Soil cultivating implement combinations
First Claim
1. A soil cultivating implement combination comprising a forward cultivator having a main frame beam with downwardly extending tines secured to said beam, said beam extending transverse to the normal direction of travel of said combination, rotary ground support means connected to the lateral ends of said beam, said support means including an adjustment device to vertically regulate the working depths of said tines, a harrow linked to said cultivator at the rear thereof, said harrow comprising a frame and a plurality of soil working members rotatably mounted on said frame, driving means connected to said soil working members and a rear ground supporting roller connected to said frame by adjustable arm means, whereby the working depths of said soil working members can be controlled, said frame beam and frame being linked to one another by a linkage for relative independent vertical movements, said driving means including a driving shaft that extends forwardly through said cultivator for connection to a p.t.o. of a prime mover and said cultivator having coupling means for connection to a lifting hitch of the prime mover.

Abstract
A combination implement has a leading cultivator with fixed tines and a rear rotary harrow with driven soil working tined members. The cultivator has side ground wheels with vertical adjusting means that controls the working depths of the fixed tines. The harrow has a trailing roller that is interconnected to the harrow frame with arms that also have an adjustment feature so that the working depths of the harrow'"'"'s tined members can be regulated. The cultivator and harrow are linked to one another by a parallelogram linkage so that they can be disconnected from one another and individually connected to the three point lift of a prime mover. When the combination is assembled, a suspended drive shaft of the harrow'"'"'s driving system is passed through the cultivator and connected to the p.t.o. of the prime mover.

- 2. A soil cultivating implement combination comprising a cultivator with frame beam means and downwardly extending tines fixed to said beam means, said combination comprising a rotary harrow having a plurality of tined soil working members rotatably supported on a frame of said harrow, said soil working members being rotatable about corresponding upwardly extending shafts and driving means drivenly connected to said shafts, said beam means having at least one ground supporting member that regulates the working depths of the tines and the frame of said harrow being connected to a further ground supporting member that controls the working depths of said tined members and both said cultivator and said rotary harrow having corresponding coupling means that can be individually coupled to the three-point lifting device of a tractor.
