Abstract: A wheel loader includes a vehicle frame, an engine, a supporting mechanism, a diesel articulate filtering device, and a connecting pipe. The engine is mounted on the vehicle frame, and the supporting mechanism is fixed to the vehicle frame. The diesel particulate filtering device is mounted on the supporting mechanism above the engine and has an exhaust gas inlet facing the rear. An exhaust upstream side end part of the connecting pipe is coupled to an exhaust part of the engine, and an exhaust downstream side end part of the connecting pipe is connected to an exhaust gas inlet of the diesel particulate filtering device from the rear. The connecting pipe includes an extending part that is disposed below the diesel particulate filtering device and extends rearward of the diesel particulate filtering device from the exhaust upstream side end part, and a flexible pipe part provided in the extending part.

Abstract: A work vehicle allowing a simplified operation to open and close a shutter in a simple configuration is provided. The shutter can be disposed alternatively at a first position at which the shutter protrudes forward from a lower end of a blade or at a second position at which the shutter is farther away from the lower end than at the first position. The controller is configured to receive an input of an operation instruction from an input operation unit for moving the shutter from the second position to the first position, to cause the shutter to move from the second position to the first position. After a lapse of a prescribed time period since the shutter is moved to the first position, the controller causes the shutter to move from the first position to the second position.

Abstract: A wheel loader includes a cab, steps provided beside the cab, an engine disposed to the rear of the cab, a vehicle body cover covering the engine, and an air cleaner. The air cleaner has a filter exchangeable by being pulled out horizontally. The air cleaner is connected to the engine via an intake pipe. The air cleaner is disposed to an outside of the vehicle body cover and to the rear of the cab, and is disposed in a slanted manner so that a side from which the filter is pulled out is further away from the cab than an opposite side.

Abstract: A work vehicle includes a blade, a shutter, a notification unit, and a controller. The blade includes a lower end. The shutter is attached to the blade. The shutter can be alternatively disposed at a first position at which the shutter protrudes forward from the lower end of the blade or at a second position at which the shutter is farther away from the lower end than at the first position. The notification unit is configured to notify surroundings of the work vehicle about information of the work vehicle. The controller is configured to change information notified by the notification unit in accordance with an arrangement of the shutter at one of the first position and the second position.

Abstract: A wheel loader includes a vehicle frame, an engine, an operating fluid tank, a stand, a rear support frame, and a base member. The engine is mounted on the vehicle frame. The operating fluid tank is disposed in front of the engine. The stand is fixed to the vehicle frame and supports the operating fluid tank. The rear support frame is disposed facing the stand with the engine interposed there-between and fixed to the vehicle frame. The base member is disposed above the engine and has one end fixed to an upper part of the stand and the other end fixed to an upper part of the rear support frame. A diesel particular filter, a nitrogen oxide reduction catalytic converter, and a connecting pipe are all mounted on the base member with the connecting pipe connecting the diesel particulate filtering device and the nitrogen oxide reduction catalytic converter.
