ABSTRACT:
A rotary mower in which grass cutting and collection of cut grass particles is achieved with a relatively low blade tip speed. A cutting blade is mounted for rotation about a vertical axis within a symmetrical expansion type mower housing in which the expansion top wall has a substantial rise to a discharge opening vertically above the cutting blade. The housing has a continuous exterior side wall surrounding the cutting blades and extending above the sail portion thereof. The sail portions of the blade trailing the cutting edges have substantial inward and upward rake angles which result in mechanical throwing of the grass and a pumping effect results from the housing and blade configuration. In certain embodiments, the cutting edges may be swept back at an angle with respect to the blade center line and the blade diameter may be selected to aid in effective cleaning of cut grass particles from the blade.
