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
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 dimensions, it may suggest
problems with pulley wear or belt misalignment.
