After looking around, I bought a 60 inch Scag with a 26hp Kawasaki engine in 2010. The first couple of years it was amazing, but then electrical gremlins started up and it became more and more of a challenge to get it to start. I have now completely bypassed every safety switch, and to start it, you turn on the key, and then touch two exposed wires together. It now starts up every time that I want to use it, but then the PTO Generator went out, which was another pain in the rear. I've replaced the switch to activate the blades three times now. I also expect the through one, or both of the belts the first time I activate it when heading out to mow. It's not hard to put the belts back on, it's just frustrating to know it's going to happen fairly often. I also had the starter come loose several times and require thread lock to stop that from happening any more. Because of the electrical issues, I can't recommend it.
What I like about it is the amount of power it has, the ease of operating it, the comfortable seat and the solid front tires. I've had a few flats in the rear tires and it's always frustrating to deal with that. The blades are super easy to change, but the under side of the deck needs some serious scraping a few times a year. It has two separate hydraulic pumps that will probably bankrupt me if I need to fix them, but so far, that part of it has been excellent.
I go through 3 sets of blades a year. I don't sharpen them, I found that to be a waste of time. I've also found that for me, the factory blades work the best. The high lift, mulching and bahia blades all create too much dust and the cut isn't any better then the factory blades. They don't last any longer either.
