PARKING BRAKE ADJUSTMENT6.1
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.
Position a floor jack under the rear of the machine. 1.
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.
With the brake lever in the disengaged position,
2.
check the distance between the top of the frame
tube and the bottom of the brake handle. The
distance should be 2" to 2-1/4" (See Figure 6-1).
If the distance is not at the specified measurement, 3.
adjust by loosening the jam nuts at both ends of the
brake control rod and turning the rod until the proper
distance is achieved. (See Figure 6-1). Tighten the
jam nuts.
With the brake in the engaged position, check the
4.
spring compression between the two flat washers on
the LH side of the machine. The distance should be
1-7/16". (See Figure 6-2).
If the distance is not at the specified measurement,
5.
loosen the jam nut at the rod end side of the brake
actuator rod. (See Figure 6-2).
Turn the adjustment bolt (clockwise to decrease 6.
the spring compression or counter clockwise to
increase the spring compression) until the 1-7/16"
measurement is achieved and tighten the jam nut.
(See Figure 6-2).
Repeat steps 4 though 6 on the RH side of the 7.
