If your time is valuable to you, go commercial zero turn. I couldn't believe the difference. I'm running a Grasshopper 223, and love it. My old yard was right at 2 acres to cut, and I could have it all done in less than 2 hrs. Thats including the trimming...which will be considerably less because most commercial zeros have the deck out front where you can get underneath shrubs and bushes. My yard now is considerably smaller, and it takes me about 10 mins to cut it.
