ABSTRACT:
A cultivator comprises a handle at one end of which is a plurality of dished discs, the dishing of the discs being opposed about a center point. The shaft on which the discs are mounted is bent through an angle at substantially a mid point such that by running the discs through soil, the discs cultivate the soil. The discs are mounted in two groups of two discs each. The groups are separated from each other by a curved spacer mounted on the shaft over the angled portion thereof.
