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 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. With the brake lever in the disengaged position, 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).

3. If the distance is not at the specified measurement,

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.

4. With the brake in the engaged position, check the

distance between the lower nut on the brake actuator

rod and the brake actuator lever on the LH side of the

machine.  The distance should be 1/8" (See Figure 6-

2).

5. If the distance is not at the specified measurement,

loosen the jam nut at the clevis on the top of the

brake actuator rod (See Figure 6-2).

6. Turn the bolt at the bottom of the brake actuator lever

until the 1/8" measurement is achieved and tighten the

jam nut at the clevis on the brake actuator rod. (See

Figure 6-2).

7. Repeat steps 4-6 on the RH side of the machine.

8. Replace the drive wheels and test the brake.

-NOTE-

If this proceedure 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 levers are in the neutral

position and the machine creeps forward or

backward. (Neutral Adjustment, See Page 19).
