Neutral Adjustment; Steering Control Rod Adjustment; Tracking Adjustment - Scag Power Equipment SWZ Serie Manual Del Operador

NEUTRAL ADJUSTMENT

-NOTE-
Neutral has been set by your Scag dealer at the
time of setup 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. Starting 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 a note of the position of the adjust-
ment nut. (See Figure 12)
5. Turn the adjustment nut clockwise just until the wheel
turns rearward. Make a 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.

STEERING CONTROL ROD
ADJUSTMENT
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 bell
crank.
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 13).

TRACKING ADJUSTMENT

that the tire pressures are correct, (see page 8)
and that the neutral adjustment and the steering
control rod adjustment have been completed.

engine and place the speed adjustment lever into the
speed that will most often be used.
