Vegetation cutting apparatus having a frontal housing deck overlies at least three rotary blade cutters arrayed leftwardly, medially, and rightwardly for simultaneously cutting a continuous transversely extending swath and centifugally discharging the cuttings through a central and rearwardly longitudinally extending cuttings chute. The vertical shaft for each horizontal rotary blade carries a sheave; a belt transmission means, emanating from a powered gearbox, drives the respective blade sheaves and also a reversing sheave, the latter ensuring that the arrayed rotary blades direct vegetation cuttings toward the central discharge chute. A novel spring-loaded device maintains constant tension upon the circuitous belt transmission means.
