ABSTRACT:
A special cultivating machine, lawn care apparatus and process are provided to properly prepare, efficiently condition, and gently cultivate the soil, turf and lawn in a uniform manner without uprooting, ruining, or damaging existing healthy plants and grass and without substantial thatching. The special cultivating machine, lawn care apparatus and process attain excellent seed and soil contact for virtually all soil compositions, textures, and conditions, and accurately follow the contour of the ground soil, turf, or lawn, regardless of mounds, hills, valleys, irregularities, clumps, and other soil conditions. The cultivating machine and lawn care apparatus has spring biased, rearwardly facing, scratching arms (cultivation fingers) which are reciprocatingly driven by a crankshaft. The crankshaft is smoothly rotated by a chain and sprocket arrangement. Desirably, the crankshaft and scratching arms can be raised or lowered by a height adjustment assembly to vary the depth and angle of soil penetration.
