PROBLEM TO BE SOLVED: To provide an operation device of a combine, which can maintain a position of a gear shift lever for shifting the gear of a transmission moving to a low speed position.SOLUTION: A combine is provided in which: a front side transmission unit (FD) for transmitting a driving force of a reaping device (4) to a feed chain (34), and a rear side transmission unit (BD) for transmitting a driving force of a threshing device (3) to the feed chain (34) are provided; the front side transmission unit (FD) includes a front side clutch (60) for connecting and disconnecting the transmission from the reaping device (4) to the feed chain (34), and a front side gear-box (50) provided at the downstream side of the transmission more than the front side clutch (50); a belt (61) of the front side clutch (60) is wound around a pulley (21A) for taking out the driving force of the reaping device (4) and a pulley (51A) supported in an input shaft (51) of the front side gear-box (50); and a tension arm (62) for switching the tension of the belt (61) between a tension state and a relaxation state is rotatably supported by a support shaft (53) provided between the input shaft (51) and an output shaft (52) of the front side gear-box (50).SELECTED DRAWING: Figure 4 |
