agricultural engineering. SUBSTANCE: moldboard plow has moldboard bodies and furrow ripper made in the form of tine with hoe. Hoe point is positioned forward of moldboard of front body and is offset relative to body share toward soil layer pushing away side for distance equal to 0.4-0.9 of rear body width. Nonsymmetrical hoe has chisel of width exceeding that of hoe tine. Hoe wing is directed toward plow moldboard bodies. Plow of such construction provides effective thinning of subsurface layer, since furrow bottom is ripped upon passage of tractor wheels through furrow, with tractor wheels moving on solid plow bottom. EFFECT: increased efficiency, minimum manufacture and operating costs, reduced power consumption and enhanced reliability in operation. 4 dwg
