ABSTRACT:
A row crop cultivator has a plurality of domed discs suspended in pairs from a suspension system in which the discs are firmly restrained against lateral movement relative to the crop row being cultivated but are free to move vertically to adjust to uneven conditions or obstacles of the ground. A generally cylindrical band is fixed to one side of each disc and has a smaller diameter than the disc diameter defining a cylindrical surface which rides on the surface of the ground and permits the disc to penetrate the soil only to a predetermined depth. The cylindrical surface if of sufficient width that it supports the disc in a floating manner over the ground and a uniform depth of cultivation is achieved, whereby damage to crops from excessive disc penetration is avoided.
