PROBLEM TO BE SOLVED: To solve a problem that a lateral width of a machine body becomes large since a reverse rotation mechanism is provided to be coaxial with a driving shaft (a reaping input shaft) of a conveyance elevator and that maintenance work becomes troublesome since the reverse rotation mechanism is configured by a bevel gear and has a complicated structure.SOLUTION: A combine-harvester is provided with a reverse rotation mechanism 20 which is branched from the midway of a transmission route for driving a reaping device 4 to rotate normally by rotation power of an engine 21 and transmits to the reaping device 4 by reversing a rotational direction directed by the engine 21. The reverse rotation mechanism 20 is constituted of a pair of upper and lower side spur gears 25, 26 respectively provided on a reaping input shaft 22 provided on a conveyance elevator 14 and a reverse rotation input shaft 24 in parallel with the reaping input shaft 22, and the reaping input shaft 22 and the reverse rotation input shaft 24 are provided on a reaping supporting part 27 which supports the conveyance elevator 14 to ascend and descend.SELECTED DRAWING: Figure 2 |
