ABSTRACT:
A hay-making machine operable to move along a straight line path and a curved path includes a central support along with elongated transverse supports pivotably connected to the central support and extending from opposite sides of the central support in a direction generally perpendicular to the straight line path. Raking devices and ground-support wheels are provided on each of the transverse supports. A drawbar structure is connected to the central support and extends generally forwardly of the central support, the drawbar structure being connectable to a tractor vehicle while an undercarriage is connected to the central support and extends generally rearwardly of the central support. Running wheels are rotatably mounted on the undercarriage, and a pivotal arrangement pivotably supports the running wheel for pivotable movement about generally vertical axes. A steering device is operably connected between the pivotal arrangement and a drawbar structure for pivoting and steering the running wheels in response to alignment changes between the hay-making machine and the tractor vehicle connected to the drawbar structure.
