The battery-powered lawn mower LM001J has three modes: "Normal" is suitable for tasks that require power, such as cutting overgrown or dense grass, or tasks that require air volume, like cleaning up fallen leaves. The speed is 2,800 rpm. In "SoftNoLoad," the speed is automatically adjusted based on the machine's load. Therefore, the machine can operate energy-efficiently depending on the density of the grass and the speed at which the user pushes it. The speed varies between 2,300 and 2,800 rpm. "Noise Reduced" is optimal for use in noise-sensitive environments, such as residential areas. The speed is consistently set at 2,300 rpm. At a lower speed, a reduced airflow may result in not fully utilizing the entire volume of the grass collection bag.
