MTD TMO-33849A - Manual (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.
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.
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.
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.
A
CAUTION
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.
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
OPERATING TIPS
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.
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.
