Abstract
In the work vehicle, a controller is configured to control a motor displacement control part via feedback control so that the driving hydraulic pressure detected by a driving hydraulic pressure detector approaches a predetermined target driving hydraulic pressure. The controller is configured to perform low temperature motor displacement limitation control, which reduces the maximum displacement of a hydraulic motor, when the temperature of the hydraulic fluid detected by the fluid temperature detector is lower than a predetermined temperature.
