Abstract
A tub grinder is used for grinding industrial wastes, including large stumps, lumber chunks and the like. A cover member is pivoted alongside the tub, and is made in two sections. An upright frame section is pivoted near a plane along the bottom of the tub, and extends upwardly to a level at or adjacent to the top of the tub. A cover section is pivotally mounted to the upright frame and can be adjusted about a generally horizontal axis from a generally horizontal position to an upwardly extending position. The upright frame can be tilted outwardly so that the cover section is out of registry with the tub to permit the tub to be loaded.
