Abstract

Abstract An implement has a frame including beams assembled end to end in the shape of a W with deep tillage members depending from each beam. A towing hitch is connected to the middle of the assembly so that during operation, the beams are inclined with respect to the towing direction and the tillage members can plow deep. An elongated crumbler roller supports the rear of the frame and front ground wheels adjacent the frame sides support the front of the implement.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 193 words
A soil cultivating implement connectable to a multiple point lifting hitch of a tractor, comprising a frame having elongated frame beams assembled end to end at junctures that define a substantially W-shape, when viewed in plan, the assembly including outermost beams and interior beams that extend generally horizontal and transverse to the direction of travel and each beam extending at an oblique angle to the direction of travel, said beam mounting two spaced apart deep tillage members that depend therefrom and said tillage members being fixed to said beam intermediate the ends thereof, a multiple point coupling hitch having laterally extending arms with coupling points and said hitch being fastened to substantially the mid-point of the assembly by plate means and support means, said plate means and support means extending upwardly and forwardly from connections on said interior beams to further connections on said arms, said further connections being spaced from said coupling points, said hitch being located adjacent a vertical plane that extends transverse to the direction of machine travel and said plane containing the foremost tips of alternate junctions of the beams, said outermost beams being positioned laterally of said hitch.
Claim 2
Dependent Claim 193 words
A soil cultivating implement connectable to a multiple point lifting hitch of a tractor, comprising a frame having elongated frame beams assembled end to end at junctures that define a substantially W-shape, when viewed in plan, the assembly including outermost beams and interior beams that extend generally horizontal and transverse to the direction of travel and each beam extending at an oblique angle to the direction of travel, said beam mounting two spaced apart deep tillage members that depend therefrom and said tillage members being fixed to said beam intermediate the ends thereof, a multiple point coupling hitch having laterally extending arms with coupling points and said hitch being fastened to substantially the mid-point of the assembly by plate means and support means, said plate means and support means extending upwardly and forwardly from connections on said interior beams to further connections on said arms, said further connections being spaced from said coupling points, said hitch being located adjacent a vertical plane that extends transverse to the direction of machine travel and said plane containing the foremost tips of alternate junctions of the beams, said outermost beams being positioned laterally of said hitch.
Claim 3
Dependent Claim 35 words
A soil cultivating implement as claimed in claim 1, wherein the base of the W-shaped beam assembly is the front of the frame with respect to the normal direction of operative travel of the implement.
Claim 4
Dependent Claim 27 words
A soil cultivating implement as claimed in claim 1, wherein said beams each extend at an angle to the direction of travel and said angle exceeds 45°.
Claim 5
Dependent Claim 19 words
A soil cultivating implement as claimed in claim 1, wherein said tillage members each comprise drainage channel digging means.
Claim 6
Dependent Claim 36 words
A soil cultivating inplement as claimed in claim 1, wherein a supporting roller is connected to the assembly by arms and means on said arms adjusting the relative vertical position of said roller to said assembly.
Claim 7
Dependent Claim 57 words
A soil cultivating implement as claimed in claim 5, wherein supporting ground wheels are connected at the sides of said beam assembly and in front of said tillage members, said wheels being located near the vertical plane that extends transverse to the direction of travel and contains the foremost tips of the alternate junctions of said beams.
Claim 8
Dependent Claim 63 words
A soil cultivating implement as claimed in claim 6, wherein said wheels are connected to said assembly by adjustable arms and vertically movable about pivots relative to said frame, a respective adjustable arm being pivoted to each side of the assembly, the pivotal axis for the adjustable arm of each ground wheel coinciding with the pivot axis of the arm supporting said roller.
