FIGURE 18.
If frequent additions are required, locate the leak and
correct. Inadequate supply of fluid may result in per¬
manent internal damage.
If the natural color of the transmission fluid has
changed, black or milky, overheating and/or water con¬
taminate is indicated. The fluid should be drained and
replaced with new transmission fluid.
To drain the hydrostatic transmission, remove the hex
plug on the bottom of the hydrostatic transmission.
HYDROSTATIC TRANSMISSION COOLING
The hydrostatic transmission is cooled by the oil, fan
and fins. If the hydrostatic transmission runs hot, check
to see if the fan is in operating condition, the oil level
is correct and the fins are clean.
NOTE: DO NOT use high pressure water spray or steam
to clean the hydrostatic transmission.
MAINTENANCE
WARNING: Disconnect the spark plug wire
and ground against the engine before per¬
forming any adjustments, repairs or
maintenance.
TROUBLE SHOOTING
Refer to the chart on pages 19 and 20 for trouble
shooting engine problems.
CRANKCASE OIL
Check the oil level in the crankcase before each use
of the machine and after every two hours of operation.
Oil level should be maintained as instructed in the
separate engine manual.
After the first two hours of operating a new engine, drain
the oil from the crankcase while engine is still hot and
refill crankcase with new oil; thereafter change the oil
after every 25 hours of operation. Refer to the engine
manual.
FUEL FILTER
Your unit is equipped with a replaceable in-line fuel
filter. Replace filter whenever contamination or
discoloration is noticed. Order replacement filter
through your authorized engine service dealer.
WHEEL ADJUSTMENT
The caster (forward slant of the king pin) and the
camber (tilt of the wheels out at the top) require no ad¬
justment. Automotive steering principles have been
used to determine the caster and camber on the trac¬
tor. The front wheels should toe-in 1/8 inch.
To adjust the toe-in, follow thesa stops.
1. Remove the hex nut and lock washer, and drop
the end of the tie rod from the axle bracket. See
figure 19.
2. Loosen the hex jam nut on tie rod.
3. Adjust the tie rod assembly for correct toe-in.
Dimension "B" should be approximately 1/8" less than
Dimension "A." See figure 20. To increase Dimension
"B," screw tie rod into tie rod end. To decrease Dimen¬
sion "B," unscrew tie rod from tie rod end. Reassem¬
ble tie rod. Check dimensions. Readjust if necessary.

DRAG LINK
If the drag link or ball joints are changed, the new
assembly must be adjusted to the exact same length
as the original. If adjusted incorrectly, it will allow the
tractor to turn sharper one direction than the other.
To take off the drag link, remove the nuts and lock
washers holding the ball joint to the steering gear and
right front axle bracket See figure 19.
ENGINE
Refer to separate engine manual for alt engine main¬
tenance procedures.
