Abstract
A machine that quickly lays a cover over a freshly seeded area and at the same time anchors the cover to the ground. The cover helps prevent moisture from escaping from the ground and holds the seeds in place during watering the area, during heavy rains and/or during wind storms. The ground cover is a blanket in the form of a ribbon of considerable length that is rolled onto a spindle and may consist of straw or the like or the equivalent thereof retained between a pair of porous sheet, mesh or netting members or suitably attached or adhering to single sheet of the same and which preferably is biodegradable. The ribbon is payed out from the spindle as the machine traverses the area to be covered. Apparatus on the machine anchors the laid in place ribbon to the ground as it is placed on the ground by driving pins through the ribbon into the ground and/or by forming and pressing a “V” shape formation in the ribbon an adjustably variable selected depth into the ground.
