I think 3 push mowers and a 48" hydro are highly underestimated. I bet once you get going and have a helper you can make really good time with that setup.
I want to ask, I've been thinking my next pushmow will be a Toro Recycler like those you have. I'm guessing they do okay if you have 3 of them. I see alot of pros have them. I'm not impressed with the $1200 commercial 21's at all so just wanted to find out what you thought of them.
