Abstract: A drive control system for a work vehicle is provided with a power transmission device that drives front wheels and rear wheels, a request determination unit, and a drive mode control unit. The power transmission device has a drive mode switching mechanism that performs drive mode switching between a four-wheel drive mode in which drive power is transmitted to front wheels and rear wheels and a two-wheel drive mode in which drive power is transmitted to only the rear wheels. The request determination unit determines a necessity for an increase in drive power on a contact area of the work vehicle, and outputs an increase request based on the determination result. The drive mode control unit outputs a drive mode switching request for switching to the four-wheel drive mode to the drive mode switching mechanism, in response to output of the increase request.
