ABSTRACT:
A motor driven feed sharpener for raising and lowering a sharpening stone on a feed chopper. When the sharpening stone is lowered a cover plate opens and the sharpening stone engages the top of rotating feed chopping knives and sharpens the feed chopping knives as they are rotated thereby. When the sharpening stone is raised into the feed sharpener, a cover plate is automatically moved to close the opening between the sharpening stone and the knives to contain the chopped material within the feed chopping knife cylinder and to protect the sharpening stone from abrasion during normal feed chopping.
