ADJUSTING REAR WHEEL TREAD WIDTH
When operating the tractor in the field, it is sometimes necessary to change the rear wheel tread width to a narrower position to avoid plant rows, or to widen the tread to improve stability when operating on slopes. The rear wheel tread width can be adjusted to any of 6 different positions ranging from 45.6 to 57.8 inches by removing the lug nuts and mounting bolts; then changing the position of the wheel disc in relationship to the rim mounting brackets and/or the rear axle. See Figure 48 and Figure 49.

IMPORTANT: The front wheel tread width cannot be adjusted. Attempting to do so will cause damage to the tractor. If removed, torque front wheel lug nuts to 57.2 - 66.5 ft. lbs.
To Adjust
WARNING: Never operate the tractor with loose wheel assembly fasteners. Always tighten the fasteners to the specified torque, and frequently check that they are tight.
IMPORTANT: When changing the tread width of the rear wheels, you must pay attention to the direction of the tire’s tread design and make certain to maintain that direction. To do this, it will at times be necessary to switch wheel assemblies from one side of the tractor to the other.
