<P>PROBLEM TO BE SOLVED: To provide a combine harvester capable of driving a harvesting section to rotate normally and reversely while preventing the operation of a normal rotation clutch and a reverse rotation clutch both in the engaged state, with a simple structure from the viewpoint of linkage between the clutch and a clutch operating device. <P>SOLUTION: The combine harvester includes the normal rotation clutch for transmitting normal rotation driving force to the harvesting section, and the reverse rotation clutch 41 for transmitting reverse rotation driving force to the harvesting section. A normal rotation clutch operating device 52 for switchingly operating the normal rotation clutch is provided separately from a reverse rotation clutch operating device 54 for switchingly operating the reverse rotation clutch 41. The combine harvester further includes a restraining mechanism 70 switching to an acting state of restraining the switching operation of the reverse rotation clutch 41 into the engaged state when the normal rotation clutch is in the engaged state, and switching to a release state of releasing restraint when the normal rotation clutch is in the disengaged state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
