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 Figure 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.
