Description

  The present invention relates to a harvesting and harvesting machine in which a traveling vehicle body provided with a pair of left and right traveling devices is provided with a boarding operation unit covered with a cabin and a harvesting conveyance unit that harvests and conveys crops backward.

  In this type of harvesting and harvesting machine, conventionally, as applied to a combine harvester as an example of a harvesting and harvesting machine, the cabin is supported by a driver's cab having a width substantially equal to the lateral width of the traveling vehicle body. Is narrower than the driver's cab and is located at the center position in the lateral width direction of the traveling vehicle body, and is located on the left and right sides of the cabin in the state of being located laterally outside of the cabin. There is one in which a step portion that is continuous on substantially the same plane as the operation portion step) is formed (for example, see Patent Document 1). In Patent Document 1, a ladder for getting on and off is provided on the laterally outer sides of the left and right step portions.

JP 2000-37134 A

  In the above-described conventional configuration, since the step portions are formed on the left and right sides of the cabin, for example, the driver can check the status of work behind the vehicle body, perform maintenance work on each portion, etc. while the driver is on the step portion. Although there is an advantage that it can be done without getting off the traveling vehicle body, in the above conventional configuration, the cabin width is narrower than the traveling vehicle body width, so the living space inside the cabin is narrow and the driver operates There is a disadvantage that the comfort of is reduced. In particular, if the cabin is equipped with a cabin that has doors for getting in and out on the left and right sides and the interior is closed, the cabin interior space of the driver becomes narrower when the cabin width is reduced. May be difficult to do.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a harvesting and harvesting machine that allows a driver to perform a good driving operation inside a cabin while allowing the driver to perform various operations without getting off the traveling vehicle body. There is in point to do.

  A harvesting and harvesting machine according to the present invention is provided with a boarding operation unit covered with a cabin and a harvesting conveyance unit that harvests a crop and conveys it to the rear on a traveling vehicle body having a pair of left and right traveling devices.
