4. Loosen the setscrew in the set collar (B). Move the rod
forward to increase gap, or backward to decrease gap.
Retighten the setscrew.

Repeat the adjustment as necessary until the distance
measures one inch with the PTO lever in engaged
position.
6. Check the adjustments of the PTO pulley belt stop and
the mower belt stops.
A WARNING
After adjusting mower belt tension, make sure all belt
adjustments and blade brake adjustment are performed.
Engage and disengage the PTO several times (with
mower attached) at full engine speed. Mower belt and
pulleys must stop in less than five (5) seconds. Refer to
Blade Brake Adjustment, page 44.
PTO Pulley Belt Stops Adjustment
There are two belt stops at the PTO pulley; one on the left
(D, figure 32) and one on the right (A, figure 33). With the
PTO lever engaged, measure the distance between the belt
stop and belt. There should be 1/16 inch {1.5 mm) clearance
between each belt stop and the belt. To adjust a belt stop,
loosen its mounting capscrew, move the belt stop, and
retighten the capscrew. Recheck the measurement. 43
