Abstract
A rotary cutting blade for rotation about a fixed axis. The cutting blade has a generally rectangular planar body section having first and second ends and defining long and short edges. Each end of the cutting blade has both a downwardly oriented (leading) lifting and cutting member, and an upwardly oriented (trailing) lifting member. The downwardly oriented cutting member has a generally flat sharpened section oriented generally parallel to the plane orientation of the body section, and perpendicular to the rotational axis of the blade. The cutting blade can be re-sharpened without removal from a mower or other device.
Claims14
A cutting blade adapted to rotate about a fixed axis comprising:
- a. a substantially planar body member having a first end and a second end, and substantially parallel first and second sides;
- and
- b. a downwardly extending planar member disposed along said first side and defining a distal edge, wherein said downwardly extending planar member is oriented at first acute angle relative to said planar body member and has a substantially flat surface along said distal edge.
The cutting blade of claim . wherein said first acute angle is approximately 37 degrees.
A cutting blade adapted to rotate within a substantially horizontal plane about a substantially vertical axis comprising a substantially planar body member having a first end and a second end, and substantially parallel first and second sides, wherein a portion of said first side extends downwardly from said substantially planar body member at a first acute angle relative to said substantially horizontal plane.
A cutting blade adapted to rotate within a substantially horizontal plane about a substantially vertical axis comprising a substantially planar body member having a first end and a second end, a first side and a second side, a bore adapted to receive a rotary shaft approximately equidistant between said first and second ends, and defining a first leading edge along said first side between said first end and said bore and a second leading edge along said second side between said second end and said bore, wherein a portion of said first and second leading edges extend downwardly from said substantially planar body member at a first acute angle relative to said substantially horizontal plane.
