Maintenance Instructions
REPLACING/REPAIRING
Blade Clutch (PTO)
Clutch Engagement/Belt Tension
The clutch engagement and PTO belt tension are
adjusted using the clutch actuator rod. Initially, after
installing a new PTO belt,
after 10 hours and every
100 hours
thereafter, check and adjust for the two
dimensions in the clutch actuator rod as shown in
the
PTO Clutch Engaged
and
PTO Clutch Disen-
gaged
illustrations.
Adjust the bolt head clearance [1/4 to 3/8 in.
(6.35 to 9.53 mm)] first (clutch engaged), then adjust
uncompressed spring length (clutch disengaged).
The spring must be adjusted to an uncompressed
overall length of 2-1/8 in. (54 mm). If adjustments
are needed more frequently than every 100 hours to
maintain the linkage dimensions, it may suggest
problems with pulley wear or belt misalignment.
