ABSTRACT:
The disclosure embraces an improved blade arrangement for a power mower which includes four blade arms mounted on a shaft together with a curved plate which is mounted on the same shaft a selected perpendicular distance from the blades; air deflection surfaces are provided both on the trailing edge of each of the blades as well as on the plate so that, when in use, the resulting noise produced by the rotating blades will be reduced.
