Makita has come out with one. It's just a matter of time. I am going to splurge & get a M18 setup to have a pole saw with extension, edger, hedge trimmer, & blower (for quick deck/patio cleaning). I'm thinking that Milwaukee is putting together some mower but they just haven't made what is up to their standards.
Snapper has an 82v mower that is push or self-propelled but it is nothing like their tradition gas mowers. Now Toro makes a high wheel recycler mower that performs just like the gas version. I think Toro has the best battery mower line up right now because they literally kept all the same deck & drive components, just made it battery powered. I cannot for the life of me figure out why the rest like Honda or Snapper didn't do the same. Well I know why Snapper didn't because they are owned by Briggs & Stratton who made a Snapper version for the Wal-Mart (cringe) but I don't see that crowd paying more than $400 for a mower. B&S just filed Bankruptcy.
