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. 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.
2. With the brake in the engaged position, check the
distance between the notch on the brake actuator
rod and pivot bushing on the LH side of the machine.
The distance should be 1/8". See Figure 6-1.
3. If the distance is not at the specified measurement,
turn the adjustment nut on the brake actuator rod
until the 1/8" measurement is achieved. See Figure
6-1.
4. Repeat steps 2-3 on the RH side of the machine.
5. Test the brake.
- NOTE -
If this procedure does not achieve proper brake
adjustment, please contact your authorized Scag
dealer.
