The effective range of a remote-controlled lawn mower's remote control is usually between 100 meters and 300 meters. Under ideal conditions, the maximum control range of some remote controls can reach 300 meters. However, in actual use, due to factors such as obstacles and electromagnetic interference, the effective range may be reduced to approximately 100 meters.

When the range is exceeded, the signal transmission between the remote control and the lawn mower will be affected, and the lawn mower may experience signal interruption, loss of control, or other issues. To ensure safety and normal operation, when the lawn mower approaches or exceeds the effective range of the remote control, it will usually stop working automatically to avoid potential safety hazards or equipment damage caused by loss of control.
