or if the mower belt is slipping.
CLUTCH ROD ADJUSTMENT -
38” (97 CM) & 44”(112 CM) MODELS
NOTE: When adjusting 44” (112 cm) mowers, perform
the idler pulley adjustment found on the next page
FIRST. Clutch rod adjustment should only be performed
after the idler pulley has been adjusted.
1. Disengage the PTO lever. Set the mower height
adjustment lever to mid-cut position.
2. Loosen the set collar (B, Figure 32a).
3. Pull the clutch rod back until the cotter pin and wash-
er (C) contacts the U-shaped bracket (D). Slide the
set collar (B) forward to remove all slack from the
clutch rod and spring assembly. The collar should be
touching the spring, but not compressing it.
4. Tighten the set collar (B). Note: the set screw should
face the rear of the unit.
5. Engage the PTO lever.
6. Measure the length of the compressed clutch spring
(A). The spring should be 2-7/8” to 3” (7.3 cm to 7.62
cm) when compressed.
7. Check the mower blade stopping time. The blades
should stop within 5 seconds. If the blades do not
stop within 5 seconds contact your authorized dealer.
