Parking Brake Adjustments. Scag Power Equipment STHM, STHM Three-Wheel Rider

ADJUSTMENTS

PARKING BRAKE

Minor brake adjustments can be made by loosening the top nut on both brake cables (see Figure 4).

Back the nuts off approximately 1/4". While pulling one cable downward, tighten the bottom nut on the cable until it touches the bottom of the brake cable mount. Tighten both the top and bottom nuts to lock the cable in place. Repeat the above steps for the second brake cable. Make sure that both cables are adjusted evenly so that the brakes do not cause the mower to pull to the left or right.

-NOTE-

This is a minor brake adjustment. If the brakes do not function properly after this adjustment, see your Scag Service Dealer before operating your mower.

If the drive wheels consistently rotate when foot pedal control is in neutral, go to step 4.

If the drive wheels inconsistently rotate, i.e. drive wheels sometimes rotate and sometimes do not when foot pedal is not depressed, then check neutral adjustment bolt for "zero free play" in neutral control spring.

-NOTE-

If there is free play in the foot pedal have your

SCAG servicing dealer inspect the machine and repair it as needed.

4. If the drive wheels rotate in the forward travel direction, turn the adjustment bolt clockwise until the tire rotation stops. If the drive wheels rotate in the backward travel direction, turn the adjustment bolt counter-clockwise until the tire rotation stops (See

Figure 5).
