ABSTRACT:
A rotary cultivator formed with vertically rotating pairs of transverse-ended ground-penetrating spoke-like end-bladed wheels. Such assembly now adds horizontal pairs of fixed cutter blades spaced respectively one outward from the peripheral path of the wheel-blades and the other radially inward therefrom, plus other laterally projecting blades extending into the "open-cage" formed by each pair of mutually-facing bladed wheels. Standing vegetation against which the cultivator is moved may be severed into segments, additionally miniaturized within the open-cage, and churned into the top soil upon penetration of the wheel blades. Trailing vines or weeds which might otherwise attach to and wind around the shaft are also cut off. Such-sub-unit of interacting cutter blades can be added to present rototillers, or be fabricated as part of the initial unit.
