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 vehicle body 2 equipped with a travelling device 8 that travels in a farm field, a handle 32 for performing a steering operation of the vehicle body 2, a seedling planting part 50 disposed in the rear part of the vehicle body 2 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 the handle 32 and maintaining the vehicle body 2 in the straight travelling direction, and a rear wheel rotation sensor 23 for detecting a vehicle speed 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. The receiving antenna 121 decreases an information acquisition interval for the position information when the vehicle speed detected by the rear wheel rotation sensor 23 is a predetermined speed or higher, and lengthens the information acquisition interval for the position information when the vehicle speed is lower than the predetermined speed.SELECTED DRAWING: Figure 7
