PROBLEM TO BE SOLVED: To provide a work vehicle capable of efficiently reducing wearing of wheels by changing conditions of switching from a two-wheel driving state to a four-wheel driving state according to a travel state.SOLUTION: A work vehicle which switches between two-wheel driving and four-wheel driving comprises rotation sensors 48, 49, and a control part 50 which performs switching between the two-wheel driving and four-wheel driving according to detection results of the rotation sensors 48, 49. The control part 50 performs automatic switching control for switching to the four-wheel driving when the rotation sensors 48, 49 detect driving-side wheels 2 rotating faster than non-driving-side wheels 1 over a predetermined reference value. Further, the control part 50 makes hard the switching from the two-wheel driving to the four-wheel driving by changing the reference value to a lower-speed side when the rotation sensors detect the rotating speed of the driving-side wheels 2 being different from the rotating speed of the non-driving-side wheels 1 as predetermined.SELECTED DRAWING: Figure 9 |
