a long straight stick is enough in the field environment. If the blades of the ploughshare are
situated at different height, and the plough bodies are in different planes, then the plough
shall move unsteady, the drawbar resistance and the fuel consumption will increase.
3.10 Operating at reverse motion
A number of works (feedworks, sugar-beat harvesting, etc.) requires driving of the agricul-
tural unit across a harvested field. In this case technological process fulfillment at reverse
motion justifies extra costs. In this case mounted and semi-mounted implements are used
(mini-harvesters, harvesters, etc.). A trailer for receiving grinded stuff which is connected
to a tractor via front towing device (also if front weights are installed) or via cross-bar at a
suspension axle of the front hitch linkage HL-2 can be attached to make a harvesting ag-
gregate unit. Reset to a reverse gear and than to forward gear again takes 3...5 min.

Driving on the roads of general purpose is performed only at forward motion. The motion
on reverse is not permitted as signaling and lighting equipment is designed only for for-
ward motion.
3.11 Choosing travel speed
The speed of motion of the tractors on public roads can be limited by the technical pos-
sibilities of the tractor and aggregated machine in accordance with the sign provided on
the technical mean, characteristics of the machines (method of aggregation, overall di-
mensions, operating weight and absence of the braking system) as well as motion condi-
tions.
