Abstract

A cutter head for a harvester, with a cutterbar for cutting crop from a field, a reel with reel fingers which is disposed above the cutterbar, and a cross conveyor for transporting the cut crop to a rear discharge opening. The reel includes reel arms that can be driven about a rotating axis, reel finger carriers supported on the reel arms so they can rotate about the lengthwise axes of the arms, with reel fingers mounted thereon, and an externally powered actuator connected to an electronic control unit for adjusting the rotary angle of the reel finger carrier relative to the reel arms.
