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, first reset them to their factory preset lengths (as
shown in the PTO Clutch Disengaged illustration)
and then proceed with adjustment as follows.
Adjust the length of the clutch actuator link to achieve
a clutch spring assembly bolt head clearance 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 in-
crease this measurement, or lengthen the clutch ac-
tuator link to decrease this measurement. If adjust-
ments are needed more frequently than every 100
hours to maintain dimensions, it may suggest prob-
lems with pulley wear or belt misalignment.
