I tried to use this on my brand new lawn which was seeded (i.e., not sodded). This was a bad idea and did not work. As soon as the ground beneath the Rain Train was damp, the front wheels started to sink into the ground. Before long, it stopped moving forward and the front wheels were completely sunk in.Because this thing is pretty heavy and the front wheels are very narrow, I cannot imagine this being usable for new seed-based lawns. Maybe it would work fine with sod.I will clean the mud off and store it in my garage until I have grass and try again and update my rating (probably next spring). Back to pulsating rotary sprinklers! I'm trying my luck with this one:Gilmour Extra Large Coverage Sprinkler #999ZS
