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. 9), cable operated (p. 10) or electric (p. 12).
Use the appropriate instructions for your tractor.
MANUAL (ROD OPERATED) ATTACHMENT CLUTCH
1. Move the attachment clutch lever on the dash panel to
the disengaged (down) position.
2. Screw the trunnion onto the end of the snow thrower
engagement rod as shown in fi gure 11.
3. 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.
4. 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. See fi gure 11.
5. Be sure to lift up the front end of the engagement rod (as
shown in fi gure 12) when performing the next operation.
You can temporarily support the rod using a rubber band
tied to the engine pulley keeper.
6. Attach the clutch/idler assembly to the tractor frame as
follows. Hook the assembly's notched arms onto the two
shoulder bolts you assembled to the inside of the tractor
frame. Lift the front of the assembly and attach it to the
R.H. and L.H. hanger brackets using two pivot lock pins
and 1/8" hairpin cotters. See fi gure 12.

7. Make sure the attachment clutch lever on the dash panel
is in the disengaged (down) position.
8. Pivot the upper idler arm so that it rests against the
stop bolt and is pointing toward the front as shown in
fi gure 13. Screw the trunnion along the threads of the
engagement rod until it is aligned at the front end of the
idler arm slot. Attach the trunnion to the slot using the
3/8" fl at washer and a 5/64" hairpin cotter. See fi gure
13.
9. Remove the engine pulley keeper from the side of the
tractor frame by removing the washer and nut that secure
the keeper. Attach the new pulley keeper supplied with
the snow thrower, reusing the original bolt, washer and
nut. See fi gure 13.
NOTE: Some tractors may already be equipped with an
identical pulley keeper.
