Abstract: A positionable work implement with an increased working width. The positionable work implement includes a main frame, and wheel assemblies and implement assemblies mounted on the main frame. The main frame is pivotable about a vertical axis, pivoting between several working positions and a travelling position wherein the effective transverse width of the frame in the travelling position is reduced relative to the effective transverse width of the frame in the various working positions. The implement assemblies may include rotary basket hay rakes with a center idler wheel to increase the effective working width of the hay rake. Also, the rotary basket hay rakes may be mounted in tandem, working together, to increase the effective working width of the raking mechanism. Finally, a self-propelled version of the positionable work implement is contemplated.

Abstract: A harrow assembly adapted to be towed by a towing vehicle in either a working mode or a transport mode. The harrow assembly includes front and rear offset disc harrow units pivoted at one end portion. Each offset disc harrow unit includes a transport wheel assembly, each assembly having a pair of opposed, spaced transport wheels arranged on either side of the respective harrow units.

Abstract: Forward and rear gang disc harrow carriers are hingedly joined near corresponding ends by a vertical axis hinge structure. Near their other corresponding ends, the gang disc harrow carriers are interconnected through a four element linkage having an operating cylinder and a latch bar whereby the carriers can be positioned at varying prescribed angles for working the soil and in parallel locked relationship for transport. Transport wheels are pivotally attached to the rear carrier and are equipped with power cylinders which raise and lower the wheels for lowering and raising the rear carrier. The front carrier has a pivotal connection with a drawbar and another power cylinder is connected between the drawbar and front carrier and is operable to raise and lower the front carrier.
