Abstract

1444074 Haymaker R WEIDTMANN 6 Feb 1974 [23 Feb 1973 27 June 1973 24 July 1973] 05503/74 Heading A1F A plurality of tines 2 are each pivotally mounted upon respective base plates 8 integral with a ring 1, the ring constituting part of a rotor for a haymaking machine. The mounting of each tine comprises two mutually perpendicular axes 33 and 16, the former passing through a pair of helical springs 31 which hold the tine in its operating position whilst enabling it to deflect rearward (relative to the direction of rotation) on striking an obstruction, and the latter passing through a hinge about which the tine rotates by means of centrifugal force derived from the spinning rotor, from its inoperative position 2" to its operating position 2 against the action of a spring 24. Each tine can also be adjusted by rotation about a bolt 6 from a tedding position 2 to a windrowing position 2' and held in the required position by means of a spring biased plunger 12 engaging holes in base plate 8. In addition, pivotally mounted upon the rotor away from its axis are windrowing attachments or guides (not shown) which may be adjusted in conjunction with the tines.
