ADJUSTMENTS
Blade Clutch (PTO)
Clutch Engagement/Belt Tension
The clutch engagement and PTO belt tension are
adjusted using the clutch link. Initially, after install-
ing new PTO belts,
after 10 hours and every 100
hours
thereafter, check and adjust for the dimen-
sions as shown in the
PTO Clutch Engaged
and
PTO Clutch Disengaged
illustrations.
Adjust the length of the clutch link to achieve a 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,
shorten
the clutch
link to
increase
this measurement or
lengthen
the
clutch 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.
