<p>PROBLEM TO BE SOLVED: To provide a root crop harvester capable of avoiding a low-position selecting operation to become heavy burden on a selection transport device for adjusting the discharge drop of a transfer terminal end by an inclining operation.SOLUTION: A root crop harvester is constituted to comprise an extraction transport device (24), a selection transport device (87), a housing container mounting member (85) and a recovery stand (115). The root crop harvester further comprise a rising seat (202) for receiving the bottom of a housing container (97), a telescopic support device (201) for supporting the rising seat (202) telescopically over the recovery stand (115), and a yield sensor (U) for detecting the quantity of the contained crop of the housing container (97). The root crop harvester further comprises a control unit (221) for reducing the telescopic support device (201) in accordance with the detected housed crop quantity of the yield sensor (U) thereby to move down the rising seat (202) in conjunction with the yield, so that the work height of the selection transport device (87) can be retained.</p> |
