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 in. to 3/8 in.
(6.35 mm to 9.53 mm)] first (clutch engaged), then
adjust uncompressed spring length (clutch disen-
gaged). The spring must be adjusted to an uncom-
pressed 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 misalign-
ment.
