PROBLEM TO BE SOLVED: To provide a work vehicle capable of causing a vehicle body to travel in a straight line with a high degree of precision, and improving working accuracy.SOLUTION: A work vehicle includes a seedling planting part 50 disposed in the rear part of a vehicle body 2 that travels in a farm field for performing work in a farm field, a receiving antenna 121 disposed in the vehicle body 2 for acquiring position information at a predetermined interval, a gyro sensor 115 for detecting a change in a travelling direction of the vehicle body 2, an automatic steering device 110 for operating a handle 32 and maintaining the vehicle body 2 in the straight travelling direction, and an inclination sensor 116 for detecting a longitudinal inclination of the vehicle body 2. The automatic steering device 110 is operated based on detection values of the receiving antenna 121 and the gyro sensor 115, and performs a correction so as to lengthen the position information interval before and after the detection of an inclination in an elevation direction when the inclination sensor 116 detects the inclination in an elevation direction of the machine while it performs a correction so as to decrease the position information interval before and after the detection of the inclination in a depression angle direction when the inclination sensor 116 detects the inclination in a depression angle direction of the machine.SELECTED DRAWING: Figure 7 |
