Electric lawn mowers remove the need to fill gas tanks and tolerate exhaust fumes. They are also quieter than gas powered models, and by doing away with the exhaust they have less environmental impact. Some are powered by a cord which needs to be connected to an external power outlet. This can be a beneficial option for smaller yards where the length of the cord allows the mower to get to every corner. On the other hand, rechargeable electric mowers remove the limitation of the cord, but it is important to make sure that the battery life is sufficient to allow for the entire lawn to be mown.
