The hydraulic oil tank is disposed to the rear of the operator cab and stores hydraulic oil. The engine is disposed to the rear of the hydraulic oil tank. The engine cover is a member that covers the engine. A rear face of the hydraulic oil tank and a front face of the engine cover are the same size in a widthwise direction. A rear end of an upper face of the hydraulic oil tank is positioned at the same height as a front end of the upper face of the engine cover. The upper face and side faces of the hydraulic oil tank are exposed to outside.
