A hay making machine including a carrying structure which can be attached to a tractor such that the carrying structure can travel with the tractor in a forward direction. A substantially vertical support axle is mounted to the carrying structure and supports a rotor having hay making tools. A girder is attached to the support axle. A support structure is articulated to the girder via one substantially vertical pivot spindle positioned forward of the support axle. Two beams, each carrying two carrying wheels, are connected to the support at opposite sides. At curves and turns of the trajectory of the tractor, all of the carrying wheels will pivot together with their beams and the support structure around the pivot spindle. The wheels will therefore be oriented together, without skidding, in the forward direction.
