DEEP OR DRIFTED SNOW
In deep, drifted, or banked snow, it will be necessary
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 tractor.
In extremely deep snow, raise thrower from the
ground, drive tractor ahead in the deep snow to
remove top layers first. Do not drive tractor into
snow bank where snow has not been removed to
ground level. Disengage tractor clutch and allow
thrower to clear the snow. Reverse tractor and lower
thrower to the ground. Drive 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.
A
CAUTION
If snow thrower becomes plugged with
snow, or jammed due to hitting a
foreign object, disengage snow thrower
immediately and stop tractor engine.
Clear snow from chute if plugged,
before resuming operation.
NOTE
If spiral is jammed or bent from
hitting a foreign object, stop 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 oper­
ation. Then replace spark plug wire
and resume operation.
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 com­
plete 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 tractor
engine and remove spark plug wire. Never attempt
to clear snow thrower at any time with tractor
engine running.
NOTE
When snow thrower and tractor are
not in use, lower snow thrower to the
ground. This will prevent excess weight
on front tires.
USE OF TIRE CHAINS
Tire chains should always be used when extra traction
is needed. They add manueverability in handling snow
removal jobs.
ADJUSTMENTS
WARNING t
Stop tractor engine and disconnect
spark plug wire before making any
adjustments, repairs or maintenance
on the snow thrower.
UPPER CHUTE DEFLECTOR
The upper chute deflector mounted on 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 tractor to make this adjustment.
Disengage spirals (by disengaging the P.T.O. lever,
located on the right hand side of tractor) before
making this adjustment.
To adjust, loosen hand knob on the side of chute
deflector and pivot to desired position. Retighten
hand knob. See figure 27.

SKID SHOE ADJUSTMENT
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 spir^k
On blacktop or concrete surface, keep shave plate c.a
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.
