6.1 PARKING BRAKE ADJUSTMENT

WARNING:

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 rear of the machine. Raise the machine and support it to prevent it from falling. Block the caster wheels to prevent the machine from moving. Remove the drive wheels.

2.Loosen the nut on the top of the actuator bar until it is flush with the end of the bolt. (See Figure 6-2, top view).

3.Measure the distance between frame and the top of the actuator bar. The distance should be 1-1/4". If this measurement is not at the specified 1-1/4", adjust the brake control rod. Adjust by loosening the jam nuts at both ends of the brake control rod and turning the rod until the proper distance is achieved. Tighten the jam nuts. (See Figure 6-1).

5.When the 1-1/4" measurement has been acheived, tighten the nut on the top of the actuator bar until the measurement between the frame and actuator bar is approximately 2".

6.Check the measurement on the RH side between the frame and actuator bar. This measurement should be approximately 2". If the measurement is not at 2", tighten or loosen the nut on top of the actuator bar until the 2" measurement is acheived.

7.Replace the drive wheels and test the brake.

-NOTE-

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