WARNING
Before installing
attachment, place
tractor on a firm and
level surface. Place
the PTO in the disen-
gaged (OFF) position,
set the parking brake,
shut engine off and
remove key to prevent
unintended starting.
IMPORTANT:
Make certain that the
flat side of the belt is
facing outward. This
allows the "V" side of
the belt to ride snugly
in both pulleys.
Routing the Upper Drive Belt
Spindle Pulley
1. Attach and route upper drive belt around spindle pulley and idler pulley found on undercarriage, electric PTO
clutch and PTO idler pulley as illustrated in Fig. 8-1. Make sure that the belt is routed to the INSIDE of the belt
keeper on the undercarriage idler pulley and the remaining keeper pins found around the spindle pulley.
IMPORTANT: Make certain that the flat side of the belt is facing outward as it sits against both the electric PTO
clutch and spindle pulley. This allows the "V" side of the belt to ride snugly in both pulleys.
Routing the Upper Drive Belt
Spindle Pulley
1. Attach and route the upper drive belt around the engine pulley and spindle pulley, routed to the INSIDE of the
PTO idler pulley on the undercarriage. Make sure the belt is routed inside of the belt keeper pins found around
the spindle pulley and engine pulley. See Fig. 8-2.
IMPORTANT: Be certain flat side of belt is facing outward. This allows "V" side of belt to ride snugly in both pulleys.

idler bracket found beneath the undercarriage, and the drive pulley found on the rear of the snow thrower housing
