The chip breaker is provided with a chip breaker plate having a rearwardly and downwardly acute angle chip breaking front edge which is disposed closely adjacent a rotary cutter so as to engage the spiral chips made by the rotary cutter during a cutting operation and to break up the chips and separate them from the rotary cutter, and deposit them away from the rotary cutter work area.
