ADJUSTMENTS
Blade Clutch (PTO)
Clutch Engagement/Belt Tension
The clutch engagement and PTO belt tension are ad-
justed using the clutch rod. Initially, after installing
new PTO belts,
after 10 hours and every 100 hours
thereafter, check and adjust for the dimensions as
shown in the
PTO Clutch Engaged
and
PTO Clutch
Disengaged
illustrations.
Adjust the length of the clutch rod 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
rod to
decrease
this measurement or
lengthen
the
clutch rod to
increase
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.
NOTE:
Do not allow clutch arm to bottom out the
plunger on safety switch. Adjust switch down if condi-
tion exists.
