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. The latter can be set by adjusting the roller's connection to the harrow, to work deeper than the layer of soil worked by the cultivator.
