Abstract
Official abstract text for this publication.
A mower blade includes two symmetrical body portions disposed on either side of an axis of rotation, wherein each body portion includes a straight leading edge having a first sharpened edge formed along at least a portion of the leading edge, and a curved trailing edge having a second sharpened edge formed along at least a portion of the trailing edge, so that each body portion tapers to a rounded end.
First claim
Opening claim text (preview).
What is claimed is: 1. A mower blade, comprising: two symmetrical body portions disposed on either side of an axis of rotation, each body portion including; a straight leading edge having a first sharpened edge formed along at least a portion of the leading edge; a curved trailing edge having a second sharpened edge formed along at least a portion of the curved trailing edge, and a rounded end portion defining a midpoint at a distal end of each body portion, a sharpened curved portion between the straight leading edge and the midpoint, and a curved trailing portion between the midpoint and the trailing edge; wherein the two symmetrical body portions include a longitudinal axis, wherein each straight leading edge is parallel to and offset from the longitudinal axis, and each body portion tapers toward the rounded end portion. 2. The mower blade of claim 1 , wherein each body portion includes a lift feature. 3. The mower blade of claim 2 , wherein each lift feature comprises a twisted region. 4. The mower blade of claim 3 , wherein each twisted region is twisted about the longitudinal axis. 5. The mower blade of claim 3 , wherein each twisted region is twisted about an axis substantially parallel to the longitudinal axis. 6. The mower blade of claim 2 , wherein each lift feature comprises an air foil. 7. The mower blade of claim 2 , wherein each curved trailing edge tapers toward the longitudinal axis. 8. The mower blade of claim 7 , wherein each lift feature comprises a twisted region. 9. The mower blade of claim 8 , wherein each twisted region is twisted about the longitudinal axis. 10. The mower blade of claim 8 , wherein each twisted region is twisted about an axis substantially parallel to the longitudinal axis. 11. The mower blade of claim 7 , wherein each lift feature comprises an air foil.
