A reel (12) for a harvesting machine (10) including a plurality of circumferentially spaced, radially extending support arms (24), a plurality of axially extending bat tubes (30) rotatably supported on the outer end portions of the support arms (24), a plurality of axially spaced tines (36), preferably made of a synthetic thermoplastic or thermosetting material, mounted on each bat tube (30) and a spring (66) having one end connected to each bat tube (30) and a support carried by the reel (12). The spring (66) holds the bat tube (30) in an operating position where the tines (36) are at a predetermined angular orientation relative to the rotational axis of the reel (12) during normal operation. If one or more tines (36) on one bat tube (30) engage a plug of wet hay or other obstruction, the spring (66) permits the bat tube (30) 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.
