Abstract: In a work vehicle provided with: a working device including an arm and a bucket; a vehicle speed detection device that detects a vehicle speed; a travel drive device that outputs a travel driving force increasing in response to a decrease in the vehicle speed at a time of excavation; and a control device that controls the travel driving force by the travel drive device, the control device is characterized by including a limit control section that limits the travel driving force during a specified time which passes from when the vehicle speed detected by the vehicle speed detection device becomes a predetermined first vehicle speed threshold value or less and the work vehicle plunges into an object to be excavated until an operation of the working device is started.
