摘要： A wheeled trailer for installing a perforated film erosion barrier from a perforated foil supply roll into the earth and along an elongated furrow path. The wheeled trailer includes frame means for supporting the system for movement along the path, with a plow shoe being disposed forwardly of the frame to create a open furrow to receive one edge of an elongated perforated film, and with a pivotal boom being provided at the rear portion of the frame for supporting a furrow-covering disc. A hydraulic ram and cylinder are provided for arranging the path of the furrow-covering disc, with the furrow-covering disc depositing soil into the furrow for covering and burying one edge of the elongated perforated film.
