Features of the wear of the working bodies of the Viking tillage unit

It is shown that the most uniform wear of the bit blade occurs when soil particles move perpendicular to the blade edge. It has been determined that the width of the edge affects the traction resistance of the body, the penetration ability, and the strength of the blade. It has been found that in case of loamy soils, the optimal width of the blade part is in the range between 70 and 80 mm at an acute angle of 50 degrees between the bit blade and the side edge.
