ABSTRACT OF THE DISCLOSURE Apparatus for tilling, weeding and generally working soil comprises a blade having a leading planar portion with ends. This portion declines forwardly from the horizontal along a long axis and includes a broad, slightly curvilinear leading edge disposed in the plane of the leading portion. The blade is strengthened by means of a trailing portion extending rearwardly from the leading portion and downwardly along the long axis to define a reinforcing gusset. A tang in the form of a U-shaped in- verted channel, centrally disposed on the trailing portion, further reinforces the blade by means of trailing edges converging inwardly and rearwardly from the ends to the channel and joining corresponding side walls of the channel at curvilinear gussets. The blade structure is non-ggressive which forces fewer rocks and stones to the surface and provides a flat, shallow cut that remains uniform despite blade wear.
