When the first mass market cordless electric lawnmowers came out I was living in California and everyone was buying them. They were heavy and had a sort of retro Soviet design. I'm glad I waited, although when you consider that one older gas mower can pollute as much as 3 cars, it mightâve been good to make the jump sooner.One of the best features of the B&D cordless mower is how quiet it is. I donât need ear protection and I can use an iPod without cranking it up to Uber Loud. The mower starts instantly with the pull of a switch. My clothes never reek of gasoline. There are no oil changes, tune-ups, winterizing rituals or fuel spills.The mower runs for about an hour on a single charge, so I can cut about one third of an acre without running out of power. The only propulsion it has is from the muscles of the operator, so if you have a rolling yard youâll want to be in good shape. But itâs kind of a nice way to get rock-hard glutes.The lead-acid battery recharges up to 60% in about 4 hours, and to 100% overnight. Thereâs no assembly other than a couple of wing-nuts. The safety key thing is a little arcane. You have to turn the provided key after inserting it into a receptacle just below the switch lever; otherwise the mower wonât start. You charge the mower in the same location by removing the safety key and inserting the DC charger cable.
