PROBLEM TO BE SOLVED: To provide a heavyweight harvest handling/conveying unit capable of conveying heavyweight harvests gathered by a harvesting machine onto a trailer traveling to the accompaniment of the harvesting machine, and capable of packing the harvests in cases and piling the cases, so as to convey and take out the harvests in a large amount.
SOLUTION: In this heavyweight harvest handling/conveying unit, the trailer 8 is made to travel to the accompaniment of the harvesting machine 1 for harvesting heavyweight vegetables C, and an endless conveyor 10 is extended from the trailer 8 to a position near to an operator M1 for the harvesting machine, so that the operator M1 drives and controls the endless conveyor 10 and makes the conveyor horizontally turn about. The endless conveyor 10 is driven by an external hydraulic outlet and has a control means 10a for changing its conveying speed. A roller conveyor 13 carries empty cases and has an inclination toward an operator M3 so as to make the case transferred by its own weight. A roller conveyor 14 transfers the cases which receive the harvests to a position where the cases are piled. A tractor 7 and the trailer 8 are operated by a remote controller 16 or made to be traveled on an area between ridges, so as to realize unmanned traveling. The endless conveyor 10 and the roller conveyors 13, 14 are each mounted on the tractor 7 or the trailer 8, after the conveyors are selected.
