Electricity

Electric mowers are further subdivided into corded and cordless electric models. Both are relatively quiet, typically producing less than 75 decibels, while a gasoline lawn mower can be 95 decibels or more.

Corded electric mowers are limited in range by their trailing power cord, which may limit their use with lawns extending outward more than 100–150 feet (30–45 m) from the nearest available power outlet. There is the additional hazard with these machines of accidentally mowing over the power cable, which stops the mower and may put users at risk of receiving a dangerous electric shock. Installing a residual-current device (GFCI) on the outlet may reduce the shock risk.

Cordless electric mowers are powered by a variable number (typically 1–4) of 12-to-80-volt rechargeable batteries. Typically, more batteries mean more run time and/or power (and more weight). Batteries can be in the interior of the lawnmower or on the outside. If on the outside, the depleted batteries can be quickly swapped with recharged batteries. Cordless mowers have the maneuverability of a gasoline-powered mower and the environmental friendliness of a corded electric mower, but they are more expensive and come in fewer models (particularly the self-propelling type) than either. The eventual disposal of worn-out batteries is problematic (though some manufacturers offer to recycle them), and the motors in some cordless mowers tend to be less powerful than gasoline motors of the same total weight (including batteries).
