tf the steering develops a wandering characteristic or if
excessive tire wear develops, the toe-in of the front wheels
should be checked. If the toe-in is incorrect, adjust as follows:
1. Loosen jam nuts A and B,' Figure 23.
2. Rotate tie-rod until toe-in is correct. Shorten tie-rod to
decrease toe-in. Lengthen it to increase toe-in.
3. Tighten jam nuts A and B after correct toe-in is obtained.
BRAKE ADJUSTMENT
The tractor brakes will require adjustment when the brake
pedal depresses over two inches. To adjust the brakes proceed
as follows:
1. Block up the rear of the tractor with the wheels off the
ground.
2. Remove the wheel lug nuts and remove the wheel.
3. Insert a screw driver in the slot in the brake drum (See
Figure 22) and tighten the star washer until the brakes are
snug and the drum does not turn. Back off the star washer
one full turn.
4. Replace the wheel and secure with the wheel lug nuts.
Repeat adjustment on the opposite wheel.

STEERING GEAR adjustment
If excessive looseness is noticed in the steering system after
continued use, the steering gear may require adjusting to re­
move excessive backlash between the gears. Adjust steering
gear using the following procedure:
1. Raise front of tractor so that the tires clear the ground.
2. Remove cotter pm identified in Figure 23.
3. Loosen jam nut C, Figure 23 and turn adjusting screw out
(counter-clockwise)
1 V 2 turns.
4. Tighten adjusting plug. Figure 23, to 10-14 ft. lbs. of
torque.
5. Rotate adjusting plug out slightly to align nearest slot in
the plug with the cotter pin hole and reinstall the cotter pin.

. Hold jam nut and turn adjusting screw. Figure23,
clockwise (in) until backlash is removed from steering wheel.
DO NOT FORCE ADJUSTING SCREW. Torque jam nuts
35-45 ft. lbs. while holding adjusting screw in position.
k 7. Turn steering wheel from lock to lock and check for
^binding or dragging inside gearbox. If any binding or
dragging exists, it will be necessary to loosen the adjusting

STEERING STOP ADJUSTMENT
When making a full right hand turn, the spindle arm
should contact the axle stop as shown in Figure 24. When
making a full left hand turn, the left spindle arm should
contact the left axle stop. Proceed as follows to adjust the
steering stops after checking toe-in.
1. Rotate front wheels to the right until right spindle arm
contacts the axle stop. Figure 24.
2. Remove drag link rod end from steering arm. Figure 24,
and loosen jam nuts A.
2a. Rotate steering wheel clockwise until steering gear bottoms.
Back off 1/8-1/4 turn counter clockwise.
3. Rotate drag link as required while preventing the loose rod
end from turning until the stud is approximately Vs hole to
the rear of hole in steering arm. Figure24. Be sure axle stop
contacts steering arm.
4. Reinstall rod end stud in steering arm and tighten jam
nuts A.
5. Rotate wheels completely to the left. The left spindle
arm should contact left axle stop. If it does not, repeat step
2 and shorten drag links slightly until both spindle arms con­
tact their respective axle stops when making full turns in
either direction. The steering gear should not bottom before
the spindle arm contacts the axle stop.
