Abstract
A harvesting machine includes a cutter head having a cutter bar for cutting crop from a ground surface and a rotatable reel located above the cutter bar. Reel arms of the reel each include a plurality of fingers thereon to engage the crop. The cutter head also has an actuator configured to adjust a pitch of the fingers with respect to the reel arms. A controller is operably connected with the cutter head and is configured to receive an input on a cutter head posture relative to the ground surface, with the input on the posture of the cutter head including one or more of a height of the cutter head or an angle of the cutter head relative to the ground surface. The controller operates the actuator to automatically control the pitch of the plurality of fingers based on the received input on the posture of the cutter head.
