Blade Clutch (PTO)

Clutch Engagement/Belt Tension

The clutch engagement and PTO belt tension are adjusted using the clutch actuator rod. After install- ing a new PTO belt, after 10 hours and every 100 hours thereafter, check and adjust for the clutch spring assembly bolt head clearance dimension as shown in the PTO Clutch Engaged illustration. If the clutch actuator rod or clutch spring assembly

have been disassembled, first reset them to their

factory preset lengths (see PTO Clutch Disen- gaged illustration) and then proceed with adjust- ment as follows.

With the clutch engaged, adjust the length of the clutch actuator rod to achieve a clutch spring assembly bolt head clearance of 1/4 in. to 5/16 in. (6.5 mm to 8 mm). To adjust the clutch actuator rod length, loosen both ball joint jam nuts (one ball joint will have LH threads) and shorten the rod to increase the clutch spring assembly bolt head clearance, or lengthen the rod to decrease the bolt head clearance. If adjustments are needed more frequently than every 100 hours to maintain dimensions, it may suggest problems with pulley wear or belt misalignment.
