ABSTRACT:
A device (10) for working soil is disclosed in the preferred form including a grading portion (12) and a raking portion (32) of generally C-shapes. Specifically, the grading and raking portions (12, 32) are formed from planar, central sections (14, 34) and first and second, planar wing sections (16, 18, 36, 38) extending from the opposite ends thereof. The grading portion (12) includes a plurality of spaced, parallel blades (24) secured to the bottom surface of the body portion formed from a tubular beam (20) and a grading plate (22) and arranged at a nonparallel angle to the movement direction to serrate the soil. The blades (24) have elongated lengths greater than the thickness of the body portion and are spaced generally equal to their widths. The raking portion (32) includes a plurality of spaced, parallel, straight teeth (44) securred to a plate (40) and tilted at a forward angle to the movement direction. The lower ends of the teeth (44) are angled and are at the same level and coplanar with the bottoms of the blades (24) of the grading portion (12).
