WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a working vehicle which can be operated by an operator at proper engine speed, running speed and PTO speed of rotation by detecting the load state of an engine under working, and letting an operator know a current engine load state.

SOLUTION: The working vehicle calculates the engine speed and an engine load; determines the propriety of the engine speed based on the calculated engine load state; instructs the change of the engine speed to the proper engine speed when it is determined that the engine speed is not proper; and instructs shift to maintain the running speed of a vehicle body and the PTO speed of rotation at a state prior to the instruction of the change of the engine speed according to the engine speed whose change has been instructed. The working vehicle is provided with a control device which causes an engine speed change instruction means and a shift instruction means to perform shift instruction when the instructed engine speed is equal to or more than the prescribed engine speed and instructs the prescribed engine speed to the engine speed change instruction means when the engine speed is less than the prescribed engine speed.
