It is desirable to provide a recess also on the left side of 20.

  At this time, as shown in the plan views of the vicinity of the cockpit seat 20 in FIGS. 8 and 9, the auger operation panel 40 is disposed in the left side portion and the right side portion of the cockpit seat 20 so that the front and rear directions of the auger operation panel 40 are opposite to each other. Can be placed in the orientation.

  As shown in FIG. 8, when the operator is placed on the right side of the cockpit 20, the operator operates the auger operation panel 40 while looking back at the right back, but the left side of the cockpit 20 as shown in FIG. When the auger 15 is extended directly behind the operator, switches for moving each auger are arranged so that it is convenient to stand and face backward to operate the auger operation panel 40. In this way, by unifying the turning direction of the auger 15 based on the direction operated by the operator, erroneous operation can be prevented.

  Further, when the engine cover (not shown) is opened to the side as shown in FIGS. 10 and 11 to maintain the engine below the cockpit 20, the auger operation panel 40 is integrated with the cockpit 20. Configure to open.

  The above configuration facilitates maintenance of the engine and the like. In particular, when the auger operation panel 40 is arranged on the left side of the cockpit 20, if the auger operation panel 40 is not opened integrally with the engine cover, the wiring may get in the way or the wiring may be cut. With the above configuration, such a problem can be prevented.

  8 and 12, when the auger operation panel 40 is disposed on the side portion of the cockpit 20, the auger manual lever 43 is disabled during the combine traveling, and the auger 15 is automatically extended and automatically extended. Only the storage switch 44 is enabled. This is because the auger operation panel 40 is provided in the vicinity of the cockpit 20 of the combine 1 to prevent the operator from inadvertently touching the auger manual lever 43 and operating the auger 15 by mistake. Since the automatic extension / automatic storage switch 44 is smaller than the auger manual lever 43 and there is no risk of accidental touching, only the automatic extension / automatic storage switch 44 is enabled even during the traveling of the combine. In addition, the auger operation panel 40 is further provided with an auger automatic overhang position setting dial 45, an emergency stop switch 46, a dredger discharge switch 47, and the like.

  As another embodiment of the present invention, as shown in FIG. 13, a side operation display unit 50 is provided on the outer side of the operation unit including the guide plates 38 of various levers provided on the left side of the cockpit 20. The display unit 50 uses a liquid crystal display.

Etc. are always displayed.

  Conventionally, the area of the information display section of meters using liquid crystal is small, and necessary information has been dealt with by switching the display of the liquid crystal display section. However, necessary information could not be confirmed quickly. However, in this embodiment, even if the display amount of work information increases, the operator can always confirm a plurality of pieces of information.

  Further, as shown in FIG. 14, the auger operation panel 40 is attached to the right center portion of the backrest of the cockpit 20. Further, the auger operation panel 40 can be rotated up and down on the right side of the backrest of the cockpit 20 like an armrest, and when not in use, it can be stored in the backrest side portion as shown by a one-dot chain line in FIG. It may be possible to prevent this.

  Further, as another embodiment of the present invention, as shown in FIG. 15, the front meter panel 36 is rotatably attached to a rotation fulcrum 35 a of the base of the cradle support arm 35, and the fulcrum of the cradle attachment arm 35 is rotated. The display state of the meter on the meter panel 36 can be turned with the fulcrum 35a as a fulcrum, and can be easily seen for each person whose conditions are different from those of the operator seated in the cockpit 20, such as an operator in a standing position. The rotation angle can be adjusted so that the display surface of the meter panel 36 can be directed to the position.

  Furthermore, as another embodiment of the present invention, as shown in FIG. 16, a seat 53 may be attached to the upper part of the auxiliary step 52 in the foot position of the operator who sits on the cockpit 20. Although this embodiment is a modification of the embodiment shown in FIG. 3, the main transmission lever 22, the auxiliary transmission lever 23, the mowing / threshing lever 24, etc. are also installed in the guide plate 38 on the left side of the cockpit 20 in this embodiment.

The seat 53 is configured to be rotatable about an axis C oriented in the vertical direction at a substantially central portion below the seating portion of the cockpit seat 20.

  Conventionally, since the auxiliary step 52 is fixed to the vehicle body 2 of the combine 1 together with the cockpit 20, the operator sits on the cockpit 20 while the operator is sitting on the cockpit 20 at the time of work such as discharging the rod from the auger 15 to the outside. It was difficult to work facing outward. However, by rotating the seat 53 on the auxiliary step 52 to the outside, the operator can work while checking the state of the kite discharged from the auger 15 from the outside of the combine 1 body while on the seat 53. Can be easily performed.

  By the way, although the frequency of use of switch operation is increasing recently, there are a lot of various levers and switch groups in the layout of the conventional cab 25, and the frequently used various levers are arranged at easy-to-operate positions. Therefore, the switches are often located away from the operator.

  Therefore, as an embodiment of the present invention, as shown in the perspective view of FIG. 17A and the side view of the mounting portion of the arm 22a of the main transmission lever 22 in FIG. 17B, the left side of the cockpit 20 for the combine 1 is shown.
