Adjusting 4x4 Front Tread with Reversible Rims

4 x 4 front axle tread with reversible rims can be adjusted repositioning or changing the rims or inverting wheel disks.

The tread can also be adjusted switching the whole wheel to opposite side of tractor. (This maneuver allows a concave to convex wheel position change without having to disassemble them).

When changing rear wheels from one side to other of front axle with front-wheel drive, the arrow on side of tire must be pointing in direction of forward travel.

The relation between wheel disk and rim, according to required treads, is illustrated on the following page.

Carefully study diagrams before changing tread as this will reduce effort when performing this task.

IMPORTANT: After adjusting space between front wheels, tighten nuts between disk and rim and between disk and hub. Drive tractor about 100 meters (398 ft 96 in.) and retighten to specification.
