SECTION5: CONTROLS
_ ARNING: Be familiar with all controls and
their proper operation. Know how to stop the
machine and disengage them quickly.
EngagingtheAugersandImpeller
Power to the snow thrower attachment is activated by
engaging the tractor's PTO.
• Place the tractor's throttle control in the FAST
(rabbit) position and allow it to remain there for
efficient snow removal.
• Move the PTO knob intothe "ON" position to
engage the augers and impeller.
• Move the PTO knob into the "OFF" position to
disengage the augers and impeller.
NOTE: The PTO knob (on units so equipped) cannot
be in the engaged (ON) position when the tractor is
driving in the reverse direction. The PTO knob must be
in the disengaged (OFF) position when the shift lever is
placed in REVERSE or the electric PTO clutch will
automatically shut off.
14
NOTE: The PTO lever (on units so equipped) cannot
be in the engaged (ON) position when the tractor is
driving in the reverse direction. The PTO lever must be
in the disengaged (OFF) position when the shift lever is
placed in REVERSE or the tractor's engine will
automatically shut off.
Refer to your tractor's Operator's Manual for more
information regarding your tractor's PTO and safety
interlock system.
Lift Handle
The lift handle is located on the right side of the tractor
and is used to raise and lower the snow thrower
attachment.
• To raise the snow thrower attachment off of the
ground, pull rearward and down on the lift handle
until you feel the lift latch on the right side of the
snow thrower engage, locking the snow thrower in
a raised position.
To lower the snow thrower, push downward on the
lift handle until there is enough slack in the lift cable
so that you may squeeze the trigger control. With
the trigger control squeezed, gently allow the snow
thrower to lower until it reaches the ground.
ChuteDirectionalControl
The chute directional control assembly is found on the
left side of the tractor and includes both the chute tilt
lever as well as the chute crank. Both affect the
direction that the discharged snow is thrown.
• To pivot the upper section of discharge chute,
affecting the distance and angle which the snow is
thrown, move the chute tilt lever forward or
rearward into a desired position.
• The direction which snow is thrown can be changed
by rotating the discharge chute with the chute
crank. Turn the chute crank clockwise to rotate the
chute and discharge snow to the left. Crank it
counterclockwise to rotate the chute and discharge
snow to the right.

,_ WARNING: Read, understand, and follow all instructions and warnings on the tractor, attachment, and
in the Operator's Manuals before operating.
Your snow thrower attachment is capable of displacing snow and clearing a path a width of 42 inches.
Observe the following operating instructions for efficient snow removal.
• Become familiar with and comfortable using all of
your tractor's controls as instructed in your tractor's
Operator's Manual before operating it with the snow
thrower attachment.
• Make certain the correct weight (and volume) of
motor oil in is your tractor's engine as instructed in
the tractor's Operator's Manual.
• Always operate the snow thrower with the tractor's
engine at maximum RPM (full throttle).
• NEVER override any safety features on either your
tractor or the snow thrower attachment.
• Make certain that all nuts, bolts, and hardware are
fastened securely and tight on both the tractor and
the snow thrower attachment prior to use.
• Make certain the snow thrower is assembled
properly and mounted to the tractor as instructed in
this manual.
• Test all the controls (tractor PTO, snow thrower lift
handle, chute tilt lever & chute crank) for smooth
operation prior to operating the snow thrower in
snow.
• Make all adjustments (i.e. skid shoes, lift latch)
before operating your snow thrower attachment.
Follow instructions in the Adjustments section of
this manual when doing so.
• Engage the tractor's PTO to activate power to the
augers and impeller BEFORE driving the tractor
forward and into snow.
• Keep your tractor's ground-speed slow. The slower
your tractor is traveling, the more effectively the
snow thrower attachment can displace snow.
• Adjust ground speed for snow conditions and
become familiar with different snow applications.
Your snow thrower attachment will operate
differently in wet heavy snow than it will it light, fluffy
snow.
• Overlap a previously cleared path when necessary
(deep snow) so as not to overload the auger
housing with snow.
• NEVER drive the tractor into a snow bank. The
snow thrower attachment is not a dozer plow. The
lift linkage and/or the snow thrower drive system
can be damaged as a result of "plowing" with the
snow thrower attachment.

SECTION7: MAKINGADJUSTMENTS
_ ARNING: Never attempt to make any
adjustments while the engine is running,
except where specified in the Operator's
Manual. Place tractor on a firm and level
surface. Place the PTO in the disengaged
(OFF) position, set the parking brake, shut
engine off, and remove key to prevent
unintended starting.
LiftAdjustment
If the lift index rod doesn't latch securely or the pivot
release has too much slack in it, an adjustment can be
made as follows:
• Loosen the upper hex nut a few turns, then tighten
the lower hex nut to shorten the cable length. See
Figure 19.
• Loosen the lower hex nut a few turns, then tighten
the upper hex nut to lengthen the cable. See Figure
19.

LowerChuteCrank
SupportBracketAdjustment
If the spiral at the base of the lower chute crank isn't
fully engaging with the notches in the lower chute
assembly, the support bracket can be adjusted inward
or outward as follows:
• LohoS "sebcUtr"e h eOT;;:2 eatc"ke ot ex uts
thrower houiing. See Figure 20. i_
iral
Rex Nut ,_ _r ,_ Supper[Bracket
Figure 20
• Adjust the support bracket inward or outward so
that the spiral is fully engaged in the notches on the
chute before retightening the hex nuts.
SkidShoeAdjustment
The space between the shave plate and the ground can
be adjusted by repositioning the skid shoes found on
either side of the snow thrower's auger housing. For
close snow removal, place skid shoes in the low
position. Use a middle or high position when the area to
be cleared is uneven.
IMPORTANT: It isNOT recommended that this snow
thrower be operated on a gravel surface, as loose
stones can be easily picked up and thrown by the
machine. If you must operate on a gravel surface,
ALWAYS adjust the skid shoes into the HIGH position
to allow the shave plate maximum clearance.
Adjust skid shoes as follows:
• Loosen, but do NOT remove, the three hex nuts
which fasten the skid shoe to the auger housing.
See Figure 21.
• Raise or lower the skid shoe to desired position.
NOTE: Make certain the entire base of both skid
shoes are against the ground to avoid uneven wear on
the skid shoes. When one side does wear out, the skid
shoes are reversible.
• Retighten the hex nuts loosened earlier.
• Repeat this adjustment on the skid shoe found on
the opposite side of the snow thrower.

SECTION8: MAINTENANCE
_b efore lubricating, repairing, or inspecting,
place tractor on a firm and level surface. Place
the PTO in the disengaged (OFF) position, set
the parking brake, shut engine off, and remove
key to prevent unintended starting.
Lubrication
ChuteDirectionalControl
The spiral on the end of the lower chute crank, the base
of the discharge chute itself and the joint blocks which
connect the lower and upper chute cranks should be
lubed with multi-purpose automotive grease once a
season. See Figure 22,
AugerShaft
• At least once a season, remove the shear bolts on
the auger shaft. Oil or spray lubricant inside and on
the plastic bearings on the shaft and near the holes
where the shear bolts were removed before
reattaching them. See Figure 23.
