flat area which is free of other persons and
obstructions before and after adjustment.
Caution

Loosen the jam nut and adjust the clevis accordingly
(Fig. 43).
4.
Assemble the clevis to the brake shaft (Fig. 43).
5.
Check the amount of free travel of the brake pedal when
the adjustment is completed. There should be 1/2 to
1 in. (13 to 26 mm) travel before the brake shoes make
contact with the brake drums. Readjust, if necessary, to
achieve this setting.
6.
Transport the machine and depress the brake pedal; both
brakes should lock equally. Readjust, if necessary.
7.
It is recommended that the brakes be burnished
annually; refer to Break-In Period, page 21.
Adjusting the Rear Camshaft
A camshaft misaligned with the valve bank may cause the
following:
•
No increase in ground speed in the No. 2 (transport)
traction selection
•
The mow pedal will not stay depressed (in detent)
without foot pressure.
•
Slow lift of the cutting units
•
Slow or no drive to the cutting units
If one or more malfunctions occur, loosen the rear camshaft
mounting capscrews (Fig. 44) and relocate the cam shaft
until
the condition is corrected. Tighten the capscrews.
Important
Readjust the mow/lift switch and the lift and
mow pedal height when the camshaft adjustment is
completed.
