<p>A pull type swather is provided with an adjustable hitch assembly for converting the swather as between a field position in which it is pulled widthwise by a tractor and a transport position in which it is pulled substantially lengthwise. The hitch assembly comprises a hitch pole pivotally connected to the swather frame and the hitch pole and a hydraulic cylinder for extending and retracting the telescopic assembly so as to change the angle of the hitch pole as between the field and transport positions. The swather also includes pivotal wheel assemblies movable by separate hydraulic cylinders as between field and transport wheel positions. The respective hydraulic cylinders are connected in series in a hydraulic circuit for least-resistance sequence operation when converting the apparatus as between the field and transport configurations. The apparatus allows for effortless conversion as between the field and transport configurations.</p> |
