Wing Leveling
Before checking wing level, check that the center section
is level left to right (“Rear Eyebolt Adjustment”). Rear
eyebolts above the rear casters can affect left-right level
if out of adjustment.
Wing level is controlled entirely by gauge wheel height. If
wings are not running level, adjust gauge wheels.
Rear Eyebolt Adjustment
Side to side level at rear is controlled by eyebolts at the
lift cylinder bases. On 2-point, rear height is set by
spacers (page 26).

4.5 in. (11.4 cm)

To adjust the eyebolt, loosen the hose guide nut , then
the jam nut . Rotate the adjust nut to set bolt reveal.
Check that the hose loop is on top.
