ABSTRACT:
A system for executing a farming activity on a working area including one or more growing areas of crop items and harvesting tools and manipulators for harvesting crop items hanging by stems from their growth sources. The system includes a track extending substantially parallel to and in a spaced relationship from one or more of the growing areas of crops and a trolley driven along the track, the trolley including farm equipment for executing a farming activity on the growing areas of crops. One embodiment of a harvesting tool includes a base and a cutterhead mounted on the base, the cutterhead having (i) an array of fingers for accommodating the stem between a pair of adjacent fingers, the array having a substantially arcuate configuration and dimensioned so as to envelop at least the top portion of the crop item and (ii) a stem cutter for cutting the stem when accommodated by a pair of adjacent fingers. Another embodiment of a harvesting tool includes a manipulator for selectively harvesting the crop item, the manipulator detaching the crop item from its growth source during a displacement from an extended position in which it grips the crop item at its growth source to an retracted position and a stabilizer for stabilizing the growth source while the crop item is being harvested therefrom, the stabilizer assuming a growth source engaging position before the manipulator is displaced from its extended position to its retracted position.
