Substantiation of installation parameters of additional soil tilling implements in plowing units due to the movement of the furrow slice on the surfaces of the plough body

The article represents the equation of furrow slice movement along the moldboard depending on the speed of the unit, it characterizes the curvature of the angle trajectory, the gravity force of the furrow slice, the applied traction force and the resistance force caused by rehandling of the furrow slice particles as it rolls up along the moldboard. Analytical expressions are obtained for determining the time of the furrow slice movement along the moldboard, the coordinates of the furrow slice fall on the field surface and the estimation of the fall time. The results can be used in the field of agricultural engineering in the design of reversible ploughs and additional implements for soil surface treatment.
