Zusammenfassung: | PROBLEM TO BE SOLVED: To automatically control the vertical motion of a harvesting part attached to a mobile machine in a state enabling the control of vertical motion interlocked with the height detected by a ridge or furrow height sensor. SOLUTION: This head-forming vegetable harvester 1 has a mobile machine and a harvesting part 9 attached to the machine and vertically movable in a manner controlled by a controller. (1) A ridge height sensor 13 contacting with the upper face of a ridge holding a grown head-forming vegetable and detecting the height of the ridge is placed at the front part of the harvesting part 9 and the harvesting part 9 is automatically lifted or lowered with a controller interlocked with the ridge height detected by the ridge height sensor 13. (2) A furrow height sensor 13a contacting with the furrow between the head- forming vegetable growing ridges and detecting the height of the furrow is placed at the front part of the harvesting part 9 and the harvesting part is automatically lifted or lowered with a controller interlocked with the furrow height detected by the furrow height sensor 13a to harvest the head-forming vegetable at the optimum height. |
