A pull-type crop engaging machine such as a rotary mower comprises a frame mounted on transversely spaced field ground wheels for movement with a hitch arm extending to a tractor and a transport assembly attached behind the frame for moving downwardly to a transport position so that in the transport position the hitch arm extends from one end of the frame generally in the transverse direction for towing the machine in the transverse direction. The transport includes a transport ground wheel which acts to raise the frame to pass underneath the crop engaging system to support the machine on the wheel, on a second wheel behind the frame and on the hitch. The movement of the hitch and the wheel is connected and started at a position of the hitch so that the machine remains balanced. A shield behind the frame includes a portion which moves with the transport wheel.

A pull-type rotary mower comprises a frame with a transverse main beam mounted on transversely spaced field ground wheels for movement with a central hitch arm extending to a tractor and a transport assembly attached to the main beam the frame for moving downwardly to a transport position so that in the transport position the hitch arm extends from one end of the frame generally in the transverse direction for towing the machine in the transverse direction. The transport includes front and rear transport ground wheel which act to support the machine on the wheels. A shield assembly, which in the field position extends rearwardly behind the frame to engage the crop emerging from a conditioner within a center discharge opening, includes at least a portion which is moved to a retracted position at the frame to allow the rear transport wheel to move to the transport position.

A crop header has generally horizontal flail disks mounted for driven rotation about generally upright axes. A pair of conditioner rolls is mounted in a discharge opening. A crop converging system includes two over-shot auger elements defined by a common auger shaft with an auger flight carried thereon arranged generally longitudinal of the cutter bar so as to carry the cut crop longitudinally of the cutter bar to the entrance opening. Each auger element is arranged with a forwardmost tangent to the auger flight located behind the axes of the rotary disks and with an outer end thereof spaced outwardly of the respective end of the entrance mouth. The common auger shaft is driven by a common rotary drive with the bottom roll of the conditioner rolls. The augers terminate inwardly of the outer end of the cutter bar to locate the drive inboard of the end plates.

A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. The driven wheels are driven by hydraulic motors each having their own drive pump the output of which is controlled by a cam plate. There is provided an automatic steering system having a guidance controller arranged to receive GPS position information and feed back signals and to generate output for controlling a hydraulic control valve for controlling flow in hydraulic fluid for a double acting hydraulic control cylinder arranged to actuate pivotal movement of the steering link member independently of the steering shaft.

A pull-type crop harvesting machine has a header carried on a frame mounted on ground wheels with a hitch arm extending from the frame over the header to a hitch coupling of a tractor. The hitch arm is mounted for pivotal movement about a generally upright axis such that in a first position the tractor tows the frame in echelon to one side and in a second position the tractor tows the frame in echelon. The movement is actuated by a hydraulic cylinder and stopped at one end of the movement by the piston with a rod coupling being adjustably mounted on the rod to adjust the end position. At the other end of the movement, the position is defined by a stop member mounted on the piston rod and adjustable relative thereto. Each end of the cylinder includes a cushion effect by using separate orifices for the fluid ports which slow fluid flow as the piston approaches the ends of the cylinder.
