Abstract
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.
Claims21
A roll-over disc plow, the plow comprising:
- a base frame comprising a leading beam and at least one side beam;
- a plow frame comprising a plow beam and a cross beam;
- and
- a plurality of plow discs coupled with the plow beam,
- wherein the leading beam of the base frame is rotationally coupled with the cross beam of the plow frame, the at least one side beam of the base frame is rotationally coupled with the plow beam of the plow frame, and the cross beam is configured such that an adjustable gap exists between a rearward surface of the cross beam and the at least one side beam, and when the plow is under load the cross beam can rest upon the at least one side beam and flex rearwardly, the cross beam being further configured such that a close abutting relationship between the rearward surface of the cross beam and the at least one side beam occurs when the plow is subject to a predetermined plowing load.
A roll-over disc plow comprising a base frame symmetrical in plan about a longitudinal axis and including a transverse leading beam and side beams merging with the ends of said leading beam and having a convergence rearwardly, a coaxial forward journal in said leading beam, a coaxial rearward journal in said convergence, a plow frame including a plow beam extending diagonally in plan across said axis and including a cross beam adapted to flex rearwardly under load, means for mounting said plow frame in said forward journal and in said rearward journal, a plurality of plow discs arranged along and mounted on said plow beam, means interconnecting said plow frame and said base frame for rotating said plow frame about said axis and with respect to said base frame to lie in either of two extreme positions, and the cross beam and the side beams are configured such that when the plow is under load the cross beam can rest upon the side beam and flex rearwardly without laterally abutting the side beam.
