The lifting device 9 can raise and lower the attached working equipment using an actuator such as a hydraulic cylinder. Power from the engine 3 can be transmitted to the lifting device 9 via a PTO shaft (not shown).

[0022] The power of the engine 3 is changed in speed by a transmission (not shown) housed in a transmission case 5, and then can be transmitted to front wheels 6 via the front axle mechanism, and can be transmitted to rear wheels 7 via the rear axle mechanism. The front wheels 6 and rear wheels 7 are driven to rotate by the power of the engine 3, allowing the tractor 1 to travel. The power of the engine 3 can also be used to drive a working device attached to the lifting device 9.

[0023] A cabin 10 is provided behind the engine 3. The space inside the hood 4 in which the engine 3 is located is separated from the space inside the cabin 10 by a partition plate 14 (see Figure 3). The cabin 10 is mounted on the vehicle body (transmission case 5, etc.). A living space for the driver is formed inside the cabin 10. A seat 11 for the driver to sit in is located approximately in the center of the cabin 10. A steering wheel 12 for adjusting the turning angle of the front wheels 6 and a steering post 13 for supporting the steering wheel 12 are located in the front of the cabin 10.

[0024] A position detection device 15 capable of detecting the position of the body of the tractor 1 is provided above the cabin 10. The position detection device 15 is a device capable of detecting the position of the body (position information including latitude and longitude) using a satellite positioning system such as a GPS. The tractor 1 can execute control to automatically steer the body based on the position information detected by the position detection device 15. The above control includes, for example, control to automatically steer the body so that the vehicle travels straight in parallel with a predetermined set travel reference line.

[0025] The configuration of the steering post 13 will be described below.

[0026] The steering post 13 shown in Figures 2 to 4 is for supporting the steering wheel 12. The steering post 13 rotatably supports the steering wheel 12, a steering shaft (not shown) connected to the steering wheel 12, and the like using various support members.

[0030] The second display device 22 is formed to be smaller than the first display device 21. The second display device 22 is formed to be approximately trapezoidal in rear view (see FIG. 5). The left and right centers of the lower end of the second display device 22 are formed to bulge slightly downward. The second display device 22 is formed with fixing portions 22b that are fixed to the upper cover 24, which will be described later. The fixing portions 22b are formed to protrude left and right from both left and right end portions of the second display device 22, respectively.

[0031] The first display device 21 and the second display device 22 are arranged vertically in front of the steering wheel 12. The first display device 21 is supported on the body (cabin 10) of the tractor 1 by a support member 23 (see FIG. 6, etc.) described later. The second display device 22 is supported on the body of the tractor 1 by an upper cover 24 described later.

[0032] The upper cover 24 covers the upper part of the steering post 13 (the first display device 21, the second display device 22, etc.). The upper cover 24 is formed in a hollow box shape. The upper cover 24 is formed with a first opening 24a and a second opening 24b for exposing the display surface 21a of the first display device 21 and the display surface 22a of the second display device 22 toward the rear. The second opening 24b is formed to be located above the first opening 24a. The upper end surface 24c of the upper cover 24 is formed in an inclined shape that slopes downward toward the front (see FIG. 3).

[0033] The lower cover 25 covers the lower part of the steering post 13. The lower cover 25 is formed in a hollow box shape. The lower cover 25 is disposed below the upper cover 24. The upper cover 24 and the lower cover 25 are disposed so as to be in contact with each other without any gaps.

[0034] 2 and 3 covers the steering shaft and the like connected to the steering wheel 12. The shaft cover 26 is disposed so as to extend upward from the lower cover 25 toward the steering wheel 12.

[0035] Next, the configuration of the support member 23 will be described with reference to FIGS.

[0036] The support member 23 is formed by appropriately combining plate materials, and is formed with a lower fixing portion 23a, a display device fixing portion 23b, a closing portion 23c, and a cover fixing portion 23d.

[0037] The lower fixing portions 23a are portions for fixing the support member 23 to the body of the tractor 1. The lower fixing portions 23a are formed on the left and right sides of the lower portion of the support member 23. The lower fixing portions 23a are fixed to brackets 14a formed on the partition plate 14 using appropriate fixing devices (bolts, etc.).

[0038] The display device fixing portions 23b are portions for fixing the first display device 21. The display device fixing portions 23b are formed at four locations in total: on the left and right sides of the lower part of the support member 23 and on the left and right sides of the upper part.

[0039] Closing portion 23c is a plate-shaped portion that closes the opening of upper cover 24 from the front. Closing portion 23c is formed on the upper portion of support member 23. Closing portion 23c is formed in a shape that corresponds to the shape of upper cover 24 (in this embodiment, a generally trapezoidal shape when viewed from the front).

[0040] The cover fixing portion 23d is a portion for fixing the upper cover 24. The cover fixing portion 23d is formed on the left and right sides of the upper portion of the support member 23 (the closing portion 23c), respectively.

[0041] Next, a method for assembling the first display device 21, the second display device 22, and the upper cover 24 will be described with reference to FIGS.

[0042] First, the support member 23 is fixed to the bracket 14a of the partition plate 14. Specifically, the lower fixing portion 23a of the support member 23 is fixed to the bracket 14a using a bolt or the like (see FIG. 6).

[0043] 6 and 8, the first display device 21 is fixed to the support member 23. Specifically, the fixing portion 21b of the first display device 21 is fixed to the display device fixing portion 23b of the support member 23 using a bolt or the like.

[0044] On the other hand, the second display device 22 is fixed to the upper cover 24. Specifically, the positions of the second display device 22 and the upper cover 24 are aligned so that the display surface 22a of the second display device 22 is exposed rearward from the second opening 24b of the upper cover 24. In this state, the fixing portion 22b of the second display device 22 is fixed to the inner surface of the upper cover 24 using a bolt or the like.

[0045] Next, as shown in Fig. 8, the upper cover 24 to which the second display device 22 is fixed is attached so as to cover the first display device 21. Specifically, the position of the upper cover 24 relative to the first display device 21 is adjusted so that the display surface 21a of the first display device 21 is exposed rearward from the first opening 24a of the upper cover 24. In this state, the upper cover 24 is fixed to the cover fixing portion 23d of the support member 23. Note that the upper cover 24 may be fixed not only to the cover fixing portion 23d but also to the lower cover 25 or another appropriate support member.

[0046] In this way, in this embodiment, the multiple display devices (first display device 21 and second display device 22) are not covered with individual covers, but are covered by the integrally molded upper cover 24. This prevents the formation of joints (gaps) between the individual covers, improving the aesthetic appearance of the tractor 1.

[0047] In this embodiment, the first display device 21 is fixed to the support member 23, and the second display device 22 is fixed to the upper cover 24. By adjusting the position of the upper cover 24 to which the second display device 22 is fixed relative to the first display device 21, the first display device 21 and the second display device 22 are aligned with the upper cover 24.

[0048] By configuring in this manner, even when multiple display devices (first display device 21 and second display device 22) are installed, the position of each display device can be aligned with the upper cover 24, thereby preventing misalignment between the multiple display devices and the upper cover 24, and ultimately improving the aesthetic appearance of the tractor 1.

[0049] Next, the positional relationship between the first display device 21, the second display device 22, and the support member 23 that are assembled to the tractor 1 will be described with reference to FIGS.

[0050] When the first display device 21, the second display device 22, and the support member 23 are assembled to the tractor 1, the second display device 22 is disposed above the first display device 21. The first display device 21 and the second display device 22 are disposed so as not to overlap each other in a rear view (see FIG. 5). This allows multiple display devices to be assembled to the tractor 1 easily.

[0051] The second display device 22 is disposed at a height such that at least a portion of the second display device 22 overlaps with the support member 23 in the height direction. The second display device 22 is also disposed so as to overlap with the support member 23 in a rear view (see FIG. 5).

[0052] 9, the first display device 21 is arranged so that a height position A of the upper end of the first display device 21 (fixed portion 21b) is higher than a height position B of the lower end of the second display device 22. That is, the second display device 22 is arranged at a height where at least a portion of the second display device 22 overlaps with the first display device 21 in the height direction. By arranging them in this manner, the first display device 21 and the second display device 22 can be arranged in positions close to each other, and therefore, multiple display devices can be arranged compactly.

[0053] As described above, the tractor 1 according to this embodiment has the following features: a plurality of display devices (first display device 21 and second display device 22) each having a display area (display surface 21a and display surface 22a) capable of displaying information relating to the tractor 1 (work vehicle); an upper cover 24 (cover member) that is integrally molded and covers the plurality of display devices while leaving the display area exposed; It is equipped with the following.

[0054] This configuration can improve the aesthetic appearance of the tractor 1. That is, instead of covering the multiple display devices with individual cover members, the aesthetic appearance can be improved by covering them with an integrally molded seamless upper cover 24. Furthermore, by using the integrally molded upper cover 24, it becomes easier to make the overall size more compact than when individual cover members are used.

[0055] Moreover, the plurality of display devices include a first display device 21 fixed to the body of the tractor 1 via a support member 23; a second display device 22 fixed to the upper cover 24 and fixed to the body of the tractor 1 via the upper cover 24; It includes:

[0056] This configuration can improve the aesthetic appearance of the tractor 1. That is, by assembling the upper cover 24 to which the second display device 22 is fixed in alignment with the first display device 21, it is possible to accurately align the positions of the multiple display devices (the first display device 21 and the second display device 22) with the upper cover 24, thereby improving the aesthetic appearance of the tractor 1.

[0057] In addition, the second display device 22 is It is disposed above the first display device 21.
