When any of the command buttons 24 to 28 is pressed, the control device 3 executes a command corresponding to the icon. The icons and commands assigned to the command buttons 24 to 28 are different for each screen, and the icons and commands necessary for each screen are assigned.

  As commands, a command for instructing switching to the first home screen S3 (icon is “HOME”), a command for instructing switching to a shortcut screen (screen arbitrarily set by the operator) (icon is “free 1”) “Free 2”), a command for instructing determination of one element (the icon is “decision”), a command for instructing switching to the previous screen (icon is “return”), tab, like the enter button 23 There is a command (the icon is an arrow indicating the direction) for instructing the direction of scrolling or the direction of traversing the highlight display.

  In addition, you may provide a touch panel in the liquid crystal panel 21 as an operation part. In this case, the encoder dial 22, the enter button 23, and the command buttons 24-28 can be omitted as appropriate.

  By the way, the storage unit 31 stores a memo image (see FIG. 16) in which the work machine mounting conditions can be input. The control device 3 of the tractor 1 reads the memo image from the storage unit 31 and reads the liquid crystal panel 21. Control to display on the screen. The memo image is stored for each work machine. In the work machine selection image (see FIG. 15) in which a plurality of work machines are recorded, the operator selects and determines a desired work machine, so that the work machine is selected. It is possible to read out and display a memo image corresponding to.

  Further, the control device 3 performs control so as to accept an input (see FIG. 17) of a work implement mounting condition through the operation unit (encoder dial 22, enter button 23, command buttons 24-28). In addition, the control device 3 controls the storage unit 31 to store the memo image to which the work machine mounting condition is input. In addition, when storing the memo image in which the work machine mounting condition is input, the input mounting condition information may be stored as information integrated with the memo image, or the input mounting condition information may be stored in the memo image. The image may be stored in association with the image and superimposed when the memo image is displayed.

  The memo image may be any image that allows at least the operator to memo (input) the work machine mounting conditions. The input method may be a method of inputting an arbitrary character in the input field, or a method of selecting from the mounting conditions described in the input field so as to be selectable in advance.

  In addition, each item of the work machine mounting conditions may be written in advance in the memo image. If the work machine is a rotary, the item can be composed of an item name such as the length of the top link and an input field corresponding to the item name. As a result, the operator only needs to fill in the input field, so that the operator can easily make a note and can prevent the user from forgetting to write down any of the mounting condition items.

  In addition, a drawing of a portion (link mechanism) to which the work machine is attached may be written in advance in the memo image. This makes it easier for the operator to understand and improves the convenience of the memo image. Furthermore, if each item of the above mounting conditions is arranged at a position corresponding to each part in this figure, the operator can understand more easily. The memo image may be provided with other input fields such as a comment field in which an operator's comment can be input.

  In this way, by using the memo image in the tractor 1, the operator can store the work equipment mounting condition in the tractor 1 instead of recording it in the notebook. Therefore, there is no problem that it is complicated to find a recorded part from the notebook or the recorded notebook is lost, and it is possible to immediately confirm the mounting condition of the work machine with a memo image when necessary. As a result, even a work machine that is used once a year can be mounted in a short time, and work efficiency is improved.
