WHEEL ALIGNMENT

The front wheels should toe-in approximately 1/8 to

1/4 inch, as measured across dimensions A and B

shown in Figure 13.

Figure 13

FRONT WHEEL ADJUSTMENT

WARNING

Place the tractor on a firm and level surface.

To adjust the toe-in, proceed as follows:

1. Check the lower steering arm to ensure it is

perpendicular to the tractor frame (See Figure 13).

2. Place a mark at the same spot on both front

wheels; preferably the inner bead flange of the

wheel rims.

3. Rotate the wheels to position the marks at the front

horizontal diameter of the wheels, then measure

the distance between the marks and the bottom

edges of the tractor frame channels (See

measurement D in Figure 13). These two

measurements should be equal.

4. While holding the steering arms to prevent the

steering knuckles from moving, rotate the marks to

the rear horizontal diameter. Measure the distance

between the marks and the frame (See

measurement C in Figure 13). Measurement D

should be approximately 1/16 to 1/8 inch less than

measurement C on each side of the tractor.

5. Disconnect the front ball joints from the steering

arms by removing the hex lock nuts (Refer to

Figure 14). Manually move each wheel to achieve

the required toe-in and equal D measurements.

6. Loosen the jam nuts from the ball joints (See

Figure 14).

Figure 14

7. Making sure not to move the lower steering arm or

either wheel, turn the ball joint in or out on each tie

rod as necessary to align with the hole in each

steering arm.

8. Reinstall the ball joints in the steering arms and

secure with the hex lock nuts. Tighten the jam nuts

against the ball joints.

PIVOT BAR ADJUSTMENT

CAUTION

The tractor should be checked every 50 hours

of operation for play between the frame axle

channel and the pivot axle.

Check and adjust the pivot axle as follows:

1. Raise the front ot the tractor and set it on jack

stands, so the front wheels are suspended above

the ground.

CAUTION

For safety, block the rear wheels to prevent the

tractor from rolling and tipping or sliding the jack

stands.
