ABSTRACT:
Disclosed are rotary cutting assemblies for cutting growing vegetation with a tough whirling flail. The assemblies generally comprise an elongate lineal shaft extending along and powerably rotatable about a vertical-axis, a horizontal base-plate in co-rotatable association with the shaft lower part, retainer means attached to the base-plate, and an elongate horizontal flexible flail extending radially outwardly from the retainer means along a horizontal-axis. For the purposes of promoting vegetation cutting action as the flail rotates about the shaft, and consistent with operational safety, the flail comprises a central-core along the horizontal-axis of a tough flexible resinous material and an external-contour of varying cross-sectional size. Preferably, the external-contour is provided by prominent protuberances surrounding the central-core and which enhances vegetation cutting without danger of inflicting injury to the operator.
