HYDROSTATIC CONTROL ADJUSTMENT
The hydrostatic transmission control is in correct ad¬
justment when the tractor does not move with the
engine running, the clutch engaged and the hydrostatic
control lever in the neutral position.
If adjustment is necessary, follow these steps:
1. Raise both rear wheels off the ground by placing
blocks under the rear frame.
2. Loosen the lock nut (left hand thread) on the end
of the control rod. See figure 14.
3. Place the hydrostatic control lever in the neutral
position.
4. Start the tractor.
5. Release the clutch-brake pedal.
NOTE: DO NOT set the parking brake or the relief valve.
A
WARNING: Be careful of the cooling fan on
the hydrostatic transmission.
6. Turn the control rod back and forth until the rear
wheels do not rotate.
7. Shut off the engine.
8. Tighten the lock nut on the control rod.
9. Remove the blocks under the tractor frame and
test the tractor operation.
LEVELING THE DECK
1. Check tire pressure in ail four tires. Recommended
pressure is approximately 12 p.s.i.
2. Make certain all deck wheels are mounted in same
relative location.
3. On a level surface, engage the PTO and lower the
deck until it reaches the ground.
All four deck wheels should reach the ground at
the same time. If they do not, adjust the deck links
as necessary.
NOTE: When adjusting the deck links, disengage the
PTO. Remove the hairpin clip and washer from the weld
bolt. Thread eyebolt up or down the link as necessary,
and reassemble.
4. Raise the deck V
2
" to T above the aground.
Check to be certain the distance from the bottom
edge of the deck to the ground is the same on both
sides of the deck. If it is not, adjust the links on
the left side of the unit.
Check to be certain the front of the deck is 1/4"
to 3/8" lower than the rear of the deck. If it is not,
adjust the two front links to obtain this distance.
STEERING WHEEL ADJUSTMENT
There are four height positions for the steering wheel.
To adjust the height of the steering wheel, remove the
hex bolt and hex lock nut on the steering shaft. Place
the steering wheel in the position desired and secure
with hex bolt and hex lock nut. Refer to figure 4.
NOTE: When raising the height of the steering wheel,
stretch the steering bellow to cover the steering shaft.
The steering shaft may also be adjusted if there is too
much play between the steering gear and segment. To
adjust, loosen the hex bolt and nut on the front of the
bearing retainer bracket. See figure 15. Pry the bear¬
ing retainer bracket toward the right until the steering
gear engages solidly into the teeth of the steering seg¬
ment. Retighten the hex bolt and nut.
BRAKE ADJUSTMENT (See figure 15)
The brake is located by the right rear wheel inside the
frame. During normal operation of this machine, the
brakes are subject to wear and will require periodic ex¬
amination and adjustment.
WARNING: Do not adjust the brake while
the engine Is running. Be sure to block the
wheels of the tractor before making the
brake adjustment.
To adjust the brake, remove the cotter pin. Adjust the
castle nut so the brake starts to engage when the brake
lever is 1/4" to 5/16" away from the axle housing.
NOTE: Figure 16 is shown with the unit tipped up on
rear wheels for clarity only.
