Anybody take the plunge and go cordless for their yard? My yard is a standard size lot but my Bermuda grass can get really thick if we get some good rains and I don't mow it twice a week. Current mower is 20 years old and starting to burn oil and parts are stating to fail. Was going to go ahead and fork out the big bucks and get the crème-de-la-crème hoochie Honda gas mower, but....do I really need to shell out 700 bucks for another gas mower? Heard the biggest problem with cordless mowers are battery longevity. Wonder if any of ya'll have had experience with these. I probably cut 35 times per year.
