Brake
Before each use, check brakes for proper operation.
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 key.
2. Rear wheels must lock when you try to push the
machine forward. Adjustment is required if the
wheels turn and do not lock; refer to Adjusting
the Brake, page 28.
3. Release the brake and press upper control bar
very lightly, approximately 1/2 in. (13 mm),
wheels should rotate freely.
4. If both conditions are met no adjustment is
required.
Adjusting the Brake
The brake lever is on the upper control bar (Fig. 10).
If the parking brake does not hold securely or the
control bar is not parallel with the fixed bar, an
adjustment is required.
1. Check the brake before you adjust it; refer to
Checking the Brake, page 28.
2. Release the parking brake; refer to Releasing the
Parking Brake, page 16.
3. To adjust the brake remove the cotter pin and
washer from the brake lever (Fig. 28).
4. Rotate the wing nut so the trunnion 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 28.
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.
