A lifting operation lever 9 and a lifting operation switch 10 are provided at the front,
Behind it (center in the front-rear direction), set the plowing depth.
However, further behind it, a plurality of operating tools 12 are arranged in a concentrated manner so as to be substantially linearly arranged in the front-rear direction in plan view. In this case, the rear part of the side panel 8 is entirely stepped low. In other words, the lower rear portion 8c is set in a space for disposing the plurality of operating tools 12. Further, the front portion of the side panel 8 is steppedly lowered with the outer side in the left-right direction remaining as a rib-shaped portion 8b, and the lower front portion 8d serves as a space for disposing the elevating operation lever 9. Then, between the low front and rear portions 8d and 8c, the rib-shaped portion 8b continues to become a convex portion 8a, and on the upper surface of the convex portion 8a, the plowing depth setting volume 11 is shown in FIG. As described above, it is arranged to be higher than the other operation tools 12 in side view. The lifting operation switch 10 is provided so as to protrude toward the front part 8d on an inclined surface between the convex part 8a and the low front part 8d. Further, the knob portion of the cultivation depth setting volume 11, which is more frequently operated, is formed larger than the other operation tools 12, thereby clearly distinguishing the operation tool 12 from the other operation tools 12.

に伴う作業精度の低下も防止できる。As described above, in the embodiment in which the present invention is implemented, on the side panel 8 provided outside the driver's seat 6 in the left-right direction, the lifting operation lever 9, the working depth setting volume 11 and the plurality of operation tools 12 are provided. However, since the cultivation depth setting volume 11 is disposed in a substantially central portion in the front-rear direction of the side panel 8 without any operation tool disposed in the left-right direction, it is concentrated at the rear portion of the side panel 8. When the operator operates the cultivation depth setting volume 11 with high operation frequency, the operator may erroneously operate the other operation tools 12 with low operation frequency, as being differentiated from the other operation tools 12 to be arranged. Failure can be prevented. As a result, it is possible to improve the operability or to prevent a decrease in work accuracy due to an erroneous operation.
そのうえこのものでは、耕深設定ボリユーム11を操作

放させる面倒も無い。Moreover, since the cultivation depth setting volume 11 is provided in an exposed state without being covered by the operation tool cover 13 like the other operation tools 12, it can be further differentiated from the other operation tools 12. There is no trouble to open the operation tool cover 13 every time the operation is performed.
さらに、耕深設定ボリユーム11の摘み部を他の操作具
類12のものよりも大きく形成しているので、尚一層の差
別化を計ることができると共に、後方の作業状態を確認
しながらでも手を直ぐに摘み部に置くことができて操作
性も向上できる。Furthermore, since the knob of the tillage setting volume 11 is formed larger than that of the other operation tools 12, further differentiation can be achieved, and the hand can be checked while checking the working state at the rear. Can be immediately placed on the knob to improve operability.
また、操作具類12を覆蓋する操作具カバー13は、90°

Therefore, while the plurality of operating tools including the tillage depth setting device are arranged on the side panel, the tillage depth setting device is moved up and down. There is no arrangement of other operation tools on the convex portion of the middle part of the side panel sandwiched between the front part where the operation lever is disposed and the rear part where other operation tools are disposed, and The other operating tools at the rear are covered with the operating tool cover, and only the tillage setting device is exposed, so that it can be differentiated from other operating tools. There is no mistake in operating other operating tools.
そして、耕深設定器を操作する場合には、閉鎖状態で
