摘要： A technique that can suitably restrict a rotation rate of a motor of an excavator is provided. An excavator according to an embodiment of the present disclosure includes an engine, an engine rotation rate adjusting dial that receives an input regarding changing of the rotation rate of the engine, and an engine control part that restricts the rotation rate of the engine. When the rotation rate of the engine is restricted to lower than or equal to a predetermined upper limit by the engine control part, the rotation rate of the engine is maintained to lower than or equal to the predetermined upper limit even when the engine rotation rate adjusting dial receives an input that makes the rotation rate of the engine higher than the predetermined upper limit.
