Brake
Always set the parking brake when you stop the
machine or leave it unattended. If the parking brake
does not hold securely, an adjustment is required.
Checking the Brake
1. Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
and turn the ignition key to “OFF” to stop the
engine. Remove the ignition key.
2. Rear wheels must lock and skid when you try to
push the tractor forward. Adjustment is required
if the wheels turn and do not lock; refer to
Adjusting the Brake, page 27.
3. Release the brake and move the drive control rod
to the “PUSH” position; refer to Pushing the
Machine by Hand, page 19. Wheels should
rotate freely.
4. If both conditions are met no adjustment is
required.
IMPORTANT: Drive control rod moves to the
“OPERATE” position when the brake is
applied.
Adjusting the Brake
The brake lever is on top of the transaxle (Fig. 28). If
the parking brake does not hold securely, an
adjustment is required.
1. Check the brake before you adjust it; refer to
Checking the Brake, page 27.
2. Release the parking brake; refer to Releasing the
Parking Brake, page 10.
3. To adjust the brake remove the cotter pin and
washer from the brake lever (Fig. 28).
4. Rotate the trunnion so it smoothly slides into
brake lever (Fig. 28).
5. Secure trunnion to brake lever with washer and
cotter pin (Fig. 28).
6. Check the brake operation again; refer to
Checking the Brake, page 27.
IMPORTANT: With the parking brake
released, the rear wheels must rotate freely
when you push the mower. If brake action
and free wheel rotation cannot be achieved
contact your service dealer immediately.
