Brake and Wheel Drive Linkage Adjustment

1.Check for correct brake adjustment:

Place the drive levers in the “park brake” position. The mower should not move forward or backward. If it does, tighten the wingnuts.

Place the drive levers in the “neutral lock” position. The mower should move forward and backward freely. If it does not, brake adjustment is necessary

2.Adjust brakes by adjusting wingnut on the upper end of each brake rod. Tighten the wingnut until the brakes engage when the drive levers are squeezed enough to allow the neutral lock/park brake latches to be placed into the “park brake” position.

See Figure 6 for Standard Pistol Grip handles and Figure 7 for ECS handles.

Note: The neutral lock/park brake latches must be able to be moved into the park brake position, if not, the brake linkages must be adjusted again.

3.Check for correct wheel drive linkage adjustment.

•For Pistol Grip Handles

Allow drive levers to drop into the full forward position: The clevis pin should rest in the neutral lock latch with approximately 3/16 inch to 1/4 inch (4.7–6.4 mm) clearance from the bottom of the slot (see Figure 19). Adjust if necessary.
