  • Mower blade
    Patent number: 4426831
    Abstract: An elongated blade (21) for a rotary mower is fabricated from a nonrectangular blank (9) so that the lift portions (33, 34) formed on the trailing parts of the blade have radially outer peripheries (41, 42) which lie substantially on a circle (d) generated by the radially outer tips (46, 47) of the leading cutting edges (28, 29). This produces a blade with improved grass bagging characteristics due to greatly improved discharge of air entrained clippings.
