Abstract: The combine may include a threshing tank that is configured to store a threshing product obtained by the threshing device and includes a lower tapered portion formed in a bottom portion. A bottom screw is provided inside the lower tapered portion and configured to discharge the threshing product from the threshing tank. A threshing discharge device is connected to the bottom screw and configured to convey the threshing product from the bottom screw and discharge the threshing product in a body outward direction. The threshing tank includes an inspection port formed in a bottom section of the lower tapered portion, and a lid configured to open and close the inspection port, and the lid opens and closes by swinging upward and downward about a swing axis that is not parallel with a screw axis of the bottom screw.

Abstract: 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.

Abstract: A lid is supported so as to be open and close by swinging upward and downward about a swing axis that is not parallel with the screw axis of a bottom screw.

Abstract: A transmission apparatus for a tractor is operable to transmit a forward drive force in a wide speed changing range to the traveling device and which is operable also to transmit a reverse drive force to the traveling device. A planetary transmission section is configured to output the forward drive force in whichever case a hydrostatic stepless speed changing section is speed-changed to a forward rotation speed change state or a reverse rotation speed change state. A low speed transmission clutch couples a low speed side speed changing gear to a counter shaft to be rotatable therewith. A high speed transmission clutch couples a high speed side speed changing gear to the counter shaft to be rotatable therewith. A reverse transmission clutch couples a reverse transmission gear to an output shaft to be rotatable therewith.

Abstract: Disclosed is a transmission apparatus for a tractor which is operable to transmit a forward drive force in a wide speed changing range to the traveling device and which is operable also to transmit a reverse drive force to the traveling device in an inexpensive manner and with good transmission efficiency. A planetary transmission section (30) is configured to output the forward drive force in whichever case a hydrostatic stepless speed changing section (11) is speed-changed to a forward rotation speed change state or a reverse rotation speed change state. A low speed transmission clutch (45) couples a low speed side speed changing gear (41), meshed with a low speed side output gear (31) of the planetary transmission section (30), to a counter shaft (44) to be rotatable therewith.
