Kistechok O. Substantiations of the circuit and parameters of the arable unit with forward and back hinged ploughs

In basis of dissertational work the hypothesis is fixed that the increase of coupling weight of tractor due to use of a frontal plough at approximately identical traction - power parameters may provide increase width of capture of the arable unit under the circuit "push - pull" at least for width of one case in comparison with МТU with only one back hinge the instrument. The increase of coupling weight of a tractor, in turn, should to result in reduction of slipping wheels and specific expenses of fuel. The scientific hypothesis is confirmed with results theoretical and experimental researches traction - power, coursing (in horizontal and longitudinal-vertical planes) and exploitation - technological parameters arable МТU on the basis of tractor KHТZ -160.
