2. Never allow children to operate equipment. Never
allow adults to operate equipment without proper
instruction.
3. Keep the area of operation clear of all persons, es
pecially small children and pets.
4. Exercise caution to avoid slipping or falling, es
pecially when operating in reverse.
PREPARATION
1. Thoroughly inspect the area where the equipment
is to be used and remove all door mats, sleds,
boards, wires and other foreign objects.
2. Disengage all clutches and shift into neutral before
starting engine or motor.
3. Do not operate equipment without wearing ade
quate winter outer garments. Wear footwear which
will improve footing on slippery surfaces.
4. Handle fuel with care, it is highly flamamble.
(A) Use approved fuel container.
(B) Never add fuel to a running engine or hot en
gine.
(C) Fill fuel tank outdoors with extreme care. Never
fill fuel tank indoors.
(D) Replace gasoline cap securely and wipe up
spilled fuel.
(E) Open doors if engine is run in the garage—ex
haust fumes are dangerous.
5. Adjust coilector housing height to clear gravel or
crushed rock surface.
6. Never attempt to make any adjustments while en
gine or motor is running (except where specifically
recommended by manufacturer).
7. Never operate the snow thrower without good vis
ibility or light.
8. Let engine and machine adjust to outdoor tempera
tures before starting to clear snow.

OPERATING INSTRUCTIONS
This snow thrower is capable of handling heavy
snow conditions. If given the opportunity to function
within reasonable requirements it should give many
years of service. Become fully familiar with all aspects
of both the lawn tractor and snow thrower prior to
its usage.
BEFORE PLACING SNOW THROWER INTO OPERATION
1. Check all nuts and bolts for correct tightness
and be sure that ail parts are properly assembled.
2. Test all controls for smooth operation.
A. Lift lever
B. Discharge chute control crank
C. Discharge chute and deflector
3. Starting and stopping snow thrower.
The snow thrower is driven by a V-belt driven from
the lawn tractor engine. It is operated through the
lift disengagement handle. Start lawn tractor engine
and run at full throttle. Slowly engage (push forward)
the lift handle.
To stop snow thrower operation, pull the lift handle
towards you and lock handle.
DISCHARGE CHUTE CONTROL CRANK
The discharge chute control crank is located on left
hand side of lawn tractor. Turn crank to the right to
direct snow to the right hand side. Turn it to the left
to direct snow to left hand side.
TO RAISE AND LOWER SNOW THROWER
Lift lever to raise and lower snow thrower is located
on the right hand side of lawn tractor. To raise snow
thrower pull back on lift lever until it reaches over
center stop. To lower snow thrower, push lift lever
forward slowly until snow thrower reaches gcound
level.
When snow thrower and lawn tractor
are not in use, lower snow thrower to
ground lever. This will prevent excess
weight on the front tires.
OPERATING ADJUSTMENTS
A
When making skid shoe or chute
- deflector adjustment, turn rider enengine off.
Upper Chute Deflector: The upper chute deflector
mounted on the top of the chute determines the
distance snow is thrown. Moving top of deflector
down decreases distance of throw and raising deflector
increases distance of throw. Operator must get off
lawn tractor to make this adjustment. Disengage
spirals (by raising snow thrower) before making this
adjustment.
SKID SHOE ADJUSTMENT (See Figure 24)
The skid shoes are mounted on each side of spiral
housing. These regulate the distance the shave plate
is raised above the plowing surface. When removing
snow from a gravel driveway or an uneven surface, it
is advisable to keep shave plate as high above the
surface as possible to prevent possible damage to
spiral.
CAUTION
PREPARATION
1. Check the lawn tractor and thrower to make
certain both are in good operating condition.
2. Fill gas tank out of doors and avoid spilling
gasoline over engine. Do not fill tank while
engine is running. Wipe up any spilled gas.
3. Do not remove any guards or covers while
operating lawn tractor and thrower.
Snow thrower chute has a discharge radius of 180
degrees. Adjust discharge by turning the chute crank.
SKID SHOE
12 FIGURE 24
Page 13
On blacktop or concrete surface, keep shave plate
as close to the surface as possible. Skid shoes can be
adjusted so that shave plate will rest directly on the
surface. Turning skid shoes around will allow even
wear on skid shoes.
Raise snow thrower off the ground and place a block
at each end of shave plate. Loosen 4 nuts securing
skid shoes to spiral housing (2 nuts on each side).
Move skid shoes up or down to desired position and
tighten nuts securely. Adjust both skid shoes to the
same height to keep spiral level. See figure 24.
OPERATION
The thrower controls are conveniently located at the
operator's position on the lawn tractor. By engaging
the lift handle to the spiral, snow is thrown through
chute by the motion of the spiral. Turning chute
crank directs snow discharge and deflector controls
distance snow is thrown.
A
If snow thrower becomes plugged with
snow, or jammed due to hitting a
foreign object, disengage snow thrower
immediately and stop lawn tractor
engine. Clear snow from chute if
plugged, before resuming operation.
CAUTION
OPERATING SPEED
The spiral speed is directly related to engine speed.
For maximum snow removal and discharge, maintain
high engine R.P.M. (full throttle). The lawn tractor's
forward speed is controlled by selecting one of the
forward speeds. It is advisable to operate the lawn
tractor at a slow ground speed (1st gear) for safe
and efficient snow removal.
DEEP OR DRIFTED SNOW
In deep, drifted, or banked snow, it will be nec
essary to use full throttle and first speed. Drive the
spiral into the snow, disengage clutch and allow spiral
to clear the snow. Repeat this method until a path is
cleared. On the second pass, overlap the first enough
to allow the spiral to handle the snow without repeated
clutching and declutching of the lawn tractor.
In extremely deep snow, raise thrower from the
ground, drive lawn tractor ahead in the deep snow to
remove top layers first. Do not drive lawn tractor into
snow bank where snow has not been removed to
ground level. Disengage lawn tractor clutch and allow
thrower to clear the snow. Reverse lawn tractor and
lower thrower to the ground. Drive lawn tractor
ahead and repeat process to remove balance of snow.
Working with repeated passes into and out of drifts
will eventually move even the deepest of snow piles.
NOTE
If spiral is jammed or bent from hit
ting a foreign object, stop lawn tractor
engine. Remove spark plug wire from
spark plug and then remove foreign
object from spiral. If spiral damage
is noted, repair prior to continuing
operation. Then replace spark plug
wire and resume operation.
SNOW CONDITIONS
Snow removal conditions vary greatly from light
fluffy snowfall to the wet heavy snow. Therefore,
operating instructions must be flexible to fit conditions
encountered. The operator must adapt the lawn
tractor and snow thrower to depth of snow, wind
direction, temperature, and surface conditions.
OPERATING TIPS
1. Whenever possible discharge snow down wind.
2. Do not attempt to remove ice or hard packed
frozen snow.
3. Always overlap each pass slightly to assure
conhplete snow removal.
4. A frozen or stuck spiral or chute must be broken
loose or thawed with care. When attempting to
loosen frozen or jammed spiral, shut off rider
engine and remove spark plug wire. Never attempt
to clear snow thrower at any time with lawn
tractor engine running.
USE OF TIRE CHAINS
Tire chains should always be used when extra
traction is needed. They add maneuverability in
13 handling snow removal jobs.
Page 14
LUBRICATION
1.
Spiral drive chain: Lubricate chain every 40
operating hours with No. 30 oil. It is important
that oil reaches inside each roller. Wipe off excess
oil from chain.
2.
Pivot and friction points: To maintain smooth
and free operation, apply a few drops of No. 30
oil as required to all pivot and friction points.
The spiral and idler pulley bearings are self-lubricating.
However, periodic lubrication with No. 30 oil will
lengthen service life.
SPIRAL DRIVE CHAIN ADJUSTMENT
Periodically check spiral drive belt to insure that it is
properly adjusted. It is important to maintain proper
belt adjustment to obtain maximum belt life.
If belt is stretched beyond idler take up, replace with
a new belt of the type specified in parts list.
Excessive slack in spiral drive chain due to normal
chain stretch can be removed by adjusting spiral
housing nuts.
TO ADJUST SPIRAL CHAIN:
1. Disengage snow thrower and loosen the mounting
nuts 2 or 3 complete turns.
2. Tighten the adjustment mounting nuts to tighten
chajn.
BELT TENSION ADJUSTMENT
The idler bracket has three holes for belt tension
adjustment. As the belt stretches from normal wear,
more belt tension may be required. Check the idler
spring for wear against the drive shaft at least once a
season. If the idler spring is rubbing against the drive
shaft, the belt has stretched and must be adjusted.
Remove the idler pulley from the bracket, and
reassemble in next lower hole on the bracket.
STORAGE
At the end of the snow season the following steps
are recommended:
1. Remove snow thrower assembly from lawn tractor
tractor.
2. Wash off any salt deposit which may have dried
on the thrower and housing. Paint or cover
exposed metal with a light coat of oil.
3. Lubricate thrower following lubricating in
structions for recommended lubricant. Thrower
drive chain must be oiled thoroughly to prevent
rust from forming. The preferred method is to
remove the chain and soak in oil for several hours
before reinstalling.
4. Store thrower in a dry place.
CAUTION
Do not over tighten chain. A correctly
adjusted chain will have a slight
amount of slack. An over tightened
chain will result in early failure of
chain.
3. Tighten mounting nuts to securechain adjustment.
Check chain clearance. It must clear chain guard
assembly. Test chain and repeat adjustment if
necessary until all excess slack is removed.
SHAVE PLATE AND SKID SHOES
Both the shave plate and skid shoes are subject to
wear and are designed to be easily replaced. Replace
before wear is excessive. Failure to do so will result
in damage to the spiral housing.
