    摘要： A reversible disk plow having a main frame and a tool-carrying subframe mounted intermediate its ends on a rear end portion of the main frame for lateral swinging movement about a vertical axis between alternate right- and left-hand plowing positions. An offset rear furrow wheel is carried by a mounting frame which is mounted on the rear end of a subframe for lateral swinging movement about a vertical axis between alternate right- and lefthand plowing positions. Linkage means are provided for swinging the mounting frame between its alternate plowing positions and to reverse the furrow wheel as the subframe is swung between its alternate plowing positions.

    摘要： A semimounted rollover two-way plow having right- and left-hand plow bottoms rotatably mounted about a generally longitudinally extending tubular member, the tubular member being supported at its rear end by a steerable rear furrow wheel and at its front end by a transversely shiftable hitch crossbar. A pair of singleacting hydraulic cylinders rotate the plow bottoms between their alternate plowing positions while a first double-acting hydraulic cylinder sets the rear furrow wheel at alternate angular positions for right- and left-hand plowing so that the rear furrow wheel will be laterally offset from the centerline of the tractor and a second double-acting hydraulic cylinder sets the crossbar at alternate lateral positions for right- and left-hand plowing. The double-acting hydraulic cylinders are connected in parallel with each other and each of the single-acting cylinders is connected in parallel with one end of each of the doubleacting cylinders so that when the plow bottoms are rotated between their alternate positions, the rear furrow wheel and hitch crossbar are simultaneously moved to their respective alternate positions.
