The transmission state is a state in which the power of the PTO shaft is transmitted to the work device. The non-transmission state is a state in which the power of the PTO shaft is not transmitted to the work device. The automatic transmission state is a state in which the transmission or non-transmission of the power of the PTO shaft to the working device is automatically switched according to the lifting operation of the working device via the lifting device 10. Specifically, in the automatic transmission state, if the work device is lowered, the power of the PTO shaft is transmitted to the work device, and if the work device is raised, the power of the PTO shaft is not transmitted to the work device. And

Further, the PTO button 263 can be pressed in addition to the above rotation operation. When the PTO button 263 is pressed, the PTO button 263 can be switched from the transmission state to the non-transmission state. This makes it possible to easily stop the work performed by the work device.

The PTO button 263 is arranged behind the wiper operation button 262. As shown in FIG. 7, the PTO button 263 is provided so as to be located between the first hydraulic operation mechanism 240 and the second hydraulic operation mechanism 250 in the front-rear direction.

As shown in FIG. 9, the PTO button 263 has a straight line along the longitudinal direction of the guide hole 241 of the first hydraulic operating mechanism 240 (a straight line passing through the center of the guide hole 241 in the width direction) and a second hydraulic operating mechanism in a plan view. It is arranged at a position that does not overlap with a straight line along the longitudinal direction of the guide hole 251 of 250 (a straight line passing through the center of the guide hole 251 in the width direction). Further, the PTO button 263 is arranged at a position that does not overlap with a straight line along the longitudinal direction of the guide hole 231a of the auxiliary shift operation mechanism 230 (a straight line passing through the center of the guide hole 231a in the width direction) in a plan view. That is, the PTO button 263 is arranged so as not to be located on a straight line along the operating direction of the first hydraulic lever 242, the second hydraulic lever 252, and the auxiliary shift lever 232. Accordingly, it is possible to prevent the PTO button 263 from being erroneously operated in accordance with the operation of the various operation levers (the first hydraulic lever 242, the second hydraulic lever 252, and the auxiliary shift lever 232).

Further, the PTO button 263 has a straight line along the longitudinal direction of the guide hole 241 (guide hole 241B) of the first hydraulic operation mechanism 240 and the longitudinal direction of the guide hole 251 (guide hole 251A) of the second hydraulic operation mechanism 250 in plan view. It is located inside the front-back direction of the straight line along the direction.

The horizontal control button 265 is arranged at the rearmost position in the inner area 210C. Further, the horizontal control button 265 is arranged behind the armrest 100 and the backrest portion 16b of the seat 16.

By arranging the horizontal control button 265 as described above, the operability of the horizontal control device can be improved. That is, during operation of the horizontal control device, the driver often visually recognizes the rear (obliquely right rear) while seated on the seat 16. Therefore, by arranging the horizontal control button 265 as described above, it is possible to make it easy to operate while visually recognizing the rear side.

In the illustrated example, a space is provided between the one-touch tilling button 261 and the wiper operation button 262 in the inner area 210C, in which a space where a predetermined button can be added is provided. If necessary, a new button can be added to the above space in addition to the above-described operation switch 260.

It is arranged on the console 200. In addition, the armrest 100 can close the setting switch 130 by the cover 180.

With the above-described configuration, even when the operation switch 260 is operated from the seat 16 side over the setting switch 130, the setting switch 130 is closed by the cover portion 180 of the armrest 100, so that the setting switch 130 is closed. Contact can be prevented. On the other hand, since the operation switch 260, which is relatively frequently used, is exposed on the side console 200, the operation switch 260 is easily operated.

Further, in the side console 200, since the operation switch 260 is arranged in the inner area 210C closer to the seat 16 than in the side area 210B, the side console 200 is configured to be easily operated with respect to various devices of the tractor 1.

Further, in the inner area 210C, the operation switches 260 are arranged in a line in the front-rear direction. As a result, the operation switches 260 can be arranged in a visually appealing manner. By arranging the PTO button 263 in the middle of the front and rear of the operation switch 260, of the operation switches 260 other than the PTO button 263, the PTO button 263 is located at a position relatively easy to operate from which button is being operated. Can be placed.

Further, in the inner region 210C, the wiper operation button 262 is arranged at a position overlapping with a straight line along the longitudinal direction of the guide hole 241 (guide hole 241B) of the first hydraulic operation mechanism 240 in a plan view. Further, the illumination operation button 264 is arranged at a position overlapping the straight line along the longitudinal direction of the guide hole 251 (the guide hole 251A and the guide hole 251B) of the second hydraulic operation mechanism 250. In other words, on the straight line along the operating direction of the first hydraulic lever 242 and the second hydraulic lever 252, there is arranged one that has a comparatively small influence on the work even if it is operated by mistake.

The left side surface of the side surface portion 270 is adjacent to the right end portion of the seat base portion 12b. A boundary portion between the front surface and the left surface of the side surface portion 270 is formed into a curved surface shape that is directed diagonally left front.

The front surface of the side surface portion 270 has a curved surface shape with the front end portion as an apex in a plan view. The front surface of the side surface portion 270 is a gently inclined surface that spreads forward as it goes downward.

As shown in FIG. 12, the left surface of the side surface portion 270 is formed with two steps that spread downward to the left. Specifically, the left surface of the side surface portion 270 is provided with a step projecting leftward in the upper portion, and further provided with a step projecting further leftward in the vertical center portion.

The side surface portion 270 includes a housing portion 280, an opening portion 290, and a cover portion 293.

The accommodating portion 280 is capable of accommodating a predetermined electric device. The housing portion 280 is a space inside the side console 200 partitioned by the side surface portion 270, the operation surface portion 210, and the left side portion of the fender 9.

As shown in FIGS. 11 to 13, the housing portion 280 houses a relay box 281 and a fuse box 282. The relay box 281 houses a relay (relay). The fuse box 282 accommodates a fuse. The relay and the fuse are each connected to an electric cable wired inside the tractor 1.

The relay box 281 and the fuse box 282 are housed in the front part of the housing part 280 (in front of the left part of the fender 9). The relay box 281 and the fuse box 282 are arranged so as to be vertically adjacent to each other via a support portion 283 provided in the housing portion 280. That is, the relay box 281 and the fuse box 282 are arranged so as to be concentrated in the front portion of the housing portion 280. In the illustrated example, a three-stage relay box 281 is disposed on the lower side via a support portion 283, and a one-stage fuse box 282 is disposed above the relay box 281.

At least a part of the second opening 292 is opened in a rear side portion of the side surface portion 270 (a portion located rearward of the front end portion of the seat base portion 12b). The second opening 292 opens on the left surface of the side surface portion 270 so as to be continuous with the upper rear portion of the first opening 291.

The vertical dimension of the second opening 292 is smaller than the vertical dimension of the first opening 291. The second opening 292 is provided above the seat base portion 12b so that the rear end portion is located rearward of the front end portion of the seat base portion 12b. That is, the second opening 292 projects rearward from the upper rear portion of the first opening 291 so as to avoid the seat base portion 12b.

In other words, the opening 290 has an inverted L shape in which the rear end of the second opening 292 is located rearward of the rear end of the first opening 291. With the above-described shape, the opening size of the opening 290 can be made relatively large while avoiding interference with the seat base portion 12b.

The opening 290 overlaps with the entire relay box 281 and fuse box 282 in a front view and a side view. Specifically, the first opening 291 overlaps with the entire relay box 281 and fuse box 282 in a front view and a side view.

With the above configuration, the entire relay box 281 and fuse box 282 can be exposed through the opening 290 (first opening 291). This makes it possible to easily inspect and maintain the relay box 281 and the fuse box 282, which are electrical equipment that require relatively high maintenance such as component replacement.

Further, since the first opening 291 is provided so as to open in most of the front side portion of the side surface portion 270, it is possible to make the inspection and maintenance easier.
