SAFETY
Read and understand the operating instructions before using.
Keep the area of operation clear of all persons, especially small children and pets.
Thoroughly inspect the area to be cleared and remove all door mats, sleds, boards,
wires and other foreign objects. Use extreme caution when operating on or crossing
gravel surfaces. Never direct discharge at bystanders or allow anyone in front of the
snow thrower.
Do not place hands near rotating parts. Keep clear of the
discharge opening at all times.
Do not place feet near rotating parts.
• Never allow children to operate the equipment.
• Never allow adults to operate the equipment without
proper instruction.
• 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 wheel weights
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.
• 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 35 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 run the snow thrower into snow at high speeds.
• Do not overload the snow thrower capacity by
attempting to clear snow at too fast a rate.
• Never operate the snow thrower at high transport
speed on slippery surfaces. Look behind and use care
when backing up.
• Watch for traffic 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.

FIGURE 10
STOP
Did you select the correct drive belt for your
tractor? Using the wrong length belt may
cause premature bearing or belt failure.
STEP 10: (SEE FIGURE 10)
• Two different length drive belts are included with your
snow thrower. Use the longer, 56" drive belt (#48138)
on tractors with manual attachment clutches.
• Slightly loosen the hex bolt next to the at idler pulley.
Install the drive belt down between the hex bolt and the
at idler pulley with the at side of the belt against the
pulley. Retighten the hex bolt.
• Loop the belt around the large v-pulley, placing it
between the v-pulley and the hex bolt next to the pulley.
Place the belt to the inside of the other at idler pulley.
FIGURE 8
STEP 8: (SEE FIGURE 8)

FIGURE 11
ATTACH CLUTCH IDLER ASSEMBLY TO TRACTOR
STEP 12: (SEE FIGURE 12)
• Hook the rear of the clutch/idler assembly onto the
two shoulder bolts assembled to the tractor frame. Lift
the front of the assembly and attach it to the R.H. and
L.H. hanger brackets using two clevis pins (OO), six
washers (PP), and two 1/8" hairpin cotters (FF).
• Loosely attach the mower clutch cable to the left side
of the tractor frame with a nylon tie (LL). Do not pull
the nylon tie completely tight. The cable may need to
be removed from the nylon tie when using the mower
deck.
STEP 11: (SEE FIGURE 11)
• Find the cable clip that is attached to the left side
of the tractor frame underneath the footrest. Open
the clip and remove the mower clutch cable. Do not
remove the clip from the tractor frame. The cable
reattaches to the clip when using the mower deck.
• Move the attachment clutch lever on the dash panel to
the disengaged position.
• Place the clutch/idler assembly on the oor on the left
side of the tractor.
• Attach the tractor's mower clutch cable to the cable
bracket on the clutch/idler assembly. Secure the cable
housing guide (groove down) to the cable bracket
using the original collar and a 5/64" hair cotter pin (EE).
• Place the small spacer (II)on the welded pin on the
idler arm. Hook the end of the clutch cable spring
over the pin and secure it with a 1/4" washer (P)and a
5/64" hair cotter pin (EE).
• Align cable bracket with welded pin and tighten the
nut assembled in step 7.

• Assemble the drive belt onto the engine pulley. You
may need to remove the belt from the large pulley on
the clutch/idler assembly in order to assemble it onto
the engine pulley. When re-assembling the belt onto
the large pulley, be sure the belt is between the large
pulley and the hex bolt next to it.

tensioning chain out as far as the 3/32" hairpin cotter
(GG) that was installed in the chain in step 15 will
allow. Secure the chain in this position by inserting a
1/8" hairpin cotter (FF) through the chain.
• Go to step 48 on page 21.

INSTALLING CLUTCH/IDLER ASSEMBLY
This section covers the installation of the Clutch/Idler
assembly to tractors with attachment clutches that are
either rod operated (p. 15), cable operated (p. 17) or
electric (p. 19). Use the appropriate instructions for your
tractor.
ROD OPERATED MANUAL ATTACHMENT CLUTCH
STEP 29: (SEE FIGURE 29)
• Move the attachment clutch lever on the dash panel to
the disengaged (down) position.
• Screw the trunnion (DD) onto the end of the snow
thrower engagement rod (5).
• Locate the clutch arm (where the mower clutch rod
was connected) underneath the right hand side the
tractor, just to the inside of the suspension arm. If
there is an extension attached to the clutch lever, the
extension, bolt and nut must be removed and stored
with the mower deck.
IMPORTANT: Re-attach the extension to the clutch
lever before reinstalling the mower deck.
• Position the engagement rod (5) to the inside of
the clutch arm and insert the drilled end of the rod
through the arm. Secure with a 5/64" hairpin cotter
(EE).

Did you choose the correct drive belt for
your tractor? Using the wrong length belt
may cause premature bearing or belt failure.
STEP 31: (SEE FIGURE 31)
• Two different length drive belts are included with
your snow thrower. Tractors with manual attachment
clutches and dual front deck suspension brackets use
the 55" drive belt with #46989 printed on the outside
of the belt. DO NOT USE the other belt.
• Slightly loosen the hex bolt next to the at idler pulley.
Install the drive belt down between the hex bolt and the
at idler pulley with the at side of the belt against the
pulley. Retighten the hex bolt.
