The neighbors down the street bought one of these and when i heard about it i thought yeah right that thing wont last
But was i WRONG this thing works great for a battery operated push lawn mower its called a neuton .
http://www.neutonpower.com/I got one for a ya whats funny about my riding mower ranch king MTD lawn mower i bought that like back in 88 89 and its still cutting great i put new cutting blades a few times & drive belt on it and deck pully wheel and fixed the ignition switch on it and put a couple different batteries in it but its still going strong
i paid 800some dollars for it and I noticed my neighbor has a new John Deere after i got back now and i just have to laugh since then my neighbor has had 4 different lawn mower tractors in the time ive had mine and some of them werent cheap by no means and were better brands than mine and we got the same amount of grass to cut actually we got more we cut
and here my old frame model ranch king is still going strong

this pic is similar to mine
