[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operator's mirror mounted on a combine.

[0002]

[Prior Art]

 With conventional self-propelled combine harvesters, it is difficult to see the weeding condition by the weeding plate on the opposite side of the driver's seat from the driver's seat during mowing work, and it is not easy to see the rear of the same side of the aircraft when traveling backwards. The person must stand in the driver's seat when reaping and visually check the condition of the weeds, or lean out to check the rear of the fuselage.

[0003]

[Problems to be solved by the device]

 As described above, the operator has to stand up or lean out when cutting or moving backwards, and becomes tired.Therefore, the present invention can be performed while the operator sits in the driver's seat. In addition to making it possible to visually check the grass condition, and making it easier to see the rear of the aircraft on the opposite side of the driver's seat when moving backward, this is intended to be possible with a single mirror.

[0004]

[Means for Solving the Problems]

 Therefore, in order to provide the above-mentioned driver's mirror, the present invention provides a mirror at the upper left end of the mowing section on the opposite side of the driver's seat, and the mirror surface is oriented vertically by turning the threshing clutch on and off. It is possible to rotate approximately 90 degrees in the lateral direction about the attachment axis, and the raising and lowering operation of the mowing section lowers the mowing section to cut the clutch when engaging the clutch. The weeding condition of the plate can be visually checked, and the rear part on the left side of the fuselage can be visually checked through the mirror surface when the mowing portion is raised and the clutch is disengaged and the vehicle is moving backward.

[0005]

[Action]

 As a result, when the reaping section is lowered to the reaping position during the reaping work, and the threshing clutch is operated to activate the reaping section and the threshing section, the mirror attaches its mirror attachment shaft to the operation. Rotating in the lateral direction around the axis, the mirror surface shows the left part of the grass plate so that the operator can visually check the grass condition while sitting on the driver's seat. When the clutch is disengaged in an attempt to force the mirror surface to rotate, the mirror surface is rotated 90 degrees laterally from the above direction to change the direction and raise the reaper to move to the running position. The mirror on the left rear allows the operator to check the condition of the rear with this mirror.
