WORK VEHICLE HAVING A WORK IMPLEMENT
A work vehicle is equipped with an engine, a hydraulic pump, a work implement, a work implement operating member, a work implement control valve, a capacity control device, a travel device, an accelerator operating member, and a control unit. The hydraulic pump is driven by the engine. The work implement is driven by hydraulic fluid discharged from the hydraulic pump. The work implement control valve controls the hydraulic pressure supplied to the work implement. The capacity control device controls a differential pressure between a discharge pressure of the hydraulic pump and an outlet hydraulic pressure of the work implement control valve. The travel device is driven by the engine. The accelerator operating member changes the engine rotation speed. The control unit causes the speed of the work implement to increase by causing the engine rotation speed to increase when an operation amount of the work implement operating member is increased.
