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.

6.3 STEERING CONTROL ROD
ADJUSTMENTS
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.
3. Reinstall the speed control spring onto the swivel.
Install the hair pin onto the swivel. See Figure 6-2.
