The front wheels of the tractor are mounted on flanges of FDA wheel reduction
units.
Rear wheels of the tractor are mounted on hubs, which consist of split tapered in-
serts 3 and 4 (figure 3.13.1) and a hub body 2.
The inserts are tightened in the hub body with eight bolts 1 (M20) with a torque of
550 to 600 N·m and thus they clench the axle shaft.

Tire operating rules, selection of best internal pressure in tires depending on work-
ing conditions and tractor axes loading and also methods of track adjustment and of wheel
