[Problems to be Solved by Prior Art and Invention]

 In general, some of the combine harvesters of this kind are provided with a step for getting on and off at a position lower than the floor surface of the driving operation section in order to improve the getting on and off property. However, since the conventional boarding / alighting step is provided with a leg-shaped foot hanging member and a foot hole at the lower position of the boarding / alighting section, it is difficult to get in and out of the board while getting in and out. However, it was difficult to get into the field of view, and it was forced to take an uncomfortable posture such as searching for the step position with a foot, which made it impossible to secure a good boarding / alighting property. Further, when the combine harvester has a so-called hopper specification and is provided with an auxiliary paddy receiving floor below the hopper, the driver appropriately moves to the auxiliary paddy receiving floor from the driving operation unit to perform the paddy bag exchange, etc. In the past, however, workability and work efficiency were problems because they had to move down to the field and then moved to the auxiliary paddy receiving floor.

[0003]

[Means for Solving the Problems]

 The present invention was devised in view of the above circumstances to provide a step structure for getting on and off a combine, which can eliminate these drawbacks. While a step for getting in and out of the floor of the operation part is provided, a work posture that projects to the outside of the machine and a storage posture along the outside of the machine are provided below the hopper that is arranged behind the operation control part. In a combine with a paddy receiving floor that can be freely swung and transformed, the stepping-on / off steps are provided in a step-like shape with respect to the floor surface of the operation part, and the left / right width of the stepping step is set within a range that does not protrude from the machine width. The width is set wide, and further, the front and rear width of the step for getting on and off is set so that the rear end of the step reaches the position near the front end of the auxiliary paddy receiving floor. With this configuration, the present invention makes it possible not only to significantly improve entry / exitability, but also to improve workability and work efficiency.
