Adjustments

Step 3 -

Neutral Function Adjustment

1. Securely block the tractor up so the drive tires

are off the ground.

2. Adjust the tracking adjustment nuts at the

front of both control rods so that 2 or 3

threads are visible, then loosen the jam nuts

on the ball joints at the back of the control

rods.

WARNING

The following adjustments are made with

the engine running. Keep all body parts

and tools away from rotating and hot com-

ponents, and secure all loose clothing.

With the FSC in

NEUTRAL-PARK

, start the

engine. With the engine at normal operating

speed, check for movement of the drive

wheels.

4. Using a wrench on one tracking adjustment

nut, rotate the control rod

counterclockwise

just until the wheel on that side begins

move forward

. Then, counting the turns

required, rotate the control rod

clockwise

just

until the wheel stops and then begins

move in reverse

. Rotate the control rod back

counterclockwise half the number of turns

required to make the wheel go from moving

forward to reverse. The transmission is now

centered in the neutral window. Tighten the

jam nut on the ball joint and repeat the same

procedure on the other transmission.

5. Turn off the engine, and then lower the drive

tires onto the ground.

Step 4 -

Straight Tracking Adjustment

1. Sit in the seat, start the engine, set throttle at

full speed, and with the FSC in the

NEU-

TRAL-PARK

po sition check for movement of

either drive wheel (if either wheel moves

backward or forward, re fer to

Step 3 - Neutral

Function Adjustment on page 65

and read-

just).

2. Check for straight ground tracking on a level

surface (with hands off the steering levers).

Set the FSC at several different speeds and

ob serve if the machine moves in a straight

line (use cement joint or other line on ground

for refer ence).

If tracking is not straight, shorten the control

rod on the faster side by turning the tracking

adjustment nut clockwise. If straight tracking

and neutral are both achieved, proceed to the

next step. If straight tracking and neutral

cannot both be achieved, turn the tracking

adjustment nut on the faster side counter-

clockwise until neutral is restored.
