WORKING ELEMENTS WITH REPETITIVE CUTTING ANGLES FOR SUBSURFACE PLOUGHS

Abstract

Cutting angle of soil that depends on the corners of the moving soil direction along the wedge and position of a ploughshare towards the furrow bottom is theoretically defined and proved experimentally. Cutting angle of soil with a threesided wedge is the universal power characteristic when cultivating soil. On the basis of theoretical researches the deep-cutting working elements with the increasing and repetitive cutting angles on each part of a ploughshare is developed and it improves soil crumbling.
