Energy efficiency of rotary brush cutters

Abstract

The paper is devoted to emergent issues of reduction of power consumption and increase of efficiency of machinery and equipment used to remove shrub weeds and trees as well as recycle cutting residues left in the course of clearing the area intended for future buildings, clearings, roadside zones. The paper deals with methods to determine the cutting resistance forces for typical cutting parts of rotary brush cutters widely used around the world. The paper also presents the results of experimental research of the functioning of some cutting parts and the analysis of their efficiency.
