Abstract
The present invention provides an apparatus that lifts, secures, splits and/or crushes tree stumps or other materials, particularly wooden or metal materials and other materials that may be present at an excavation site. The apparatus is characterized in part by a two pivot point design. A first pivot point allows for the pivotable operation of an engaging unit which grabs and lifts the tree stump. The engaging unit further acts a durable and secure support member for the tree stump during the splitting and crushing process. The second pivot point allows for the pivotable operation of a cutting device which facilitates splitting and crushing of the stumps.
