 43064 hex lock nut.
SKID SHOE, LEVELING SHOE ADJUSTMENT
(The snow thrower must be attached to the tractor for
correct adjustment of the shoes.)
• The skid shoes regulate the distance the scraper plate is raised above the plowing surface. They are mounted on each side of the spiral auger housing.
The leveling shoes help maintain the snow thrower
in a level position. They are mounted Just behind
the auger housing.
• When removing snow from a gravel driveway or an 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 a smooth blacktop or concrete surface, keep the scraper plate as close to the surface as possible.
• To adjust the skid shoes, raise the snow thrower off
the ground and place a wood 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 to the desired position and
tighten the nuts securely. Both skid shoes should
be the same height to keep the housing and the scraper plate level. See figure 23.
• The skid shoes may be turned to face either in or
out. In order to obtain the lowest setting, where the
scraper blade fully contacts the ground, the skid shoes must be facing out as shown in figure 23.
• Before adjusting the leveling shoes, make sure the skid shoes are properly adjusted. With the snow
thrower in the lowered position, loosen the bolts which fasten the leveling shoes to the thrower and
adjust the leveling shoes to solidly contact the ground. Retighten the bolts. See figure 23.

STORAGE RECOMMENDATIONS
• Lower the snow thrower to the ground and remove it from the tractor.
• Clean the snow thrower thoroughly. Wash off any salt deposits which may have dried on the thrower and housing.
• Any bare metal that has become exposed should be painted or coated with a iight oil to prevent rust.
• Store in a dry place.
REMOVING THE SPIRAL AUGER HOUSING
• Raise the snow thrower to the transport position.
• 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/idier assembly. See figure 18 on page 11.
• Lower the snow thrower to the ground.
• Remove the attachment pin and puli the auger housing assembly off of the tractor. Refer to figure 15 on page 10.
HINT: If the auger housing does not remove easily
from the tractor, try placing 1" or 2" blocks of wood under the front skid shoes on the snow thrower.
See the instructions for figure 15 on page 10.
PARTS TO REMOVE AT END OF SEASON
• Remove the "V" belt from the engine pulley and the clutch/idler assembly. See figure 16 on page 10.
• Remove the clutch/idier assembly. (The two hanger
brackets and the two frame brackets should not
create any interference with the mower deck and
may be left attached to the tractor frame.)
• If a rear mounted attachment is to be used, remove the rear weight tray by removing the two bolts which fasten it to the tractor draw bar and by
loosening the two bolts fastening the tray's brace arms to the tractor. Be sure to retighten the two bolts and nuts which fastened the brace arms to
the tractor. See figure 19 on page 12.
• If a front mounted attachment is to be used,
remove the side plates from the front of the tractor. Be sure to reassemble the removed bolts and nuts
to the tractor frame. See figures 1 and 2 on page 6.
