ADJUSTMENTS/ MAINTENANCE
PARK LOCK BRAKE ADJUSTMENT (CONTINUED)
The Park-Lock Brake must be adjusted to hold the Control Lever
at the rear of the “PARK/START” slot in the console. Otherwise,
while starting the engine, the Hydrostatic Control Lever will need
to be held back to fully depress the safety switch located under
the console cover.
The Park-Lock Brake is adjusted by tightening or loosening nut
"A”, Figure 19.
FRONT WHEEL TOE-IN ADJUSTMENT - FIGURE 22
Proper toe-in of the front wheels is necessary to assure proper
steering and to reduce tire wear. The proper amount of toe-in is
when the front of the wheels are 1/16” to 1/8” closer together
than the rear of the wheels, measured at the horizontal centerline
of the rim flange.
If the steering developes a wandering characteristic or if ex­
cessive 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 22.
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 ob­
tained.
BRAKE ADJUSTMENT - FIGURE 21
The tractor brakes will require adjustment when the Brake Pedal
depresses over two inches. To adjust the brakes proceed as
follows:
1. Jack up the rear of the tractor so that the wheels can be
rotated by hand to feel the brake drag. (Do not run
engine.) Open free-wheeling valves according to instruc­
tions on page 7.
2. Tighten the two hex nuts on one disc brake pad assembly
to adjust the brakes. See Figure 21. Adjust the two nuts
evenly, while rocking the wheel back and forth gently until
the brakes just start to drag. From that point, back each
nut off 1/8 turn.
3. Adjust brake on opposite wheel in the same fashion.
STEERING GEAR ADJUSTMENT
If excessive looseness is noticed in the steering system afte
continued use, the steering gear may require adjusting to
remove excessive backlash between the gears. Adjust steering
gear using the following procedure:
1. Raise front of tractor so that the tires clear the ground and
are in the straight forward position.
2. Remove cotter pin identified in Figure 22.
3. Loosen Jam Nut ”C”, Figure 22, and turn adjusting
screw out (counter-clockwise 1-1/2 turns.)
4. Tighten adjusting plug, Figure 22, to 4-6 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.
6. Hold jam nut and turn adjusting screw. Figure 22 “IN”
(clockwise) until backlash is removed from steering
wheel. This procedure must be done at the position where
wheels are straight forward. DO NOT FORCE ADJUSTING
SCREW. Torque jam nuts 35-45 ft. lbs. while holding ad­
justing screw in position.
7. Turn steering wheel from lock to lock and check for
binding or dragging inside gearbox. If any binding or drag^
ging exists, it will be necessary to loosen the adjustini
screw and/or the adjusting plug slightly until steering
wheel turns freely with no excessive looseness.
FIGURE 22
STEERING STOP ADJUSTMENT - FIGURE 23
When making a full right hand turn, the spindle arm should coggi*
tact the axle stop as shown in Figure 23. When making a full lev,
hand turn, the left spindle arm should contact the left axle stop.
See your Ariens dealer for adjustment if steering wheel reaches
full travel in either direction before the spindle arm contacts the
axle stop.
