MULE DRIVE BELT ADJUSTMENT

5.2.5Deck Belt Tension.

a)The deck belt is tensioned by a self-tensioning idler, no adjustment is necessary.

5.2.6Adjust Seat Switch

a)If necessary, adjust the seat actuator rod length to where the machine will shut off when the operator raises off the seat (with brake disengaged or PTO engaged) but will continue to run with operator in seat (a slight shift in weight should not shut machine off).

Normal adjustment is when length of spring is 2.09” (5.3 cm) (with seat up).

NOTE: To prevent the engine from cutting out when operating over rough ground, the unit is equipped with a time-delayed seat switch. When the operator raises off the seat with either the brake disengaged or the PTO engaged, the engine should stop after 1/2 second has elapsed.

b)To adjust seat switch actuator rod length, loosen lock nut on bottom of the actuator rod (5/16 x 7” bolt) and adjust the nuts to move the actuator plate/washer up or down on the rod, then retighten.

5.2.7Belt Guide Adjustment.

a)Stop engine, wait for all moving parts to stop, and remove key.

b)Remove the belt shield on the right side of mower deck.

c)Note belt guide bolted to deck near the shield support stud and right-hand pulley. Guide should be 1/8” (3.2 mm) away from the belt, with bolt-end of guide near end of slot (See Figure 13).

d)If adjustment is necessary, loosen the bolt securing the belt guide and make proper adjustment. Tighten hardware.
