This category includes some battery lawn mower models fitted with electric motors that run thanks to rechargeable batteries. These cordless lawn mowers don't have to be connected to a power outlet by means of a cable like classic 230V electric lawn mowers do. Cordless lawn mowers are very popular among operators that seek great user comfort and want a lawn mower that doesn't require the regular maintenance operations a petrol lawn mower requires (oil check, filter and spark plug maintenance and so on). At the same time, battery lawn mowers don't require a power cord to operate. These battery lawn mowers have various cutting width options based on the model, from 30 cm to 50 cm. The smallest model (30 cm) was designed for small areas, while the larger models (50 cm cutting width) are suitable for average-sized surfaces. Some of these cordless lawn mowers feature a rear-wheel drive system: a unique feature in the cordless lawn mower or electric lawn mower field.
