Abstract: An agricultural plow implement includes a number of upright supports, with each support supporting a shallow tillage V-shaped sweep blade. A mounting plate is attached to the rear of each upright support and a specially adapted ripper shank, with an attached deep penetrating ripper blade, is attachable to each plate via a pair of bolts which extend through respective mounting bores in the plate. One of the bolts in each pair is a pivot bolt which provides a pivot point about which the ripper shank can swing. The other bolt is a shear pin which is designed to shear off should the ripper blade encounter an obstruction which might otherwise bend or break the ripper blade and/or the ripper shank. The ripper shank is adjustable vertically relative to the sweep blade and the ripper shank can also be pivoted 180 degrees between operative and non-operative positions when it is desired to do a sweep operation without soil ripping.
