Adjustments; Tractor Brake - Simplicity LTH Series Operator's Manual

Adjustments
WARNING
To avoid serious injury, perform adjustment only with
engine stopped, key removed, and tractor on level
ground.
WARNING
Disconnect the battery cables, negative cable first
before performing adjustments. If this is not done, the
electrical circuit can easily be shorted to the frame by a
tool, which could cause sparks or electrical shock.
TRACTOR BRAKE ADJUSTMENT
1. With clutch/brake pedal released, rotate the brake cam
(A, figure 30) forward until it stops. There should be
3/16" gap between transaxle housing (B) and rear point
of brake cam.
2. If adjustment is required, remove cotter pin and turn
adjusting nut (C) until proper 3/16" clearance is
achieved. Turning the nut in will decrease clearance and
turning the nut out will increase clearance. Reinstall
cotter pin after adjustment.
3. Depress the clutch/brake pedal and latch parking brake
over footrest. When compressed, the brake spring (A,
figure 31) should be 3-3/8", measured between the rod
guide (B) and adjusting nut (C).
