(1) The problems corresponding to the background art (1) are as follows.
In the above conventional configuration, since the fuel tank is merely used as a simple work table, it is difficult to perform maintenance work, particularly cleaning and inspection work of a handling room in a tall and large threshing apparatus. It was.

By the way, if it is the structure provided with a grain tank as a grain storage device which stores the grain obtained by the threshing process, in order to support an unloader etc. for a grain tank and a grain discharge, it is large in supporting strength. Since several support | pillars exist at intervals in the front-back direction, it was considered using these support | pillars to provide a work bench in the high position between a threshing apparatus and a grain tank. However, if it is a structure provided with the storage hopper, since the several support | pillar which supports the above grain tanks does not exist, the structure cannot be applied as it is.

Therefore, in a combine having a storage hopper, it has been desired that maintenance work such as a threshing device can be easily performed without complicating the support structure.

(2) The problems corresponding to the background art (2) are as follows.
