Front

oe-In
Service Interval/Specification
Maintaining correct front wheel toe–in is important
for safety, Smart Turn Steering operation and ease
of use. If uneven tire wear, lawn scuffing or hard
steering develop, adjustment may be required. Check
the toe-in after every 100 operating hours or once a
year, whichever occurs first (Fig. 41).
Maintain the following specification: 1/8–1/4 inch
(3.5–6.5 mm) toe-in on the front wheels.
Measuring Toe-In
1. Disengage the power take off (PTO), set the
parking brake, lower the attachment lift, and turn
the ignition key to “STOP” to stop the engine.
Remove the ignition key.
2. Turn the wheels straight ahead.
3. Push the front of the tires out to remove normal
looseness in the linkage.
4. Measure the distance between both of the front
tires at spindle level (at the front and rear of the
wheels) (Fig. 41).
5. The front measurement should be 1/8” to 1/4” (3
to 6 mm) less than the rear measurement. If
adjustment is needed, follow the instructions in
Adjusting Toe–In, page 39.

Adjusting Toe-In
1. Loosen the jam nuts at the ends of the steering
rods (Fig. 42).
2. Rotate both steering rods equal amounts to
adjust the toe–in to 1/8” to 1/4” (3 to 6 mm).
3. Hold each tie rod end with one wrench and
tighten the jam nut with a second wrench.
IMPORTANT: Make sure that the flat surface
on the top of the front tie rod ends is parallel
to the bottom of the steering arm (Fig. 43).
