Ground track obliterating device

Abstract

A track obliterating device is disclosed that is particularly useful for obliterating the tracks on the ground made by a chemical applicator wagon. The device includes a mounting frame upon which a plurality of ground engageable track obliterating elements are mounted. The track obliterating elements are preferably coil spring teeth that are mounted on the mounting frame so as to be substantially aligned with the wheels of an applicator wagon so that the tracks made by such wheels are obliterated as the device is pulled in a forwardly direction behind the applicator wagon. The mounting frame is adapted to be attached to an applicator wagon or the like by a hitch that is pivotally mounted to the mounting frame so that the mounting frame can pivot about a vertical axis. The hitch can be a bifurcated arm pivotably mounted to the mounting frame at spaced points with a single tongue adapted to be connected to the applicator wagon or may include a pair of spaced rods each of which are pivotably mounted to the mounting frame. A pair of wheels is also mounted to the mounting frame forwardly of the obliterating elements, and a controller, such as a piston and cylinder, is connected between the hitch and the mounting frame to raise and lower the obliterating elements with respect to the ground.
