Hi Max,
I just think they are not smart enough to mow lawns, it is not just as simple as just pushing a mower around. Yes I know about contractors keeping their Hondas for 12 months and then replacing them, sure wish I could find those motors and put them on other bodies, they have years of life left in those motors. I have seen the front of the bases worn through just from gravel etc hitting it from the inside. As for mowing lawns, those days are behind me, my legs are not up to it. Fixing the mowers I can do in my own time, it is just dealing with the Gumtree people that gets to me at times
