FRONT WHEEL TOE-IN
Front wheel toe-in adjustments on your tractor
were made at the factory. Normally, the wheels
maintain their toe-in ; however, an occasional
check should be made.
Checking Toe-In
1. With the front wheels in the straight-ahead posi-
tion, mark the front of the wheels (not the tires)
at wheel hub height, Figure
77 .
2. Measure and record the distance between the
front of the wheels at the marks, then push the
tractor forward or backward until marks are at
wheel hub height on the rear of the wheel.
3. Measure and record the distance between the
marks at the rear of the wheels.
4. The difference between the dimensions re-
corded in Step 2 and 3 should give zero to 0-5
mm toe-in. The distance between the marks on
the wheels should be zero to 0-5 mm greater
when the marks are at the rear than at the front.
5. If the toe-in is not correct, adjust as outlined in
the following procedure.
Figure 77 - Checking Toe-In
Adjusting Toe-In
1. Loosen the tie rod lock nuts.
2. Adjust the tie rod tube assembly as required to
give zero to 0-5 mm toe-in.
3. After the correct toe-in is obtained, tighten the
tie rod lock nuts.
FOOT- BRAKE ADJUSTMENT
Whenever the brake pedal travel becomes exces-
sive, or if the travel of one pedal is unequal to that
of the other, adjustment of each pedal should be
made in the following manner :
Figure 78 - Brake Pedal Adjustment
1. Loosen the lock-nut, Figure
78 , and rotate the
brake rod as necessary until there is 20-30mm
of pedal free play. Lengthening the rod in-
creases free play while shortening the rod de-
creases free play.
2. Test drive the tractor to make sure the braking
action of both rear wheels is equal. Readjust as
necessary.
