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.
•
•
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 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 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.

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 dis-
charge 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.

•
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.
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.
•
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 opera-
tion.
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.
DANGER: Shut off engine and
disengage snow thrower before
unclogging discharge chute. Unclog
using a wooden stick, not your hands.
•
Before beginning operation, thoroughly inspect the
area of operation and remove all door mats, sleds,
boards, wires and other foreign objects.
OPERATING TIPS
•
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.
•
•
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.
•
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.
•
•
•
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.

Remove the attachment pin.
Lock the snow thrower's lift handle in the down
position to decrease belt tension.
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 figure 13 on page 9.
•
•
•
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 30 on page 15.
Assemble the belt onto the clutch/idler assembly.
Refer to figures 31 and 32 on pages 15 and 16.
•
Place the attachment clutch lever in the disen-
gaged position.
•

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 pos-
sible.
SPIRAL AUGERS
•
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 38. Two replace-
ment 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.
•
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 37.
