Filed: 1975-09-15
Abstract: 1506219 Hay-making machines MASCHINENFABRIK FAHR AG 15 Sept 1975 [18 Sept 1974] 37801/75 Heading A1F A hay-making machine for tedding and swathing has one or more rake heads wherein tine arms 13 mounted in a rotating ring 10 may swivel about their longitudinal axes and, in bearings 15, about axes tangential to the ring; the inner ends of the tine arms being supported in a revolving bearing 22 on a cam disc 21 which is itself secured against rotation but is axially displaceable by turning a threaded spindle 11 to adjust the altitude of the tine arms. In the raised position of the cam disc, control levers 20, on the tine arms, co-operate with the cam disc to swivel the tine arms about their longitudinal axes. The cam disc is mounted on a universal joint 23 so that in its extreme positions it may have an inclination imposed upon it by stops or abutments. Further, the path of the bearings 22 may not be planar. When tedding the tine arms are held in their raised position by detent means such that they cannot pivot about their longitudinal axes, and the axis of the spindle 11 is inclined in the direction of travel.
