  • Patent number: 5595021
    Abstract: Improved turf units for assembling a natural turf playing surface in a stadium or the like. Natural turf units are provided which are transportable between first and second locations, the second location being for the growth and maintenance of the turf unit; the first location being a location for the performance of the desired activity. A fence section hingeably connected to the growing pan of the turf unit provides for maintenance of the top level of the plant growing medium at a significant height above the top of the side walls of the growing pan. A turf unit in accordance with the invention is used to assemble such a playing surface without removable parts. Also, the outer periphery of the fence extends outwardly beyond the outer periphery of the side walls of the growing pans such that, when the turf units are assembled adjacent each other to create the playing surface, large areas exist beneath the playing surface to provide adequate space for drainage of the field.
