Rotary mower

Abstract

A rotary motor comprises an upper rotating collar section and a lower rotating disc, and mounted between the collar section and the disc a predetermined number of knife blades which are rotatable about their mounting and located toward the collar and disc periphery in a manner to prevent damage when the blade strikes loose stones and the like. The disc also includes an integral, radial, depressible spring strip for each knife blade for quick knife changes, suitable air ducts on its upper surface and at least one radially arranged vane on its underside. The mower further includes a saucer mounted underneath each collar section and disc, at least one predetermined lamination inside each saucer, and a plurality of suction slots or holes around the saucer perimeter to provide a vertical updraft and horizontal suction effect whereby the material being cut by the mower is elevated upwards for cutting purposes and wherein the windrows formed by the drum type mowers are widened in a set manner for more effective conditioning subsequent to mowing.
