Theoretical Study of the Trajectory of Movement of a Ploughing Aggregate with a Reversible Plough on the Headlands

Ploughing with reversible ploughs is increasingly used. Their main advantage is that the aggregates based on them allow ploughing without formation of dump ridges and breakup furrows (i.e. ensure formation of a smooth field surface). The trajectory of the movement of the ploughing aggregate with a reversible plough on the headlands has its own specifics and length due to the fact that the aggregate moves across the field in a shuttle way (i.e., processing is constantly carried out at the butt in relation to the previous pass). This trajectory depends on the length of the cultivated field and the working width of the plough. In comparison with the conventional aggregates the total length of the path of movement of the ploughing aggregates with reversible ploughs on the headland under certain conditions may be much larger. As estimated indicators in the work there are taken the total lengths of the trajectories of movement of the ploughing aggregates with reversible and conventional ploughs on the headland. On the basis of theoretical studies comparative calculated graphic dependences of the length of the trajectory of the movement of the ploughing aggregates were constructed for various lengths of the track (length of the cultivated field) and various plough widths. It will be an obvious advantage of the ploughing aggregate as part of a wheeled tractor with a minimum turning radius of not more than 5.3 m with a field length of 1400 m.
