ADJUSTMENTS
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 allow the mower to
move. If the following procedures do not allow you to
engage the parking brake properly, contact your Scag
dealer for further brake adjustments.
1. Adjust the parking brake so that tension is felt
approximately 1" before the brake hand lever is
against the stop on the handle bar.
2. Adjust the brake actuator rod on either side of the
machine to obtain proper brake adjustment.
-NOTE-
If this procedure does not achieve proper brake
adjustment, please contact your authorized Scag
dealer.
6.2 TRAVEL ADJUSTMENTS
Neutral or tracking adjustments will need to be made if:
A. The steering control is in the neutral position and
the machine creeps forward or backward.
(Neutral Adjustment).
B. The steering control is in the full forward position
and the mower pulls to one side or the other
when traveling in a forward direction. (Tracking
Adjustment, See Page 23).
Neutral Adjustment
1. Be sure the dump valves are in the run position and
the speed control lever is in the neutral lock position.
2. On a flat level surface, start the engine and disengage
the parking brake.
3. Run the engine at full operating speed and check if
the machine creeps forward or backwards.
CAUTION:
Adjust the brake only enough to hold the ma-
chine. Excessive force may cause damage to the
machine or brake components.
