It is provided in the front part of.

Further, a traveling speed detecting device 9 for detecting the traveling speed of the tractor 1 is provided on the axle of the rear wheel 3 of the tractor 1, and the measurement value measured by this traveling speed detecting device 9 is sent to the arithmetic device 8. electrically connected to input.

Furthermore, a display device 11 is provided on the front side of the arithmetic device 8, that is, in a front part at a position where the operator 10 seated in the driver's seat 4 can easily see the display device 11, which displays the current running state using an output signal inputted from the arithmetic device 8. It is being This display device 10 includes a lighting display means 12 and a lighting display means 1 for clearly indicating a predetermined range.
2, and a warning means 13 such as a buzzer that warns of danger.

With this configuration, when the tractor 1 runs on a slope, the horizontal inclination angle of the tractor 1 is detected by the first detection mechanism 6, and the longitudinal inclination angle of the tractor 1 is detected by the first detection mechanism 6. 2 detection mechanisms 7, and the respective detected measurement values are outputted to the arithmetic unit 8. That is, the first and second detection mechanisms 6, 7
For example, by setting the values from the horizontal safety state of the tractor 1 to the overturning inclination angle to 0, 1, 2, ...10, the inclination angles of the tractor 1 in the front, rear, left, and right directions can be measured numerically. At the same time, this is converted into an electrical signal and output to the arithmetic unit 8.

Further, the traveling speed of the tractor 1 is detected by a traveling speed detecting device 9, and this detected measurement value is outputted to an arithmetic device 8. In other words, the running speed detection device 9 can detect the speed from stop to maximum speed as 0, for example.
By setting numerical values to 1, 2, .

The calculation device 8 inputs the output signals from the first and second detection mechanisms 6 and 7 and the output signal from the travel speed detection device 9, calculates the inclination angle and travel speed of the tractor 1, and calculates the current It is determined whether the driving state is safe driving, caution driving, or dangerous driving, and the result is output to the display device 11. That is, for example, by pre-memorizing and setting a safe driving range, a caution driving range, and a dangerous driving range in the calculation device 8, it can calculate input signals and display signals that correspond to any of the set values. Output to device 11.
When the signal inputted in the display device 11 indicates a caution-required driving condition, the lighting display means 12 lights up a yellow light, for example, and when the signal inputted in the display device 11 indicates a dangerous driving condition, the warning means 13 lights up a red light, for example. In addition to turning on the light, it also activates the alarm buzzer to issue an alarm. This allows operator 1
0 allows appropriate operations such as reducing the traveling speed to be taken, and also ensures safety.

〔Effect of the invention〕

According to the present invention, the inclination angle detection mechanism includes the first detection mechanism that detects the inclination angle in the left-right direction and the second detection mechanism that detects the inclination angle in the front-rear direction when the main body of the work machine is running.
