COMPARATIVE ANALYSIS OF THE IDLE MOVE LENGTH WHEN MAKING T-TURNS BY A MOUNTED MACHINE TRACTOR UNIT IN A FIELD OF IRREGULAR SHAPE

The productivity of machine-tractor units depends on the length idle move performed in headland. Analytical dependences for determining when making T-turns by a unit with mounted machine field irregular shape have been specified article. Five types considered two variants – open turn and closed turn. Each them is carried out directions motion. A total 20 turns described. methodology specific consisting tractor row seeder has demonstrated. It established that had smallest direction from right to left. For three studied turns, same travelling Right-to-left shown provide headland, which compared other turns.
