What do you mean?

Petrol mowers?

Excellent.

I have 7 cordless mowers, but they're probably not the type you mean... they are slow-mow: guinea pigs. You just move the grazing arks every couple of hours. ;-)

Make sure you get one that will mow your whole lawn on a single charge. I would say the biggest downside is cost. They aren't very powerful, but they're as powerful as other electric mowers, so they're fine for most home lawns.

I would take a careful look at any rechargeable tool and find out how much replacement batteries are going to cost. These do not have an indefinite life and can cost a small fortune!

I have a battery operated strimmer, the battery lasted about three years. A new battery was nearly as expensive as a new strimmer. You should try and obtain a lawn mower which can be fitted with any heave duty battery if possible

I'd say you're probably better off with a petrol lawnmower if you want cordless use. The new Bosch Rotak 43li however, is a good battery powered lawnmower, featuring new lithium-ion technology it lasts longer than most.

How much grass do you have? I am a big fan of the push mower. Silent, cheap, environmentally friendly and keeps you fit. My neighbour used to spend about 45 minutes mashing up his tiny lawn with a a whiney electric mower during which time the noise was appalling. A hand mower would have taken about 10 minutes and I could have continued to sit in my garden.

We should all do our part to save the enviroment and encourage the growth of the solar and wind power industries. Cordless electric lawn mowers go a long ways towards these goals. I recently purchased the Black & Decker Cordless Electric Lawnmower the CMM1200. I hope my review will help you make a decision about our future.

I'm with Flora - get a push mower unless it's a huge space. Does the job fine.

Sorry, but I don't see why  they are a lot less energy-efficient than a mower with a cord plugged into the mains. Unless you mean a solar-powered mower (lots of magnifying glasses which burn through the grass leaves individually??) or a wind-powered mower (a fast-spinning wind turbine with sharp-edged turbine blades would cut grass very nicely!).
