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 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.
