Wheels, Tyres and Treads

Tread Settings—Multi-Position Rear Wheels
Wheel tread on rear axle with multi-position wheels
can be adjusted by repositioning or exchanging the
rims or by reversing the wheel disks.
Wheel tread can also be adjusted by exchanging the
complete wheel to the opposite side of the tractor (This
maneuver permits the change from disk-dished-in to
disk-dished-out operations without disassembling the
wheel). When changing rear wheels from one side to
the other, the arrow on side wall of tyre points in the
direction of forward rotation.
The relationship of the wheel disk and rim in obtaining
the different tread settings is shown in the diagrams on
the facing page.
A study of these diagrams, before attempting to
change tread settings, will save unnecessary labor.
IMPORTANT: After setting wheel spacing, tighten
rim-to-disk and disk-to-flange bolts.
Drive tractor 100 m (109 yd) and
tighten again.
