ABSTRACT:
A machine for harvesting crops which grow as stalks or spears such as asparagus. The machine includes a frame having wheels to carry the frame along the ground, a stalk sensing mechanism for sensing stalks of a predetermined height in a certain pathway, and a cutting mechanism which is rotated into a cutting position beside each stalk sensed by the sensing mechanism. When it reaches the cutting position, a portion of the cutting mechanism is moved transversely of the pathway to cut the stalk below ground level. Substantially simultaneously with the cutting of a stalk, a grasping mechanism seizes the stalk and, coincident with the rotation of the cutting mechanism, carries the stalk to a holding bin.
