ABSTRACT:
A chopping blade includes a mounting portion defining a mounting plane, and a working portion connected to the mounting portion. The working portion includes a leading edge, a trailing edge, and a body extending between the leading edge and the trailing edge. The body includes a first surface adjacent the leading edge and at least partially oriented at a first angle relative to the mounting plane, a second surface adjacent the trailing edge and at least partially oriented at a second angle relative to the mounting plane, and an intermediate surface extending between the first and second surfaces. The intermediate surface has a first portion extending from the first surface at an angle relative to the mounting plane that is steeper than the first angle, and a second portion extending from the second surface and joining with the first portion to form a peak.
