ABSTRACT:
Apparatus is described for cutting corn stalks and other plant stems in the field after harvesting. The apparatus is towed behind a tractor and includes: (a) a frame, (b) a rotatable cutter wheel carried by the frame and including a plurality of transverse cutting knives around its periphery, and (c) a plurality of spaced-apart, vertically oriented rotatable coulters carried by the frame. The transverse knives cut stalks which are longitudinally oriented on the ground and the coulters cut stalks which are transversely oriented (i.e., cross-wise) on the ground. A sweep member can be included at the leading end of the frame for loosening the butts of corn stalks from the ground.
