    摘要： A main frame is secured to a tractor for towing wherein the main frame is tilted as the tractor tilts to one side or the other of the path of travel A ball and socket joint suspends the tool bar by its central portion from the main frame so that the tool bar can swing from a position angling forwardly and to one side to a second position angling forwardly and to the other side The moldboards being fixed to an suspended below the tool bar cause the tool bar to rotate about its longitudinal axis automatically swing by gravity to upright positions for plowing, regardless of the tilt of the main frame. A latch plate latches the tool bar in its rotated position on the frame The tool moldboards have clamps which are adjustable along the length of the tool bar for adapting the plow to wide wheel or narrow wheel base tractors.

    摘要： A plough having a landslide and tilling mechanism, illustrated as a rotary disc or soil inversion wheel, which is pivotable in relation to the landslide between alternative positions providing for the left-hand or right-hand formation of a furrow, depending upon the direction of ploughing, when the plough is required to operate back and forth across a field.

    摘要： A fully mounted variable width plow of the roll-over type or not in which the tractor hitch links are pivoted about generally vertical axes permitting the hitch limited movement in a horizontal plane, which will allow the adjusted plow to maintain correct alignment under the action of the soil. The plow system includes a plow beam, to the forward end of which a forecarriage is pivotally attached about a vertical axis, and a plurality of interconnected plow bottom assemblies. Actuation of a hydraulic cylinder will result in equal pivotal movement of each plow bottom assembly relative to the plow beam as well as pivotal movement between the forecarriage and the plow beam.

    摘要： A semi-mounted roll over plow which includes an auxiliary frame rotatably mounted on a main frame with pairs of plow bottoms mounted on opposite sides of the auxiliary frame. The auxiliary frame includes forward and rear branches extending angularly with respect to the main frame in parallel but offset relationship to each other. A ground engaging wheel is mounted at approximately the center of the plow and can be actuated to both raise and lower the main frame to provide clearance to roll the auxiliary frame about the main frame and pivoted in response to turning movement of the semi-mounting hitch to cause the wheel to pivot so that the plow tracks a tractor to which it is attached during turns.
