I just bought 3 acres of pasture I'm building a house on...I want a ZTR mower to make ease of my future mowing duties. I've heard great things about all 3 brands of ZTR's but what is the deciding factor? I want a mower that will last me a very, very long time and is maintenance free. I don't want to be hauling the mower to the shop every couple weeks. Let me know what some of you commercial guys think about my purchase choices...Thanks!
