Abstract
A ripper plough for soil tillage includes a body having an upper mounting attachment end, a lower soil engaging end, a leading edge, a trailing edge, and opposed sides. A ploughshare support extends outwardly from the body from the leading edge toward the trailing edge at a plough angle of between 40 degrees and 55 degrees and extends outwardly and downwardly relative to the body at a thrust angle of between 40 degrees and 50 degrees. Ploughshares are mounted on the ploughshare support. The ploughshares have a length between a leading edge and a trailing edge of at least 1.5 feet and are spaced apart at the trailing edge by at least two feet, to provide an average lift angle of upward lift of between 10 degrees and 15 degrees.
