Claim:
1. A work vehicle provided with an implement, the work vehicle comprising: an engine; a variable displacement travel hydraulic pump configured to be driven by the engine; a hydraulic motor forming a closed circuit with the travel hydraulic pump and configured to be driven by hydraulic fluid discharged from the travel hydraulic pump; a driven wheel configured to be driven by the hydraulic motor to allow the work vehicle to travel; a selector switch configured to detect an operating state of a traveling direction switching device configured to switch a traveling of the work vehicle between forward and backward; and a control device configured to set, in a case in which the selector switch detects a reversal operation of the traveling direction switching device to reverse a traveling direction of the work vehicle when the work vehicle travels, a relationship between a vehicle speed of the work vehicle and an upper limit of a rotational speed of the engine in a manner such that the upper limit increases as an absolute value of the vehicle speed approaches zero, the control device being configured to obtain an upper limit of a rotational speed of the engine from the set relationship and a vehicle speed of the work vehicle.
