Abstract
A cultivating implement has rotatable soil working members that are driven about upwardly extending axes to work overlapping paths of soil. The cultivating members have downwardly extending tines. Neighboring members cooperate and are driven to turn in relative opposite directions. At the rear of the cultivating members, a beam with soil distributing members is positioned near the ground level to receive soil from cooperating members and distribute same laterally. The beam and distributing members can pivot against spring opposition to deflect rearward and avoid an obstacle.
Claims9
A soil cultivating implement comprising a frame and a plurality of rotatable soil working members arranged in a transverse row, said members being journalled in an elongated portion of said frame and said portion extending transverse to the direction of travel, said soil working members being mounted on corresponding upwardly extending shafts and having downwardly extending soil working tools, driving means connected to rotate said members about axes defined by said shafts, said members being arranged in neighboring pairs that rotate in relative opposite directions and towards one another to pass soil rearwardly between the pairs, a supporting soil crumbler roller being positioned to the rear of said row of the working members and being adjustably interconnected to the frame with means that sets the working depth of said members, an elongated substantially horizontal soil deflector beam being positioned between the row of soil working members and said roller, said beam substantially coextending with said row and being located adjacent the rear of said soil working members, near the ground to deflect and level at least part of the soil thrown rearwardly by said soil working members, setting means interconnecting said beam to the frame and the position of said beam being settable in any one of a plurality of different levels relative to the working depth of said members, said beam being normally positioned closely adjacent the ground, substantially below said frame leaving an open space between the beam and said frame, whereby a portion of the soil worked by said members can pass over the beam into the path of said roller to prepare a seed bed.
