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 39 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.

pulleys.
NOTE: An additional person's help may be required to
mount the snow thrower to the front of the tractor.
STEP 55: (SEE FIGURE 54)
• Place the tractor and snow thrower on a flat, level
surface so that the tractor can be rolled forward to
attach the snow thrower.
• Remove the Attachment Pin from the snow thrower.
• Extend the auger belt out behind the snow thrower,
making sure the belt is still looped over the top of
the large drive pulley and underneath the two idler
pulleys. The "V" side of the belt must be seated in the
grooves of all three pulleys.
• Roll the tractor up behind the snow thrower, centering
it between the snow thrower's mounting plates.
• Raise the rear of the snow thrower by lifting up on
the lift handle until the notches in the mounting plates
align with the shoulder bolts in the tractor's side
plates. Guide the bolts into the notches.
• To ease the assembly of the auger drive belt, delay
the installation of the attachment pin until you have
assembled the belt as instructed in steps 56 and 57.

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.
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.
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.
• 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.
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.
27
• 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.
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.
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
LIFT RELEASE CABLE ADJUSTMENT
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.
• 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.
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.
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.
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 64.
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 65. 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.
