摘要： A base frame for a roll-over disc plow can be symmetrical about a longitudinal axis and can be adapted to be secured to a standard tractor hitch. A plow frame can overlay and be pivoted to the base frame about the longitudinal axis. The plow frame can be hydraulically moved about one hundred eighty degrees between extreme positions.

摘要： In accordance with the present invention, there is provided a tillage conservation plow (100) for plowing the earth and exposing, on the surface of the earth, weeds and past harvest residue. The plow includes a hitch frame (1) and a framework (2) connected to the hitch frame. A support (10) is connected to the framework. The support is operable to allow the earth to pass unturned. A blade (4) is connected to the moldboard support. The support, in combination with the blade, is operable to place the weeds and past harvest residue on the surface of the earth without turning over the soil.

摘要： A reversible multi-disc plow has its main frame, to which the plow beam is pivoted, connected in front by a vertical pivot to a mounting frame which made for connection to the three point lifting system of a tractor. The pivotal movement of the main frame relative to the mounting frame is resisted by a spring loaded pivot box. If, during plowing, a disc strikes an obstacle, the plow main frame will pivot against the spring-loading to reduce stress on the plow and its parts.

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： There is provided soil loosening and furrower assemblies and a bed renovator therefor. The soil loosening assembly comprises a blade assembly and wherein the blade assembly is horizontally pitched such that, when drawn beneath a soil surface at a fixed depth, the horizontally pitched blade assembly severs rootstock at the level of the blade assembly while retaining the rootstock substantially in place and loosens soil above the level of the blade assembly without substantial soil inversion. The furrower assembly comprises side plates extending rearwardly from a forward prow edge, wherein the side plates are approximately 25-45° with respect to the horizontal axis; and bottom edges of the side plates are approximately 20-40° with respect to a direction-of-travel axis.
