A soil cultivating machine has a beamed frame, and working members arranged in pairs. Two working members are mounted one behind the other, preferably on a common carrier beam which is releasably secured to transverse beams of the frame. Thus the two working members and the carrier beam constitute a working unit which is readily releasable from the frame. The two working members of the pair are interlinked by a connecting rod to ensure a uniform operating depth over irregular ground and the members can be located on opposite sides of the carrier beam as viewed in plan. In one embodiment, the working members are mounted on pivot pins journalled to different frame beams and the members are arranged in rows that are inclined to the direction of travel. The beams with working members can be arranged in groups that are hinged to one another for elevation to a reduced transport position. A wheeled central frame portion has an intermediate frame portion and an outer frame portion to each side which are linked to a respective swingable arm. The arm can be turned by a hydraulic ram so that, first, the outer portion is raised and then the intermediate portion is elevated above the central portion.
A soil cultivating machine comprising a frame and at least two soil working members being mounted on a common beam of said frame, one behind the other with respect to the normal direction of machine travel and on opposite sides of said beam, said two members being linked to one another and detachably fastened with said beam as a unit to the remainder of the frame, said common beam extending in the direction of travel and bridging two transverse frame beams, said common beam being a channel beam with sides and said members being located adjacent a respective beam side, each working member comprising a supporting arm and said arm having an upper end pivotally connected to said common beam, said upper end being fastened to stub shaft means that comprises a stub shaft journalled to the sides of said common beam.
A soil cultivating machine comprising a beamed frame and a plurality of cultivating tools being mounted on said frame, said tools being mounted in pairs one behind the other with respect to the direction of machine travel, each of said tools including an upwardly extending carrier and the respective carriers of the tools in each pair being pivoted to one another by a tie rod, each carrier being pivoted to the frame with a pivot pin that extends transverse to the direction of travel and said pin mounting a crank arm, said tie rod interconnecting the crank arms of the tools of each pair, said tools being arranged in at least three rows wherein a foremost tool is connected to a hindmost tool and an adjacent central tool is connected to either a foremost or a hindmost tool.
