The caster (forward slant of the king pin) and the
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.
Dimension "B" should be approximately 1/16-5/16" less
than Dimension "A." See Figure 26. Adjust the tie rod
assembly for correct toe-in.
Some units have adjustable tie rods so the toe-in can
be adjusted. To adjust the toe-in on these units, follow
these steps.
• Remove hairpin clip and washer, and drop the end
of the tie rod from the axle bracket. See Figure 25.
• Loosen the hex jam nut on tie rod.
• To increase Dimension "B," screw the tie rod into
the tie rod end. To decrease Dimension "B,"
unscrew the tie rod from the tie rod end.
• Reassemble tie rod. Check dimensions. Readjust if
necessary.

If any adjustments are made to the engine while the engine is running (e.g.
carburetor), disengage all clutches and blades.
