Routing The Upper Drive Belt
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. 3-18. 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.
