Abstract: The display system of the excavating machine has a work machine condition detection unit which detects information related to a current position of an excavating machine and a processing unit. This processing unit calculates an icon display of the bucket and the positions of the excavation edge portions viewed from a top of the excavating machine based on the information related to the current position of the excavating machine, the information related to the posture of the main body, the information about the positions of the excavation edge portions and the outer shape information about the bucket, and displays on a screen of a display device the target surface, the icon display position of the bucket, and an image which indicates the positions of the excavation edge portions.

Abstract: A work vehicle having a plurality of working modes allowing working in accordance with a load state includes an engine, an exhaust gas purification apparatus, a reducing agent tank, a state determination portion, and an engine control unit. The exhaust gas purification apparatus purifies a nitrogen oxide in an exhaust gas. The reducing agent tank stores a reducing agent. The state determination portion determines a state of the reducing agent. The engine control unit controls output of the engine with the use of a restricted-operation engine output torque curve in which horsepower output from the engine is lower than horsepower output from the engine at the time when each of the plurality of working modes is selected, when a state of the reducing agent is equal to or lower than a reference value.
