Abstract: An agricultural implement combination has a forward cultivator with soil working blades that rotate about a horizontal axis extending transverse to the direction of travel and a rear harrow having tined soil working members that rotate about upwardly extending shafts positioned in a row also extending transverse to the direction of travel. The cultivator and harrow each have a coupling member and their coupling members are linked by pairs of arms that cross one another when the implement is viewed from the side. A driving system includes a separate transmisson with change speed gearing for the cultivator and the harrow and the input shaft of the cultivator is connectable to a prime mover p.t.o. A telescope shaft connection bridges the two transmissions so that the blades of the cultivator and the tined members of the harrow can be driven from a single p.t.o. The harrow preferably has a supporting roller at the rear to smooth the soil worked first by the cultivator and then by the harrow.

Abstract: An implement attachment in the form of, for example, a backhoe is mounted on the three-point hitch of a tractor having an internal hydraulic system which is incapable of preventing free upward swinging on the part of the hitch links. The implement itself includes a main frame attached to the hitch and a digging tool swingably mounted on the frame such that substantial resistance to digging by the tool generates a force which tends to lift the frame and the hitch links from the ground.

Abstract: A rotary harrow attachment has a frame portion to which coupling elements can be connected in alternative locations so that the attachment can be connected to the front or the rear of a prime mover on a multi-point hitch. The p.t.o. of the prime mover is drivenly connectable to the soil working members by a gear box which is also detachable and repositionable 180.degree. on the frame portion.

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.
