RECOMMENDATIONS FOR IMPROVING THE GRIPPING-AND-TRACTION PROP-
ERTIES OF THE TRACTOR AND SATISFYING THE STEERABILITY CRITERION
The tractor design provides for possible
variation of the tractor operating weight
and improvement of gripping and traction
properties by way of tire ballasting and
twinning of wheels as follows:
•
Twinning of the front and rear wheels
of the tractor.
• Filling the tyre tubes of tractor wheels
with liquid.
• Using the standard (front) ballast and
optional ballast (counterweights) to be
installed on the rear or front hitch cou-
pler.
Twinning the wheels makes it possible to
reduce substantially the specific pressure
on the ground and to preserve the soil
structure, especially that of wetted fields.
Twinning the wheels on dense soils
makes it possible to improve the gripping
and traction characteristics of the tractor,
especially in conjunction with correct
choice of the combination method: the
values of the load and ballasting should
not exceed the permissible values.
ATTENTION!
• For highly efficient employment of the
tractor on jobs of different kinds, in a
wide range of traction, it is necessary
to follow recommendations on loading
duties (see Table 7-20).
• Additional loading of the wheels by
filling liquid (solution) into the tyre
tubes of the tractor should be only
used in case of insufficient tyre grip
with the soil under adverse condi-
tions (water-logged ground, etc.). If
tyre gripping is satisfactory, filling the
tyre tubes with liquid is not recom-
mended, as it results in overload of
the transmission and working equip-
ment attached to the tractor.
• The tyres filled with liquid impair the
smoothness of tractor running at
speeds exceeding 20 km/h (transpor-
tation works).
ATTENTION! NEVER fill in the tyre
tubes to their full volume, because it
can result in the tyre carcass break in
case of running over an obstacle on
the road.
