摘要： In a working vehicle 141, there is dissolved a risk that a black smoke is discharged, a knocking is generated and an engine stall is caused, if a lot of load is applied to a rotary tiller 24 during various works while traveling at a low speed. In the working vehicle 141 provided with an engine 70 which is mounted to a travel machine body 142, a common rail type fuel injection device 117 which injects fuel to the engine 70, and a continuously variable transmission 159 which shifts power from the engine 70, an engine driving point Q (Q1 †’ Q2) relating to a rotating speed N and a torque T of the engine 70 is changed in such a manner that the rotation speed come to a high speed side rotating speed N2 dissolving an overload, and a change gear ratio of the continuously variable transmission 159 is modified and regulates in such a manner that a vehicle speed V of the travel machine body 142 does not change in the case that the overload acts on the engine 70 of having a low speed N1 in the rotating speed N.

摘要： In a working vehicle 141, a clogging of an exhaust gas purification device 50 can be cleared without forcedly renewing the exhaust gas purification device 50 during various works while traveling at a low speed. In the working vehicle 141 provided with an engine 70 which is mounted to a travel machine body 142, a common rail type fuel injection device 117 which injects fuel to the engine 70, a continuously variable transmission 159 which shifts power from the engine 70, and the exhaust gas purification device 50 which is arranged in an exhaust system of the engine 70, in the case that an engine operating point Q relating to a rotating speed N and a torque T of the engine 70 is in a low-speed and low-torque side incapable of self-renewing the exhaust gas purification device 50, the engine operating point Q is changed to a high-speed and low-torque side capable of self-renewing the exhaust gas purification device 50, and a change gear ratio of the continuously variable transmission 159 is changed and regulated in such a manner that a vehicle speed V of the travel machine body 142 is not changed.
