Abstract: A harvester is provided for mechanized harvesting of vine crops such as cucumbers. A harvester head is provided with a plurality of rollers, each of which comprises a cage structure rotatable about a central longitudinal axis, a rotatable shaft within the cage structure and extending generally parallel to but offset from the longitudinal axis of the cage structure, and a plurality of fingers mounted to the shaft and extending radially outward through the cage structure. Because the shaft and the cage structure rotate about offset axes, the extension of the fingers beyond the cage structure varies along the rotational arc of the roller. The rollers are preferably mounted to provide maximum extension of the fingers during lifting of the vine mat and crop. Belts on the forward roller are spaced apart to permit dispersion of soil picked up with the vine mat.
