• a vehicle body provided with a plurality of wheels;
• an engine mounted on the vehicle body;
• a torque converter for amplifying a torque transmitted from the engine;
• an accelerator pedal for adjusting a rotational speed of the engine;
• a brake pedal for adjusting a braking force applied to the plurality of wheels;

• a loading hydraulic pump driven by the engine and supplying a hydraulic oil to the hydraulic cylinder;
• and
• a controller configured to control the engine,
• wherein the controller is configured to:
• limit an upper limit rotational speed of the engine based on a step-on amount of the accelerator pedal, a step-on amount of the brake pedal, a torque converter speed ratio that is a ratio of a rotational speed of the torque converter, a discharge pressure of the loading hydraulic pump, and a stroke amount of the hydraulic cylinder.
