WARNING
To avoid serious injury, perform mainten¬
ance on the tractor or mower only when the
engine is stopped. Always remove ignition
key before beginning the maintenance to
prevent accidental starting of the engine.
Drive Belt Stop Adjustment
If the main drive belt does not stop when the
clutch-brake pedal is depressed, the belt stops may
need adjustment (see figure 34). The belt stops
should be adjusted so there is a 1/16 (1.5 mm) gap
between the belt stop and the belt when the belt is
tight (clutch engaged). To adjust a belt stop, loosen
the bolt that secures it and move the belt stop
slightly before retightening the bolt. Then recheck
the adjustment. Bolt should be torqued to 25
ft./lbs.
36 INCH MOWER ADJUSTMENTS
The following adjustments are for the 36 inch
mower. Proper mower adjustment is necessary for
efficient and safe mower operation.
Drive Belt Tension Adjustment
If the mower slips or fails to drive, the mower belt
tension may need adjustment. To check for proper
adjustment, lower the mower, place the PTO lever
in the engaged position. Then measure the gap be¬
tween the rod guide (item A, figure 35) and the set
collar (item B). The gap should be 3/8T/2 inch (10
-13 mm). If it is not, perform adjustment as follows:
1.
Place the PTO lever in the disengaged posi¬
tion.
2.
Loosen the setscrew (item C) in the set collar
(item B).
3.
Move the set collar on the PTO rod slightly for¬
ward to increase the gap, slightly rearward to
decrease the gap.
4.
Retighten setscrew (item C).
5.
Repeat the measurement of the gap and the ad¬
justment until the gap measures 3/8-1/2 inch
(10-13 mm).
