Abstract: To improve working efficiency in an eco mode when a power mode and the eco mode have been set in a wheel loader, the wheel loader is provided with a controller having an eco mode characteristic line, a power mode characteristic line, and a lifting operation characteristic line having a matching point C located between a matching point A between a working device operating engine torque characteristic line and the eco mode characteristic line and a matching point B between the working device operating engine torque characteristic line and the power mode characteristic line. The controller includes a control portion, which controls a HST pump in accordance with the lifting operation characteristic line when lifting operation of a lift arm is detected while the eco mode has been selected by a work mode selecting portion.

Abstract: An exhaust system of a work machine is equipped with a first exhaust system, a second exhaust system, and a third exhaust system. The first exhaust system and the third exhaust system are arranged to be in parallel with respective one ends directed in the same direction. In a plan view, the second exhaust system is arranged with the other end side directed in the same direction as the one end sides of the first exhaust system and the third exhaust system to be in parallel with the first exhaust system and the third exhaust system between the first exhaust system and the third exhaust system and, in a side view, is arranged above the first exhaust system and the third exhaust system.
