Adjust Caster Tread Width

The rear casters can be adjusted to a narrow tread width to allow loading and shipping without having to remove them.

A narrow tread width also suits smaller headers by allowing more space to the uncut crop, and provides more maneuverability around poles, irrigation inlets, or other obstacles.

A wider tread width is useful in heavy crops that produce large windrows so that run over is reduced.

Adjust the caster tread width as follows:

CAUTION: Park on a firm, flat, level surface header on the ground, the GSL in N-DETENT and steering wheel locked.

1. Park the windrower on a firm, level surface with the header on the surface, GSL in N-DETENT and steering wheel locked.

2. Stop the engine and remove the key.

3. CAUTION: The lifting device should have a lifting capacity of 2270 kg (5000 lbs).

   Raise rear of windrower slightly so that most of the weight is off the casters, using a jack or other suitable lifting device under the frame at location shown.
