Although the lawn type narrows down the choice of suitable mower, you must also consider convenience. Power source (you or an electric motor or a petrol engine), size, weight and ease of control are just a few of the things to consider.

Electric

Look for a long flex (to avoid the need for an extension lead) and a gadget to keep the flex out of harm's way. For example, Wolf's flick-flack device automatically moves the lead to the correct side of the mower when you change direction. Cordless mowers (which use rechargeable batteries) don't have the inconvenience or potential danger of a trailing flex.

Petrol

Fuel and oil should be easy to add to the engine, but some fillers are placed in very awkward positions. A see-through fuel tank is very useful to see how much fuel is left and to avoid overfilling too.

Some petrol-engined machines still have to be turned off at the engine, which is inconvenient. Look for an on/off control on the handles.

Starting a petrol engine (2- or 4-stroke) is not difficult these days - but if this bothers you, look for key-start, but be prepared to pay more for this feature. Key-start is standard on ride-ons and tractors; most also have a recoil start as a stand-by if the battery is flat, but be warned, it's not easy.
