Conventionally, a mowing header is mounted on the front side of the threshing section via a feeder house so as to be able to move up and down, and the culm stalked by an uncut culm raking reel is cut by a cutting blade and raked. There is a technique for performing a harvesting operation of feeding a feeder house from a garage auger. However, when a bearing bracket that supports the uncut culm raking reel is slidably provided on the lift arm, and the bearing bracket is slid by a hydraulic cylinder attached to the lift arm, and the reel is moved back and forth, the bracket and the There is a problem that a piece of straw or the like is clogged between the lift arms and causes a malfunction.
In addition, since the center distance of the reel drive chain changes due to the longitudinal movement of the reel, it is necessary to have an automatic tensioning structure in which a tension arm is swingably provided by a spring, so that the tension structure can be simplified and lightened easily. There is a problem that cannot be obtained. Also, it is necessary to provide left and right hydraulic cylinders on the left and right lift arms supporting both sides of the uncut culm scraping reel, to control the two hydraulic cylinders to move the reel back and forth. In addition to being unable to easily reduce costs and the like, there is a problem in that the left and right sides of the reel have a difference in the amount of front-rear movement and are likely to be deformed and damaged. In addition, a long hydraulic pipe or the like is required in connection with the left and right hydraulic cylinders, and there are structural and handling problems such as a reduction in the number of parts, a reduction in weight, prevention of oil leakage, and attachment / detachment of the reaper.

As apparent from the above embodiments, the present invention provides a cutting header (20) in front of a threshing unit (4) via a feeder house (21), and a non-cutting culm pulling reel (20). 22) and cutting blade (23) and scraping auger (2)
4) In the combine for attaching the cutting header (20) to the cutting header (20), the rear of the lift arm (66) for pivotally supporting the uncut culm raking reel (22) at the front is cut via the fulcrum frame (70). And a forward / backward moving cylinder (74) attached to the mowing header (20) is connected to a fulcrum frame (70). The fulcrum frame (7) is connected to the fulcrum frame (70) by the cylinder (74).
0) is rocked back and forth to move the reel (22) back and forth,
There is no need to slide the shaft support of the reel (22) of the lift arm (66), and the structure for moving the reel (22) back and forth can be simplified and the reliability can be easily improved. This makes it possible to easily eliminate malfunctions in the forward-backward movement caused by the movement.
