2. Description of the Related Art As is well known, a conventional combine harvester of this type has a structure in which all of the cut grain culms are supplied to a handling room of a threshing device to perform a grain removing process. Therefore, the threshing device requires a high threshing resistance due to a large threshing resistance in order to thresh the culms, but measures have been devised to process this with a small horsepower.

That is, the reaping device is composed of two first mowers and a second mower, the upper part of the grain culm is cut off by the first front mower and supplied to the threshing device, and the remaining plant part is taken by the second mower. That is what is cut and left in the field. In this way, the threshing device can reduce the amount of supplied grain culm by performing high-cutting with the fast mower and can continue the work in a state where the threshing load is relatively small.

Therefore, the second mower is provided behind the cutting pretreatment device to which the first mower is attached and below the conveyer conveyor device, but it must be adjusted up and down frequently in relation to the first mower. The narrow space makes the transmission extremely complicated.

[0005]

The second mower device in the combine is usually supported by a narrow space below and rearward of the pre-mowing treatment device due to the surrounding structure, and while being transmitted in that state. Moreover, it is required to be able to be adjusted frequently up and down. And
In the second mower, the transmission from the prime mover of the airframe has a complicated structure such as expansion and contraction because it moves up and down, and the transmission efficiency is poor in operation as well, and straw dust etc. is caught in the transmission and hinders smooth transmission. There were problems such as doing.

[0006]

The present invention takes the following technical means in order to solve the above problems. That is, a pre-mowing treatment device comprising a fast mower 1 provided at a low position in the front part, a scraping reel 2 supported above the scraper 2, and a scraping auger 3 for laterally collecting and collecting the harvested culm. Four
