  • Patent number: 5816334
    Abstract: An apparatus for simultaneously separating debris from topsoil and re-spreading the debris-free soil on the ground. The apparatus consists of a conventional, earth moving tractor to which a chassis is mounted and which carries a plurality of soil treating devices in series. The chassis includes a soil carrying and conveying paddle assembly mounted across the width of its front end which scoops up the debris laden soil off the ground. A conventional, vibrating table for separating the debris from the soil is mounted across the width of the chassis, adjacent to the paddle assembly, and the debris-laden soil is deposited onto the vibrating table from the paddle assembly. Once the vibrating table has separated the debris from the soil, the soil falls through the chassis' open bottom back to the ground, and the debris is ultimately moved to a conveyor assembly. The conveyor assembly carries the debris from the vibrating table and deposits it in a collection bin mounted across the back width of the chassis.
