I have owned the Nelson Raintrain for two seasons. With just a little experimentation I was able to get the tractor to navigate nearly all the turns in my lawn. I learned that I could attach an unlimited amount of hose to reach the ends of our property as long as I periodically pulled hose to prevent the trailing length from becoming too heavy. No constant moving a sprinkler from one spot to another and it had the good sense to shut off automatically when it was finished. It's now in the landfill.
