Best sprinkler I have ever used.  The tractor is heavy  but I have a very large lawn, 1-1/3 acre, once I set it up all I have to do is move the hose every couple of hours and it just keeps trucking on.  Adjustable as to the sprinkler area covered and speed of tractor so you can get just about amount of water coverage you want.  This is my second one and they lasted over 15 years.  Well worth the price if you have a large area to water.
