Abstrakt
The gap between two technological operations should be minimal in the production
environment. For this, special combined (multi-operational) machine-and-tractor units (MTU)
are used. Their agricultural machines have sequentially installed working devices for various
technological purposes. In the absence of such MTUs, single-operation units are used. Such units
more often have different working widths. For their simultaneous operation in the same field, the
first unit (for example, a sowing unit) must have a wider width than the second one (for example,
a rolling one). In practice, the opposite case occurs more often when the first unit's working width
is less than the second unit's working width. As a result, the first machine-and-tractor unit delays
the work of the second one. This article aims to develop the algorithm for the simultaneous
operation of two machine-and-tractor units of different field performance. The first of them
(a sowing unit) has a working width of 3.6 m, and the second (a rolling one) is 6.1 m. As a result,
the following has been established using the example of processing a field of 80 hectares: the
second unit should start its work (i.e., rolling the crops) when the first one (sowing) has sown a
certain area. According to the formula proposed in the article, the size of this area is 44 hectares.
Under natural working conditions, the second unit (rolling) started its work after the first (sowing)
unit has sown 44 hectares of the field area. As a result, both units have completed the entire area
with a half-hour gap, i.e., practically simultaneously and without delay from each other.
