ABSTRACT:
An automatic forage harvester shearbar-cutterhead clearance adjusting system includes motors connected to conventional left and right shearbar adjusting mechanisms. A knock sensor senses contact between the shearbar and the rotating knives of the cutterhead. A control unit including a programmed microprocessor controls the motors and, responding to signals from the knock sensors, automatically adjusts the shearbar-cutterhead clearance. The control unit prevents machine damage by responding to various fault conditions.
