WORK VEHICLE AND WORK VEHICLE CONTROL METHOD

An objective of the present invention is to provide a work vehicle and a work vehicle control method that can improve fuel consumption and suppress any decrease in ease of operation. In the work vehicle, the controller compares a predetermined threshold with the ratio between a lift force for raising the work implement and a traction force of the vehicle. The controller executes traction force reduction control for reducing the traction force in the case that an increase in the lift force is required.
