Twinning of the Rear Wheels
To improve the tractive and adhesive
performance of the tractor when operat-
ing it with heavy agricultural machines on
soils with low supporting capacity, addi-
tional rear wheels 18.4R38 can be in-
stalled through spacer-ring pieces.
To install the additional wheel, jack up
the rear-end of the tractor having placed
preliminarily chocks in front of and be-
hind the front wheels; remove the main
rear wheel, press the short bolts out of
the hub (2) and install the elongated
bolts (1) (complete with the spacer-ring
piece). Put the main wheel onto the
elongated bolts (1) and fasten it with
wheel nuts (3); then place the spacer-
ring piece (4) onto the same bolts and
fasten it with nuts (5). Then install the
additional wheel onto the bolts (6) of the
spacer-ring piece and fasten it with nits
(7).
Tighten the nuts (7) with applying the
torque of 200…250 N • m (20…25 kgf • m).
When performing the lobs in the interrows
with the width of 450 and 700 mm, it is rec-
ommended to install the twinned wheels
11,2R42 (see Section “Aggregation”).
