Abstract: An implement and procedure for reconditioning and aerating turf is disclosed. The implement comprises a frame, a narrow plow member having a concave leading edge with a forward tip depending from the frame, and a pair of narrow blades declining at an angle from the frame and loosely engaging opposite sides of the plow member adjacent its tip. The blades are mounted in a particular manner and are provided with specially-shaped edges designed to provide the desired groove cutting action as the implement is pulled forwardly through the turf. The implement functions to cut and lift slivers of soil and sod and to deposit the same along a groove cut in the turf. Preferably, a series of parallel grooves are formed in the turf in a single pass, the widths and depths being determined by the nature and severity of the reconditioning or aerating problem being treated.

Abstract: A modular structure for supporting weight loads and traffic in extensively used turfgrass areas comprising a plurality of identical modules having open cells defined by vertical wall portions and a bottom wall. The modules are disposed in laterally adjacent interengaging interlocked relation to form the modular structure which is imbedded in the turfgrass area to a depth slightly less than the height of the module cells so that the upper edge portions of the cell side walls extend into the turfgrass to support and bear the weight and wear of traffic passing over the area.
