摘要： A controller controls a first drive source and a second drive source based on a moving speed of a motor grader measured by a speed sensor and a turning angular velocity of the motor grader measured by an IMU, to thereby independently control a rotation speed of each of a right front wheel and a left front wheel.

摘要： A working vehicle includes an engine, an air blowing device, an exhaust gas post-processing device, and a guide device. The air blowing device is disposed in front of the engine. The exhaust gas post-processing device processes exhaust gas from the engine, and is disposed above the engine. The guide device lifts and guides at least portion of the air from the air blowing device to an upper side where the exhaust gas post-processing device is provided.

摘要： A work vehicle includes an engine, a selective catalytic reduction apparatus, a fuel tank, and a reducing agent tank. The selective catalytic reduction apparatus treats exhaust from the engine. The fuel tank includes a fuel tank body retaining fuel and a fuel supply port which supplies fuel to the fuel tank body. The reducing agent tank includes a reducing agent tank body retaining a reducing agent used in the selective catalytic reduction apparatus and a reducing agent supply port which supplies the reducing agent to the reducing agent tank body. The fuel supply port protrudes from the fuel tank body toward a first direction left or right with respect to a center axis line in the front and back direction of the vehicle. The reducing agent supply port protrudes from the reducing agent tank body toward a second direction opposite to the first direction.
