ABSTRACT:
A rotary hoeing tool comprising a flat portion, or hoe-blade, furnished with a forward cutting edge and one or more teeth set apart, parallel with each other, interchangeable or otherwise and protruding downwards to the rear of the tool's cutting edge, designed to forestall compaction of the earth resulting from the action of the hoe-blade. The said flat portion or blade (4, 5 & 15) may be fixed direct to the flange (11) of the cultivator's rotor shaft (10) by way of a flat shank (2), or onto an L-shaped mounting connected to the flange (11) of the cultivator shaft (10). The teeth (6, 7, 8 or 22) may be incorporated directly into the flat portion or blade (4 or 5) part of the tool, or made fast to the L-shaped mounting independently of the actual hoe-blade.
