This is a characteristic configuration. The operation and effect of this characteristic configuration are as follows.

[0005]

Operation: That is, since the cut culms are distributed to the left and right, and each grain culm is processed by the pair of left and right handling cylinders of the threshing device, the threshing ability is higher than the conventional one in which the threshing processing is performed with only one handling cylinder. Will be high. Further, since the transmission mechanism is arranged by utilizing the space portion formed below one of the handling cylinders, it is not necessary to newly provide a special space portion for installing the transmission mechanism.

[0006]

Therefore, even if the mowing work is performed at a higher speed than the conventional one, that is, even when the vehicle speed is higher than the conventional one, a large amount of two grain culms are introduced into the pre-mowing processing section. Since the threshing process is divided into two parts and each threshing process is carried out by different handling cylinders, the work efficiency of the mowing threshing work becomes extremely high because the cutting work can be sufficiently performed at high speed. Furthermore,
As a structure for that purpose, since a pair of handling cylinders are provided to the left and right, the horizontal width of the machine may be slightly larger than before, but the front-rear length and height of the machine can be sufficiently suppressed, and the transmission mechanism Since it can be arranged by utilizing the space below the single handling cylinder, the entire machine can be made compact for threshing performance.
