Abstract
Two cultivators, in combination, form an assembly with a first implement having fixed soil penetrating members and a second cultivator has rotatary soil working members with tines that intensely work the soil broken by the first cultivator. Each cultivator has a corresponding coupling member at the forward portion of its frame and each coupling member is connectable to the lifting hitch of a conventional tractor independently of the other implement. Alternatively, the coupling members can be interlinked to one another with pivotable arms so that each cultivator is independently movable with respect to one another for a limited extent in vertical directions. A supporting roller can be positioned to the rear of the second cultivator.
Claims13
A soil-cultivating assembly comprising a combination of two cultivating implements positioned one behind the other, each of said implements having a frame and a coupling member for independent and alternative connection to one another and to a prime mover, a first implement being positioned as a leading implement and having tines rigidly fixed to a corresponding frame and a second implement having rotatable soil-working tined members that revolve about upwardly extending axes, driving means for revolving said soil-working members and said driving means being in driving engagement with a power take-off of the prime mover, the coupling members of said two implements being interconnected with a three-point lifting device of the prime mover, the front of the frame of said leading implement having its corresponding coupling member positioned for connection to the three-point lifting device of the prime mover, arm means being provided, between the rear of said coupling member and the coupling member of the said second implement for linking said respective coupling members, said arm means comprising upper arm means and lower arm means, stop means being positioned adjacent said lower arm means to limit movements of same.
A soil cultivating assembly comprising a combination of two cultivating implements positioned one behind the other, each of said implements having a frame and a coupling member, a first implement having fixed tines on its corresponding frame and at its coupling member secured at the forward portion of that frame for direct connection to a three-point lifting device of a prime mover, the rear of that frame having means for connection to the coupling member of a second implement, the coupling members of said implements being linked to one another by an upper arm means and a lower arm means, said lower arm means extending beneath the frame of said first implement and stop means being positioned adjacent said lower arm means to limit the movements of same, said second implement having rotatable soil working members and driving means connected to said members.
