Abstract:
A second frame is turnably connected to a first frame. A steering cylinder is connected to the second frame and the first frame. The steering cylinder turns the second frame in relation to the first frame. A hydraulic pump supplies operation oil to the steering cylinder. An engine drives the hydraulic pump. A steering operation member can be operated by an operator. A steering operation sensor outputs a steering command signal corresponding to the operation of the steering operation member. A controller controls the speed of an engine in response to the steering command signal, thereby controlling the flow rate of the operation oil supplied to the steering cylinder from the hydraulic pump.
