Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for digging root crops such as onions and carrots from a field.

[0002]

Conventionally, while traveling, the dug onion is discharged into a field, and then the onion is collected one by one or several onions are bound into one collection. Post-processing is performed, but there is a problem that the directions of the released onions are not uniform and it takes time to collect and bind.
