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.

• Keep the area of operation clear of all persons, especially
small children, and pets.

• Thoroughly inspect the area where the equipment is to
be used and remove all door mats, sleds, boards, wires
and other foreign objects.

• Disengage all clutches and shift into neutral before

starting engine.

• Do not operate equipment without wearing adequate
winter outer garments.

• Wear substantial footwear which will protect feet and
improve footing on slippery surfaces.

• Check fuel before starting the engine. Do not remove the
fuel cap or ll the fuel tank while the engine is running
or hot. Do not ll the fuel tank indoors. Gasoline is an
extremely ammable fuel.

• Make sure the snow thrower height is adjusted to clear
the type surface it will be used on.

• Do not use the snow thrower without the rear weight
attached to the tractor.

• Never make any adjustments while the engine is

running.

• Always wear safety glasses or eye shield during operation
or while performing adjustment or repair.

• Do not place hands or feet near rotating parts. Keep
clear of the discharge opening at all times.

• Use extreme caution when operating on or crossing

gravel surfaces.

• Do not carry passengers.

• After striking a foreign object, stop the engine, remove
the wire from the spark plug and then thoroughly inspect
the snow thrower for damage. Repair any damage before
restarting and operating the snow thrower.

• If the snow thrower starts to vibrate abnormally, stop the
engine immediately and check for the cause. Vibration
is generally a warning of trouble.

• 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 transporting 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 79 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 enclosures,
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 attempting 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 up.

• Watch for trafc and stay alert when crossing or operating
near roadways.

• Disengage power to the snow thrower when transporting
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.

IMPORTANT:

Rear wheel weights and tire chains are required to
provide extra traction and stability when using this
snow thrower attachment. These items are available

where you purchased your tractor.

suspension bracket underneath the middle of the
front axle, skip to step 21 on page 14 for tractors

with dual suspension brackets.

CAUTION: Before starting to assemble the

snow thrower, remove the spark plug wire(s),
set the parking brake and remove the key
from the tractor ignition.

TRACTOR PREPARATION

Before performing these instructions, refer to the Service
and Adjustments section of your tractor owner's manual
for specic safety instructions.

• Allow engine, mufer and exhaust deector to cool
before beginning.

• Remove any front or rear attachment which is
mounted to your tractor.

• Remove the mower deck. Refer to your tractor owner's

manual for removal instructions. Mark all loose parts
and save for reassembly.

• Tilt the snow thrower back down to the ground.

• Remove the nylon tie which fastens the auger
drive belt to the discharge housing, leaving the belt
assembled around the pulleys.

• Remove the nylon tie which fastens the chute crank
rod to the crank rod support tube.

• Assemble the crank rod support tube to the bracket
on the left side of the discharge housing using two
5/16" x 1-1/4" carriage bolts (I), and 5/16" Nylock nuts

(Y).

NOTE: Be sure the lift release cable's plastic covering
stays inserted into the trigger assembly for the next step.

STEP 49: (SEE FIGURE 48)

• Push the lift handle down into the locked position.

HINT: For easier assembly of the lift release cable, tilt the
snow thrower forward onto the spiral auger.

Insert the end of the cable wire into the hole in the
lift rod. Place the threaded tting into the slot in the
lift bracket, with one hex nut above and one hex nut
and the lock washer below the slot. Tighten the nuts,
adjusting them to eliminate slack in the cable wire.
Refer also to the Service and Adjustments section on
page 28 in this manual.

• Attach the chute crank rod assembly brackets to
the plastic bracket on the left side of the discharge
housing. Align the chute crank bracket beneath the
rod support bracket and assemble both to the plastic
bracket using two 5/16" x 1" carriage bolts (J), 5/16"
washers (Q) and 5/16" Nylock nuts (Y). Do not

tighten yet.

STEP 53: (SEE FIGURE 52)

• Coat the top of the ring around the discharge opening
with general purpose grease.

• Place the discharge chute (facing forward) onto the
ring. Place the anti-rotation bracket on top of the chute
ange, aligning it with the holes on the right hand side
of the ange. Attach the three chute keepers (BB)
(right side up as shown) to the bottom of the ange
using six 1/4" x 1" hex bolts (D), 1/4" at washers (P)
and 1/4" anged lock nuts (V). Tighten carefully so
that the nuts are snug but do not dig into the plastic
chute keepers.

• Place the plastic cap (HH) onto the short end of the
anti-rotation bracket.

• Position the crank rod spiral (see gure 51) so that it
does not rub against the bottoms of the notches in the
chute ange. Tighten the nuts.

• Check if the crank rod rotates the chute freely. If not,
loosen by 1/4 turn each of the six hex bolts holding
the chute keepers to the chute ange.

• Secure the control cables to the crank rod support
tube using a nylon tie (II).

STEP 55: (SEE FIGURE 54)

• Place the tractor and snow thrower on a at, level
surface so that the tractor can be rolled forward to
attach the snow thrower.

• Remove the Attachment Pin from the snow thrower.

• Extend the auger belt out behind the snow thrower,
making sure the belt is still looped over the top of
the large drive pulley and underneath the two idler
pulleys. The "V" side of the belt must be seated in the
grooves of all three pulleys.

• Roll the tractor up behind the snow thrower, centering
it between the snow thrower's mounting plates.

• Raise the rear of the snow thrower by lifting up on
the lift handle until the notches in the mounting plates
align with the shoulder bolts in the tractor's side
plates. Guide the bolts into the notches.

• To ease the assembly of the auger drive belt, delay
the installation of the attachment pin until you have
assembled the belt as instructed in steps 56 and 57.

BEFORE INSTALLING THE AUGER BELT

STEP 56: (SEE FIGURE 55)

• The auger belt comes preassembled to the pulleys on
the snow thrower housing. Make sure the belt passes
over the top of the auger pulley and then twists 1/4
turn to pass underneath each side idler pulley. The
"V" side of the belt must mate with the grooves of the

pulleys.
