ADJUSTMENTS

6.1 parking brake adjustment

1.Adjust the parking brake so that when the brake hand lever is against the stop on the handle bar, the brake levers on the brake shaft weldment are against the stops on the engine deck.

Caution

Adjust the brake only enough to hold the machine. Excessive force may cause damage to the machine or brake components.

2.Adjust the brake actuator rod on either side of the machine to obtain proper brake adjustment.

6.2 Neutral adjustment

-NOTE-

Neutral has been set by your Scag dealer at the time of set up and normally does not need to be adjusted. If, however, you find that the neutral has come out of adjustment, follow the procedure below.

1.Raise the drive wheels off the ground and block the caster wheels to prevent the machine from moving.

2.Make sure the speed control lever is in neutral, the steering control levers are in the neutral latch position, and the parking brake is on. Start the engine.

3.Release the parking brake and note if the tires are rotating.

4.Start on the left side of the machine, using the adjustment wrench located on the left side of the machine. Rotate the tracking adjustment nut counter clockwise just until the LH wheel starts to creep forward. Make note of the position of the adjustment nut. Repeat on the right side as needed. See Figure 6-1.

5.Turn the adjustment nut clockwise just until the wheel turns rearward. Make note of the position of the adjustment nut. To adjust neutral, split the difference between the two noted positions of the adjustment nut. Repeat on the right side as needed.

6.Place the wrench in the holder on the left side of the machine and turn the engine off.

ADJUSTMENTS

-NOTE-

This adjustment is made to allow the steering control levers to be moved out of the neutral latch without engaging reverse

Before making this adjustment be sure that the speed control bearing is just touching the speed control cam and that the bellcrank bearing is resting in the center groove of the neutral cam.

1.Remove the speed control spring. Remove the steering control rod swivel hair pin. Check the location of the swivel in the slotted hole in the bellcrank.

2.Turn the swivel joint on the steering control rods until the swivel joint is centered in the slot in the bellcrank..
