Abstract
A reel for a harvesting machine includes a plurality of circumferentially spaced radially extending support arms, a plurality of axially extending bat tubes rotatably supported on the outer end portions of the support arms, a plurality of axially spaced tines, preferably made from a synthetic thermoplastic or thermosetting material, mounted on each bat tube and a spring having one end connected to each bat tube and a support carried by the reel. The spring holds the bat tube in an operating position where the tines are at a predetermined angular orientation relative to the rotational axis of the reel during normal operation. If one or more tines on one bat tube engages a plug of wet hay or other obstruction, the spring permits the bat tube to rotate in a direction opposite to the rotational direction of the reel to a deflected position where the tine(s) can ride over the obstruction.
