PROBLEM TO BE SOLVED: To solve a problem wherein conventional working vehicles are limited to vehicle height adjustments utilizing single cylinders for reaping members and can not adjust lateral inclinations. SOLUTION: In this working vehicle, a travel apparatus 4 is disposed under a machine frame 1. In the travel apparatus 4, right and left travel frames 6 are disposed in a state capable of being lifted or lowered from the machine frame 1 through link mechanisms 13. One of the right and left link mechanisms 13 lifts or lowers the travel frame 6 with a single cylinder 15, and the other is connected to one of the link mechanisms 13 through a rotation shaft 25. Thereby, the right and left travel frames 6 are lifted or lowered with the single cylinder 15. A switching mechanism 16 for switching the connection of the right and left link mechanisms 13 is disposed in the intermediate portion of the rotation shaft 25. A holding mechanism 35 for holding the vehicle height on the other travel frame 6B side is disposed on the other travel frame 6B side lifted or lowered through the switching mechanism 16 among the right and left travel frames 6.
