The display device 50B displays the operation display portion 83 on the attitude setting screen M5. The operation display section 83 is provided corresponding to the setting input section 82 and changes the display of the operation mode of the posture changing device 25 based on the state of the tractor 1 . The operation display unit 83 changes the display based on the operation mode calculated by the calculation device. In this embodiment, the arithmetic device is shared with the control device 40 . Note that the arithmetic device and the control device 40 may be separate.

In the following, it is assumed that the control device 40 is also used as an arithmetic device, and the calculation of the operation mode and the display of the operation mode will be described.

The tilt detection device 41k is provided in the body 3 and detects the tilt of the body 3 with respect to the horizontal direction. The control device 40 (computing device) computes the operation mode of the posture changing device 25 when the posture changing device 25 is operated in the state of the tilt detected by the tilt detecting device 41k. That is, the control device 40 (arithmetic device) determines whether the change cylinder 25a extends or contracts when the tilt of the working device 2 is changed in a predetermined direction in a state of the tilt detected by the tilt detection device 41k. This direction is obtained as an operation mode.

As shown in FIG. 13A, when the right portion of the tractor 1 is lower than the left portion of the tractor 1, the right portion of the working device 2 is also lower than the left portion.

As shown in FIG. 13B, when the tilt detection device 41k detects that the left portion of the tractor 1 (working device 2) is downward (downward to the left) and the horizontal mode is set, the control device 40 (arithmetic device ) determines the mode of operation in the direction of extension of the change cylinder 25a.

Therefore, the control device 40 causes the operation display section 83 on the reduction input section 82b side to display "stretch" indicating that the change cylinder 25a is extended, that is, "stretch" indicating the extension direction. In addition, the control device 40 causes the operation display section 83 on the side of the increase input section 82a corresponding to the right side of the tractor 1 (working device 2) to display "retraction", which is opposite to "extension" of the change cylinder 25a. .

Based on the operating state of the tractor 1 , the control device 40 determines the target display device, which is the display device 50 that can be operated by the operation tool 57 , from among the plurality of display devices 50 . ) to the target display device, the operation tool 57 is operated on the target display device. Specifically, as shown in FIG. 23, first, the control device 40 acquires either the detection information detected by the detection device 41 or the operation information of the operation member 42 (S1). The control device 40 grasps the operating state of the tractor 1 based on either the acquired detection information or operation information (S2). When the control device 40 grasps the operation state of the tractor 1, the control device 40 determines the display device with the highest operation priority among the plurality of display devices 50 as the target display device based on the operation state (S3). After determining the target display device, the control device 40 acquires an operation signal (operation information) of the operation tool 57 , and outputs the operation information to the target display device. A target display device, which is a predetermined display device, is operated (S4). Note that when the control device 40 changes the target display device to which the operation is given priority due to a change in the operation state of the tractor 1 during or after the operation by the operation tool 57, the control device 40 changes the operation tool for the target display device before the change. The operation of the operation tool 57 is stopped, and the operation of the operation tool 57 for the target display device after the change is started (S5).

FIG. 24 is a diagram showing a flow of determining a predetermined display device (target display device) from among the plurality of display devices 50 by the control device 40 and executing the operation of the operation tool 57 .
As shown in FIG. 24, when the ignition switch 42b is turned on and the operating state of the tractor 1 shifts from stopping driving to starting driving (S10), the control device 50 causes the display device (authentication display device) 50C to The target display device to which the operation is given priority is determined (S11). Further, the control device 40 sets the operation tool 57 as an input device for inputting authentication information (S12), and shifts to authentication information input processing (S13).

In the input process, the control device 40 outputs a command for inputting authentication information to the authentication display device 50C, and the authentication display device 50C displays authentication information such as a personal identification number that can be entered (S13-1). Further, when the control device 40 receives a rotation operation by the operation tool 57, it commands the authentication display device 50C to change the input digit for inputting the authentication information (S13-2). After determining the input digit, when the control device 40 accepts the rotation operation by the operation tool 57, the control device 40 commands the authentication display device 50C to change the number to be input to the input digit (S13-3). S13-2 and S13-3 are repeated, and when the completion of the input of the authentication information is accepted, the control device 40 displays the authentication information (the authentication information displayed on the authentication display device 50C) input by the operation tool 57 (input device). is stored as input authentication information (S13-4).

Fuel efficiency priority indicates that priority is given to control that maintains fuel efficiency. A third scale portion 163a of the third axis display portion 163 indicates a value giving priority to maintaining fuel consumption as a third priority value. Maintaining less control. For example, when the fuel consumption is set at a predetermined number of revolutions, the control device 40 changes the intensity of maintaining the actual fuel consumption at the set fuel consumption according to the third priority value.

For example, when the first priority value of PTO priority is higher than the other second priority value and third priority value, the control device 40 adjusts the motor rotation speed so that the PTO rotation speed becomes a predetermined rotation speed. is maintained, or the PTO rotation speed is held at a predetermined rotation speed by a combination of the prime mover rotation speed and the gear position of the PTO transmission section 5e3. For example, when the second priority value of vehicle speed priority is higher than the other first priority value and third priority value, the control device 40 controls the rotation speed of the front axle 21F or the rear axle 21R to correspond to the predetermined vehicle speed. The gear stage (transmission level) of the main transmission section 5c, the gear stage (transmission level) of the sub-transmission section 5d, the motor rotation speed, etc. are changed so as to match the rotation speed. A change in the gear stage (speed change level) of the main transmission portion 5c includes a change in the swash plate angle of the swash plate 12 of the hydraulic pump 5c1 and a change in the rotation speed output from the hydraulic motor 5c2 to the planetary gear mechanism 5c3 (the hydraulic motor 5c2 itself change in the number of revolutions, change in the number of revolutions in the input path from the hydraulic motor 5c2 to the planetary gear mechanism 5c3), change in the flow rate of the hydraulic oil supplied to the hydraulic pump 5c1 (open the control valve of the hydraulic circuit of the hydraulic pump 5c1). degree change), etc.

For example, when the third priority value for fuel efficiency is higher than the other second priority value and third priority value, the control device 40 controls the fuel consumption of the prime mover 4 to be equal to or less than a predetermined value. The shift stage (shift level) of the main transmission section 5c, the shift stage (shift level) of the sub-transmission section 5d, the engine speed, etc. are changed.
