A harvester reel having a shaft is journalled on a supporting frame of a harvesting vehicle for rotation relative to the frame about a main horizontal, transverse axis. A pair of mounting arms are axially spaced apart on and fixed to the shaft, which may be tubular. Extending parallel to the axis and journalled on the two arms is a bat rotatable with respect to the arms for movement about a bat axis parallel to the main axis. At least at one end the bat has a crank carrying a crank pin with a crank axis offset from but parallel to the bat axis. Fixed on the main frame is a circular guide symmetrical about a guide axis eccentric from and parallel to the main axis. A follower, like an eccentric strap, is mounted to rotate on the circular guide. A rod connection to the follower extends to a journal connection on the crank pin. Usually, the reel includes a number of similarly mounted bats, and all but one of the rods is connected to the follower by journal connections having their axes parallel to the main axis, the one follower omitting the pivot connection to the guide and being fixed relative thereto.
A harvester reel comprising a frame, a shaft, means on said frame for journalling said shaft for rotation relative to said frame about a main horizontal axis, a pair of axially spaced mounting arms fixed on and extending outwardly of said shaft, a bat, means on said arms for journalling said bat adjacent the outer ends of said arms for movement about a bat axis parallel to said main axis, a crank pin having a crank pin axis, means engaging said pin and said bat for fixing said crank pin to said bat with said pin axis eccentric from and parallel to said bat axis, a circular guide having a guide axis, means engaging said frame and said guide for fixing said guide on said frame with said guide axis eccentric from and parallel to said main axis, a follower journalled on said circular guide, and a rod having a connection to said follower and to said crank pin.
