Tests and Adjustments
Steering Linkage Adjustments
See Figures 7-2 through 7-7.
IMPORTANT
The following adjustments must be performed in
sequence to ensure correct steering linkage
adjustment.
Tie Rod Adjustment
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Turn the wheels to the straight-ahead position.
Figure 7-2
3. Measure the distance between the center lines of the
tires at the front (1) and rear (5) of the tires. The
measurement (toe-in) at the front of the tires should
be a maximum of 0.0625 in. (1.6 mm) less than the
distance at the rear of the tires. If the toe-in does not
meet specifications, adjust as follows:
a. Loosen the tie rod clamp bolts/nuts (2 and 4) on
both sides of the tie rod (3).
b. Turn the tie rod (3) as needed to obtain proper
toe-in (1).
c. Retighten the tie rod clamp bolts/nuts (2 and 4).
d. Proceed to “Turning Radius (Equal Angle)
Adjustment.”
Turning Radius (Equal Angle) Adjustment
IMPORTANT
The steering linkage must be adjusted in proper
sequence. Do not perform this procedure until the tie
rod adjustment has been performed. (See “Tie Rod
Adjustment” on page 7-4.)
1. Check the turning radius by driving the mower in a
circle in both a hard right and a hard left turn.
2. Measure the diameters of the tire track circles. Adjust
steering cylinder rod ball joints as needed until equal
angles are achieved.
3. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
4. Turn the wheels to the straight-ahead position.
5. Check that ball joints are threaded equally into both
ends of steering cylinder.
