PROBLEM TO BE SOLVED: To provide a combine including a grain tank having a lage storage capacity, capable of conveying grains easily.SOLUTION: A combine includes: an upstream side grain fixed-amount delivery device (81A) arranged on a position on the upstream side in the air sending direction between the grain tank (5) and the grain conveying air path (4), for receiving grains in a grain tank (5) from an upstream side reception port (89A) and supplying the grains into a grain conveying air path (4); and a downstream side grain fixed-amount delivery device (81B) arranged on a position on the downstream side in the air sending direction between the grain tank (5) and the grain conveying air path (4), for receiving grains in the grain tank (5) from a downstream side reception port (89B) and supplying the grains into the grain conveying air path (4). A mouth width (91A) of the upstream side reception port (89A) is formed larger than a mouth width (91B) of the downstream side reception port (89B). |
