Do not place hands near rotating parts. Keep clear of the
discharge opening at all times.
Do not place feet near rotating parts.
• Never allow children to operate the equipment.
• Never allow adults to operate the equipment without
proper instruction.
• 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.
• 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 run the snow thrower into snow at high speeds.
• Do not overload the snow thrower capacity by
attempting to clear snow at too fast a rate.
• Never operate the snow thrower 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.

BEFORE STARTING
HOW TO USE YOUR SNOW THROWER
• 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.
CAUTION: Never direct discharge
towards bystanders or windows. Do not
allow anyone in front of unit.
HOW TO START YOUR SNOW THROWER
CONTROLLING SNOW DISCHARGE
• To control the direction snow is thrown, the discharge
chute has 180 degrees of rotation. Turn the crank rod
to rotate the chute to the right or the left.
HOW TO STOP YOUR SNOW THROWER
• 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.
• 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.
• 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.
18
• In extremely deep snow, raise the snow thrower up
to the transport position to remove the top layer of
snow. Drive forward only until the front tires reach
the uncleared bottom layer of snow. Stop and allow
the snow to clear out of the spiral auger. Back up
and then 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.
Use a wooden stick to unclog the snow thrower before
resuming operation.
RAISING AND LOWERING
• Use the toggle switch attached to the side of the
tractor's dash to raise or lower the snow thrower. The
winch motor will shut off when the snow thrower is in
either the up or down position.
CAUTION: Do not operate the snow
thrower without rear wheel weights
attached to the tractor to provide extra
traction and stability.
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 AND ADJUSTMENTS
CAUTION: Before servicing or adjusting
• If the augers will not turn, check to see if the shear
bolts have sheared. See figure 34. 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.
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
SHEAR BOLT AND
HEX LOCK NUT
• Disengage the tractor's attachment clutch.
• Lower the snow thrower to the ground.
• 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 29 on page 16.
• Assemble the belt onto the clutch/idler assembly.
SCRAPER PLATE
ADJUSTING SKID SHOES
GEAR HOUSING
SKID SHOE
FIGURE 34
• The skid shoes regulate the distance between the
scraper plate and the plowing surface. When removing
snow from a gravel driveway or and uneven surface,
keep the scraper plate as high above the surface as
possible to prevent possible damage to the spiral
auger. On a 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 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 33.
ADJUSTING LIFT HEIGHT, LEVELING
The snow thrower is equipped with two threaded lift
links for adjusting the lift height and leveling of the snow
thrower in the raised position.
The maximum lift height is approximately 4 inches ground
clearance for GT tractors and 3 inches for YT tractors.
TO ADJUST THE LIFT HEIGHT:
• Raise the snow thrower to the highest position.
• Check the clearance between the rear of the idler
bracket and the lift shaft. A minimum 1/16" clearance
in the raised position is necessary to avoid possible
damage to the lift system.
• To increase the lift height, tighten the nuts on the
bottom of both lift links equally until the maximum lift
height is obtained.
TO LEVEL WHEN RAISED:
• If the snow thrower is not level in the raised position,
loosen the nut at the bottom of the lift link on the high
side of the snow thrower until it the snow thrower
is approximately level. It is not critical that the snow
thrower be exactly level in the raised position, it will
level out when it is lowered to the ground.
FIGURE 33
SPIRAL AUGERS
• The spiral augers are secured to the auger shaft
with two shear bolts and nylock nuts. The bolts are
designed to shear if an object or ice jams the augers.
