Maintenance Instructions

ADJUSTMENTS

Blade Clutch (PTO)

Clutch Engagement/Belt Tension

The clutch engagement and PTO belt tension are adjusted using the clutch actuator rod. Initially, after installing a new PTO belt, after 10 hours and every 100 hours thereafter, check and adjust for the two dimensions in the clutch actuator rod as shown in the PTO Clutch Engaged and PTO Clutch Disengaged illustrations.

Adjust the bolt head clearance [1/4 in. to 3/8 in. (6.35 mm to 9.53 mm)] first (clutch engaged), then adjust uncompressed spring length (clutch dis- engaged). The spring must be adjusted to an un- compressed overall length of 2 in. (51 mm). If adjustments are needed more frequently than every 100 hours to maintain the linkage dimensions, it may suggest problems with pulley wear or belt misalign- ment.
