To question the validity of some parameters subsoilers

Abstract

This article presents questions of the fertile layer and plough-pan softening without soil overturning and stubble field damage. It is worked out an original construction and proved basics parameters of the two-stage double-row chisel plow working body, the use of which will allow to improve tillage quality, to destroy subsurface compacted layer and reduce soil cultivation power capacity. Conducted field trials allowed to quantify working bodies of chisel plow for tractors of diverse drawbar category.
