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 (CC) onto the end of the snow
thrower engagement rod.
• 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 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
(DD).

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 fl at idler pulley.
Install the drive belt down between the hex bolt and the
fl at idler pulley with the fl 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.
