<p>A reversible multi-disk plow of the type having a main frame connected, at its front, to the three point lifting system of a tractor. A beam is pivoted to the main frame about a verticalaxis for swinging movement to right and left hand ploughing positions. A rear or furrow wheel are provided at the rear of the beam, and a number of hangers for plow disks are pivoted about vertical axes to the beam. The hangers are mounted for simultaneously pivoting automatically, relative to the beam, when the beam is swung to either of its said positions. A pivot connectis the main frame to the mounting means for pivotal movement of the main frame about a substantially vertical axis relative to the mounting means, and spring-loading means resist this pivotal movement.</p> |
