PROBLEM TO BE SOLVED: To provide a work vehicle capable of improving fuel consumption since there is no need of providing two kinds of output curves of an engine.SOLUTION: A tractor 1 comprises: an engine 4; a mode changeover switch 120 for switching to any one of a standard output mode of the engine 4, and a low consumption output mode for reducing the fuel consumption compared to the standard output mode; and an engine control system 140 that uses a characteristic curve obtained by peak-cutting a prescribed amount of an upward convex characteristic curve of torque with respect to the engine speed of the engine 4 in the standard output mode when the mode changeover switch 120 is switched to the low fuel consumption output mode.SELECTED DRAWING: Figure 5 |
