A work status display means for causing a worker to recognize by display;
A reverse warning means for emitting a warning sound when the traveling body 1 moves backward, and a display restriction for stopping the operation of the work status notifying means and restricting the display operation of the work status display means when the reverse warning means is activated. With means,
The work status notification means and the reverse warning means are provided with the same alarm.
It is also used as a reporting means.

The feature of the invention according to claim 2 is that, in the invention according to claim 1, when the display operation is restricted by the display restricting means, the remaining fuel amount, the running amount, etc. It is characterized in that the operation of the display restricting means is set so that only the display of the shift position is executed and other displays are prohibited.

According to this configuration, when the vehicle is set in the reverse state, a reverse warning is issued, a panel display showing only the reverse shift state and the fuel remaining amount display is left, and other panel displays notifying the work status are turned off. . Here, even if a work status display command for another work device is issued, no work is performed during reverse travel, so there is no particular problem even if the display is not actually issued .

[Effect] Therefore, in the reverse state, the reverse warning can be accurately recognized without disturbing the unnecessary display, and the safe reverse can be performed. In the meantime, the display of the fuel remaining amount and the traveling speed change can be performed. Only important items such as the position (reverse) can be easily grasped by the display on the panel, and the problem that the operation is interrupted due to running out of fuel can be avoided beforehand.
