ABSTRACT:
The machine is coupled to a standard tractor, and normally slides over the ground on a skid plate as the vehicle moves forward. A film roll is supported on the machine in a position to be unwound, and the film is progressively deposited on the ground behind the skid plate. Groove-forming structure under the skid plate are disposed centrally inward from the edges of the film roll, and following wheels depress the edges of the film into the groove. Scraper plates then move earth into the grooves, entrapping the edges of the film.
