ABSTRACT:
A plow having a main frame beam disposed in a diagonal direction with respect to the direction of travel and having a plurality of plow bottoms equally spaced along the diagonal beam, each bottom being vertically pivotally supported on the beam. A furrow wheel frame is carried on the rear of the beam to swing about a vertical axis. The plow bottoms and wheel frame are connected together and are power operated so that the plows may have their effective plowing width adjusted while at the same time positioning the furrow wheel frame. A hitch connection is carried on the forward end of the plow and is composed of a first part which is adapted for connection to a tractor and a second part which is rearward of the first part and adapted to shift with the plow frame. The two parts are connected by a vertical pivot to permit relative lateral swinging between the parts. Master and slave cylinders extend respectively between the first and second parts of the hitch and furrow wheel frame and the furrow wheel so that upon adjusting the width of cut of the plow bottoms on the go which would tend to shift the hitch parts relative to one another the position of the rear furrow wheel with respect to the wheel frame is automatically adjusted. The master and slave cylinders are so mounted and dimensioned that the rear wheel will automatically adjust itself with respect to the direction of travel in order to achieve desired steering of the rear wheel and resultant positioning of the rear position of the frame.
