Abstract
Abstract A power driven circular saw blade for cutting brush is extensible with scythe tips mountable diametrically thereon for cutting grass. The saw blade is horizontally mounted in a recess defined between forwardly extending sides of a wheeled cart, the sides acting as brush guides and stabilizing against a directional pull generated by the rotation of the saw blade in heavy brush, as well as providing a safety factor in shielding the operator and others from the rotating saw blade and scythe tips, and matter flung thereby.
