A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.

A combine harvester including a cleaning shoe, having a tailings auger for collection of tailings, a tailings collection bin and apparatus for moving material from the tailings auger to the tailings collection bin.

The present invention relates to a method and system of conveying harvested material within or out of a combine harvester using positive air pressure. The invention provides for a lighter, simpler process of material handling by using positive air pressure to pneumatically convey harvested material. As compared to conventional methods, the present invention incorporates lighter weight components and fewer moving parts. Systems of the present invention have more flexible layouts than conventional methods, which allows for the incorporation of different material types, easier cleaning, and potentially greater ease for process automation.

Provided is a combine capable of harvesting an appropriate amount of grains according to a free capacity of a drier, while reducing trouble for a worker. A harvest amount sensor is capable of a first determination U1 for determining the grain storage amount intermittently during reaping traveling of a traveling vehicle body and a second determination U2 for determining the grain storage amount based on a manual operation during stopped state of the traveling vehicle body. A calculation section is configured to calculate the total harvest amount based on a first determination amount M1 by the first determination U1 and a second determination amount M2 by the second determination U2. A decision section is provided for deciding whether the total harvest amount has exceeded the target storage amount MI based on a requested grain amount requested by a drier, or not. An informing section is provided for effecting completion informing T3 if the decision section decides that the total harvest amount has exceeded the target storage amount MI.
