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 fi ll the fuel tank while the engine is running
or hot. Do not fi ll the fuel tank indoors. Gasoline is an
extremely fl ammable 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 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 27 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.
•
Watch for traffi c 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.

BEFORE STARTING
1.
Use the end of assembly checklist to verify that all
instructions have been properly completed.
2. 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.)
3. 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
1.
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's
transmission is engaged.
HOW TO STOP YOUR SNOW THROWER
1. 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.
CAUTION
: Never
direct discharge
towards bystanders or windows. Do not
allow anyone in front of unit.
CONTROLLING SNOW DISCHARGE
1. 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.
2. 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
3. To raise, push down on the lift handle until the snow
thrower locks in the raised transport position.
4. 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 rear wheel weights and tire
chains attached to the tractor to provide
extra traction and stability.
DANGER
:
Shut off engine and
disengage snow thrower before
unclogging discharge chute. Unclog using
a wooden stick, not your hands.
REMOVING SNOW
Snow removal conditions vary greatly from light fl uffy snowfall
to wet heavy snow. Operating instructions must be fl exible
to fi t the conditions encountered. The operator must adapt
the lawn tractor and snow thrower to depth of snow, wind
direction, temperature and surface conditions.
5. Before beginning operation, thoroughly inspect the area
of operation and remove all door mats, sleds, boards,
wires and other foreign objects.
6. 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 effi cient snow removal.
7. 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 fi rst enough to allow the snow thrower to
handle the snow without repeated stopping and starting
of forward motion.
8. 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 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.
9. 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.
OPERATING TIPS
1. Discharge snow down wind whenever possible.
2. 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.
3. Use tire chains to improve traction.
4. Use rear wheel weights to improve traction.
5. Before the fi rst snowfall, remove all stones, sticks and
other objects which could become hidden by the snow.
Permanent obstacles should be marked for visibility.
6. Overlap each pass slightly to assure complete snow
removal.
LUBRICATION
1.
Oil all pivot points on the snow thrower.
2. Oil the pivot points of the two idler arms on the clutch/idler
assembly.
3. Apply penetrating oil to the control cables of the discharge
chute.
4. Apply a good grade of spray lubricant to the trigger
assembly and the chute tilt control assembly.
CHECK SCRAPER AND SHOES FOR WEAR
(Refer to fi gures 34 and 35 on page 19.)
5. 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.

REPLACING AUGER BELT
1. Disengage the tractor's attachment clutch.
2.
Lower the snow thrower to the ground.
3. Remove the attachment pin.
4. Lock the snow thrower's lift handle in the down position
to decrease belt tension.
5. Release the spring tension from the auger belt idler arm
on the bottom of the clutch/idler assembly.
6. Remove the auger drive belt from the clutch/idler
assembly and from the spiral auger housing.
7. 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 fi gure 30 on page 15.
8. Assemble the belt onto the clutch/idler assembly. Refer
to fi gures 31 and 32 on pages 15 and 16.
SKID SHOE ADJUSTMENT
1. 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.
2. 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 fi gure 34.
LIFT RELEASE CABLE ADJUSTMENT
1. 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 fi gure 24 on page 13.
2. 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 fi gure
24 on page 13.
CLUTCH DISENGAGEMENT ADJUSTMENT
(Only tractors with clutch engagement rods.)
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 fi gure 13 on page 9.
1. Place the attachment clutch lever in the disengaged
position.
2. Remove the hairpin cotter from the engagement rod
trunnion and lift the trunnion out of the hole in the idler
arm.
3. Screw the trunnion a few turns towards the front end of
the rod.
4. 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
1. 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.
2. If the augers will not turn, check to see if the shear bolts
have sheared. See fi gure 35. Two replacement shear
bolts and hex lock nuts have been provided with the snow
thrower. For future use order part number 710-0890A
shear bolt and number 43064 hex lock nut.
