The Toro 22" self propelled shat it's drive system. I used it for a year after, but it got too heavy for us. Then we bought a Worx battery operated mower. It is all plastic, so very light. But it only has an 18" cut. I keep telling the wife I'm going to buy a riding mower but she keeps vetoing that idea.
If you can mow a 1/4 acre with a battery, in one day, I'd say your doing pretty good for an ol' fart. Or, I'm just more of a worn out old fart than I should be.
