PROBLEM TO BE SOLVED: To provide a leek harvester in which a relative position in the vertical direction of the tip side part of a ridge shoulder breaking unit and a conveyance unit is made adjustable, and thereby the harvest of the leek adapted to the shape and height of the ridge where the leek is cultivated is made possible.SOLUTION: As a working unit, a harvest unit comprises: a ridge shoulder breaking unit for breaking both shoulders of a ridge a digging-up unit for digging up a cultivated leek in the ridge where both shoulders are broken by the ridge shoulder breaking unit and an entry resistance is reduced and a conveyance unit for holding the leaf part of the leek dug up by the digging-up unit and conveying the leek to the rear. The ridge shoulder breaking unit, the digging-up unit and the conveyance unit are pivoted at base ends to a traveling machine body, respectively, and the tip sides are made integrally liftable. Also, the ridge shoulder breaking unit and the conveyance unit are made adjustable at a relative position in the vertical direction of these tip sides.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2016,JPO&INPIT
