6.1PARKING BRAKE ADJUSTMENT

WARNING:

Park Brake Control

Do not operate the mower if the parking brake is not operable. Possible severe injury could result.

The parking brake linkage should be adjusted whenever the parking brake lever is placed in the “ENGAGE” position and the parking brake will not prevent the mower from moving. If the following procedures do not allow you to engage the parking brake properly, contact your Scag dealer for further brake adjustments.

1.Position a floor jack under the left side of the machine behind the drive wheel. Raise the machine and support it to prevent it from falling. Block the caster wheels to prevent the machine from moving. Remove the right drive wheel and reinstall (2) lug nuts to hold the hub on.

2.With the brake lever in the engaged position, check to see if the lever plunges the brake switch within 1/ 8" of bottoming out. (See Figure 6-1). To increase the distance, loosen the jam nuts on the parking brake control rod and turn the rod clockwise. To decrease the distance, turn the rod counterclockwise. (See Figure 6-2).

3.With the brake in the engaged position, check the distance between the lower nut on the brake actuator rod and the spring housing. The distance should be approximately 1/16". (See Figure 6-3).

4.Turn the nut at the top of the brake connector link until the 1/16" measurement is achieved and tighten the jam nut at the connector link on the brake actuator rod. (See Figure 6-3).

5.Repeat steps 3 and 4 on other side. Replace the drive wheels and test the brake.

-NOTE-

If this procedure does not achieve proper brake adjustment, please contact your authorized Scag dealer.
