(under the class definition) Apparatus in which a member, disposed entirely above ground is moved above and adjacent the earth's surface into contact with the sides of plants or partially buried objects to impinge or thrust against said plants or objects in order to dislodge them from the soil.
(1) Note. An underground cutter may or may not be provided to sever plant roots.
(2) Note. The beater or impeller may be inclined at an angle to the line of draft in order that the unearthed objects (usually bean vines) may slide along the beater or impeller into a windrow.
(3) Note. The beater or impeller may be rigidly supported on a frame or may be movable with respect to said frame.
(4) Note. Included herein are those structures disclosed as adapted for the purpose of moving small stones along the surface of the ground in order to gather or windrow said stones because of the similarity of said structures to the apparatus provided for by this subclass definition and the likehood of said structures engaging and unearthing stones which are partially embedded in the ground.

19, for unearthing apparatus which includes a member disposed above ground and extending to a point above and immediately adjacent the earth's surface, said member being generally transverse or inclined relative to the line of draft in order to engage and impell unearthed objects on the ground and push them either forwardly into piles or laterally into windrows.
