ABSTRACT:
A material chapping machine, such as a forage harvester, includes a system for automatically controlling the movement of a sharpening stone to sharpen the knives of a rotating cutterhead. Motors move the stone radially towards and away from the cutterhead and laterally across the cutterhead. Contact between the stone and the cutterhead is sensed by knock sensors. The motors are controlled by a programmed microprocessor.
