Abstract

A device for dressing the contours of a lawn by moving dirt from high spots to low spots, comprising a frame with a grid attached to the frame and held in direct engagement with the surface of the lawn while being pulled by a vehicle. The grid has a plurality of elements forming an interlocking network that defines a multiplicity of holes. Each element has two surfaces that meet at an angle to form a dirt-scraping edge, moving some dirt upwardly into the bed of the grid. The dirt is moved with the grid until the grid is over a low spot whereupon the dirt will be deposited through the holes. The grid may optionally be attached to two or more brackets and bolted to the frame as a replaceable cartridge. The frame preferably accommodates a standard three-point hitch.
