Abstract
Controllability of a vehicle such as a skid steer loader is improved and the burden on an operator is reduced. When operation is conducted according to the first operation pattern, the pattern switching lever of the first switching valve is switched to the first operation pattern side and the pattern switching lever of the second switching valve is switched to the first operation pattern side. Furthermore, when operation is conducted according to the second operation pattern, the pattern switching lever of the first switching valve is switched to the second operation pattern side and the pattern switching lever of the second switching valve is switched to the second operation pattern side. Moreover, when operation is conducted according to the third operation pattern, the pattern switching lever of the first switching valve is switched to the third operation pattern side and the pattern switching lever of the second switching valve is switched to the third operation pattern side.
