Abstract
An apparatus and method for calibrating the reel of an agricultural windrower, wherein a programmable control module in connection with a signal operated device in operative control of a variable displacement pump operable for controlling operation of the reel, is programmed as part of an automatic calibration routine for directing signals to the device having different values, for rotating the reel at two different speeds. The controller will then determine a characteristic algorithm or relationship between reel speed and signal value which will be predictive of reel speeds which will be achieved for a range of signal values.
