I just bought 3 acres of pasture I'm building a house on. I want a ZTR to make ease of my future mowing duties. I've heard all 3 brands are solid, but what is the deciding factor? I want a good mower that will last me a very, very long time and is maintenance free. And I definitely don't want to spend a lot of time hauling the mower back to the shop every couple of weeks. Let me know which brands some of you experienced commercial guys have had the best luck with...thanks!
