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