ABSTRACT:
A machine for harvesting crops which grow as stalks or spears such as asparagus includes a frame supported by wheels to enable moving the frame along the ground, a stalk sensing mechanism for sensing stalks of a predetermined height, and a cutting and stalk grasping mechanism which is rotated into a cutting position adjacent each stalk sensed by the sensing mechanism. When the cutting and grasping mechanism reaches the cutting position, holding plates or pads move to secure the stalk therebetween and then a cutting element cuts the stalk below ground level. The operation of securing the stalk between the holding pads also serves to align the cutting element for cutting the stalk. The holding pads then elevate the stalk and ultimately spread apart above a stalk conveyor mechanism to allow the stalk to drop onto the conveyor. The stalk is then carried by the conveyor mechanism to a holding bin where it is deposited along with other stalks in a uniform orientation.
