Abstract
A control system for a cutting reel unit includes a reel-to-bedknife clearance adjusting system. The reel-to-bedknife clearance adjusting system includes at least one actuator operatively connected between the reel and the bedknife, and a sound detector. A controller is signal-connected to the actuator and the sound detector and coordinates the reel-to-bedknife clearance adjustment. During adjustment, reel-to-bedknife clearance is reduced by the actuator until a contact sound between the reel blades and the bedknife is detected and signaled to the controller, which then reverses the actuator and increases the clearance by a pre-selected precise amount.
