Maintenance Instructions ADJUSTMENTS
Blade Clutch (PTO)
Clutch Engagement/Belt Tension
The clutch engagement and PTO belt tension are ad-
justed using the clutch actuator link. After installing
new PTO belts, after 10 hours and every 100 hours
thereafter, check and adjust for the clutch spring as-
sembly bolt head dimension as shown in the PTO
Clutch Engaged illustration. If the clutch actuator
link or clutch spring assembly have been disassem-
bled, rst reset them to their factory preset lengths
(as shown in the PTO Clutch Disengaged illustra-
tion) and then proceed with adjustment as follows.
Adjust the length of the clutch actuator link to
achieve a clutch spring assembly bolt head clear-
ance of 1/4 in. to 5/16 in. (6.35 mm to 7.94 mm) with
the clutch engaged. To adjust length: remove ball
joint from clutch arm and shorten the clutch actua-
tor link to increase this measurement, or lengthen
the clutch actuator link to decrease this measure-
ment. If adjustments are needed more frequently
than every 100 hours to maintain dimensions, it may
suggest problems with pulley wear or belt misalign-
ment.
