The base end is attached so as to be rotatable in the front-rear direction. A cutting lever link 287 is integrally fixed to the base end portion of the cutting clutch lever 39, one end of the cutting clutch wire 288 is connected to the cutting lever link 287, and the other end of the cutting clutch wire 288 is connected to the tension roller-like shape. The tension arm of the mowing clutch 242 is connected.

  With the above-described configuration, the cutting clutch lever 39 supported in the standing posture as shown in FIG. 10 is rotated around the lever fulcrum shaft 286, and the cutting clutch lever 39 is tilted forward of the machine body so that the handrail serves as a lever collapse stopper. The cutting clutch lever 39 is moved to the lying posture (the state shown in FIG. 11) to be brought into contact with the body 35, the cutting clutch wire 288 is pulled in a state of exceeding the cutting clutch fulcrum, the cutting clutch 242 is engaged, and the cutting drive belt 241 is operated. The reaping device 3 is configured to be tensioned. 11 is returned to the standing posture (the state shown in FIG. 10), the cutting clutch 242 is turned off and the cutting device 3 is stopped.

  That is, as shown in FIGS. 8 to 11, the threshing clutch lever 40 is disposed on the left side of the driver seat 42 via the left lever fulcrum frame 274. A cutting clutch lever 39 is arranged on the right side of the driver seat 42 via a right lever fulcrum frame 285. Shift levers 43 and 44 that are control levers for changing the course and moving speed of the traveling machine body 1 are arranged on the front end side of the side column frame 273 on the threshing clutch lever 40 side with respect to the driver seat 42. A left lever fulcrum frame 274 and a lever fall stopper 284 are provided upright on the rear end side of the side column frame 273. Further, among the seat frame 268 as a driver's cab on which the driver's seat 42 is installed, a handrail body 35 for getting on and off is fixed to a right lever fulcrum frame 285 forming a part on the right side of the seat frame 268. A base end portion of the handrail body 35 that extends from the right side surface of the right lever fulcrum frame 285 toward the left side and extends from the left side surface of the right lever fulcrum frame 285. The cutting clutch lever 39 is pivotally supported.

  Furthermore, with reference to FIGS. 9-11, the check structure of the cutting clutch lever 39 is demonstrated. As shown in FIGS. 9 to 11, a regulation member 120 that regulates the operation of the reaping clutch lever 39 according to the operation position of the threshing clutch lever 40 is provided. The restricting member 120 has a cutting restricting wire 121 that connects one end side to the cutting lever link 287 via a pin shaft 123 and a restricting link body 122 in which a long hole 124 is formed. The restriction link body 122 is connected to the other end side of the cutting restriction wire 121. The regulation link body 122 is connected to the threshing lever link 276 via a pin shaft 125 that is slidably inserted into the long hole 124. When the threshing clutch lever 40 is supported in the standing posture (the state shown in FIG. 10) in which the threshing device 9 is stopped, the reaping restriction wire 121 is supported in a tension state, and the reaping restriction lever 121 is pulled. It is configured to check the entering operation.

  That is, in the state where the threshing clutch lever 40 is supported in the standing posture (the state shown in FIG. 10), the cutting clutch lever 39 is maintained in the standing posture by the tension of the cutting regulation wire 121, and the forward tilting operation of the cutting clutch lever 39 is performed. When the threshing clutch lever 40 is operated to the clutch disengagement position, the clutch engaging operation of the reaping clutch lever 39 is prohibited by the restricting member 120 and the threshing device 9 is prevented. The reaping device 3 is also configured to be stopped and maintained when is stopped. Further, when the threshing clutch lever 40 is supported in the lying posture (the state shown in FIG. 11) in which the operator enters and operates the threshing clutch lever 40 to operate the threshing device 9 and contact the lever lying stopper 284. The clutch lever 39 can be tilted forward, and when the threshing device 9 is in operation, the operator can enter and operate the cutting clutch lever 39 to operate the cutting device 3.

  As shown in FIGS. 1 and 8 to 11, the reaping device 3, the threshing device 9, and the engine 7 are mounted on the traveling machine body 1, and the threshing apparatus 9 is disposed in the vicinity of the driver seat 42 installed in front of the traveling machine body 1. In the combine in which the threshing clutch lever 40 for turning on and off the power transmission of this and the cutting clutch lever 39 for turning on and off the power transmission to the reaping device 3 are installed, the threshing clutch lever 40 is disposed on the left side of the driver seat 42, A cutting clutch lever 39 is disposed on the right side of the driver seat 42. Therefore, by arranging the reaping clutch lever 39 and the threshing clutch lever 40 separately on the left and right sides of the driver seat 42, erroneous operation of the reaping clutch lever 39 by the operator can be prevented. Further, when the rod-shaped clutch operating body 283 for connecting the threshing clutch 233 to the threshing clutch lever 40 is provided, the rod-shaped clutch operating body 283 is linearly moved in the front-rear direction by turning on and off the threshing clutch lever 40 tilted in the front-rear direction. The threshing clutch 233 can be controlled to be turned on and off, and a manual operation mechanism (such as the clutch operating body 283) of the threshing clutch 233 disposed at a remote position with respect to the threshing clutch lever 40 can be configured at low cost and in a compact manner.

  As shown in FIGS. 8 to 11, speed change levers 43 and 44 that are control levers for changing the course and moving speed of the traveling machine body 1 are arranged on the threshing clutch lever 40 side with respect to the driver seat 42. Therefore, since the operator can operate the cutting clutch lever 39 with the right hand while operating the speed change levers 43 and 44 by using the left hand, the operator performs the steering operation with the left hand and the cutting device 3 with the right hand. Can be driven or stopped as required.

  As shown in FIGS. 8 to 11, a regulation member 120 that regulates the operation of the harvesting clutch lever 39 according to the operation position of the threshing clutch lever 40 is provided, and when the threshing clutch lever 40 is operated to the clutch disengagement position, The clutch engaging operation of the reaping clutch lever 39 is prohibited by the restricting member 120. Therefore, when the threshing clutch lever 40 is supported at the cutting operation position, the entering operation of the reaping clutch lever 39 is restrained. Accordingly, even if an attempt is made to enter and operate the harvesting clutch lever 39 in a situation where the threshing device 9 is not activated, the entry operation of the harvesting clutch lever 39 cannot be performed, and therefore the harvesting in a situation where the threshing device 9 is not activated. The operation of the device 3 can be prevented.

  As shown in FIGS. 8 to 11, a handrail body 35 is fixed to the right side of a seat frame 268 as a driver's cab on which the driver's seat 42 is installed, and the cutting clutch lever 39 is rotated around the handrail body 35. It is pivotally supported. Therefore, the support member for pivotally supporting the cutting clutch lever 39 is formed by using the handrail body 35 provided on the left side of the seat frame 268, thereby reducing the number of components of the supporting structure such as the cutting clutch lever 39. In addition, the cost of the support structure such as the cutting clutch lever 39 can be reduced.
