STUDIES REGARDING THE WORKING PROCESS EXECUTED ON PLOUGHSHARE OF PLANTING MACHINES

The planting machines are agricultural machines destined for rhizome, bulbs, tree seedling, and seedling planting on terrains more or less processed. One of the working organs most used on these machines is represented by the ploughshares. In this article we analyze the interaction between the ploughshares and soil to determine the forces that act on it according to the type (shoe, anchor, etc.) and according to soil.
