Blade Clutch (PTO)
Clutch Engagement/Belt Tension
The clutch engagement and PTO belt tension are
adjusted 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
actuator link to increase this measurement, or
lengthen the clutch actuator link to decrease this
measurement. If adjustments are needed more
frequently than every 100 hours to maintain dimen
sions, it may suggest problems with pulley wear or
belt misalignment.
