  "textContent": "A manned mower includes a vehicle frame and a support portion used for supporting a user; a traveling wheel set supporting the vehicle frame; a mowing element driven by a mowing electric motor; and a controller configured to apply a drive signal to a driver circuit to control the operation of the mowing electric motor. The controller is configured to receive a first electrical parameter related to the current of the mowing electric motor and when the first electrical parameter satisfies a first preset condition, limit the first electrical parameter within a preset range. When the first electrical' parameter is limited within the preset range, the controller is further configured to selectively use a first method or a second method to determine the rotor position of the mowing electric motor so that the mowing electric motor does not stop when the first electrical parameter is within the preset range.",
