Blade Clutch (PTO)
Clutch Engagement/Belt Tension
The clutch engagement and PTO belt tension are ad-
justed using the clutch actuator rod. Initially, after in-
stalling a new PTO belt, after 10 hours and every
100 hours thereafter, check and adjust for the two di-
mensions 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 in. to 3/8 in.
(6.35 mm to 9.53 mm)] first (clutch engaged), then
adjust uncompressed spring length (clutch dis-
engaged). The spring must be adjusted to an un-
compressed overall length of 2 in. (51 mm). If ad-
justments are needed more frequently than every
100 hours to maintain the linkage dimensions, it may
suggest problems with pulley wear or belt misalign-
ment.
