WHEEL ADJUSTMENT
(Units with Adjustable Tie Rod)
CARBURETOR ADJUSTMENTS
The caster (forward slant of the king pin) and the A_.
camber (tilt of the wheels out at the top) require no &
adjustment. Automotive steering principles have
been used to determine the caster and camber on
the tractor. The front wheels should toe-in between
1/16 - 5/16 inch.
To adjust the toe-in, follow these steps.
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 1/16 - 5/16"
less than Dimension "A." See Figure 20. To
increase Dimension "B," screw tie rod into tie rod
end. To decrease Dimension "B," unscrew tie rod
from tie rod end. Reassemble tie rod. Check
dimensions. Readjust if necessary.
WARNING: If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), disengage all
clutches and blades. Keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustments may be required to
compensate for differences in fuel, temperature,
altitude and load. Refer to separate engine manual
for carburetor adjustment information.
NOTE: A dirty air cleaner will cause an engine to
run rough. Be certain air cleaner is clean and
attached to the carburetor before adjusting
carburetor.
