Tractor Sprinkler, where have you been all my life!  for 16 years i have tried various sprinklers and sprinkler systems (like multiple hoses) and I just got tired of dragging hoses around in the dark (I'm in Texas and water at night).  16 years and never knew about this beauty...until my cousin reminded me my Grandfather used to own one.  I bought it and let me tell you, its one of the best purchases I have ever made!  No more dragging hoses (except for set up-but I can do that in the daylight and turn the water on later), the "tractor" does all the dragging for me.  I water my entire front yard in one go--and since I live on a corner lot that means a turn is involved, the tractor handles the lazy curve no problem at all and pulls about 75' of hose with no sliding or digging. The auto shut off is an excellent feature too.  I love the variable speeds, I use "slow" and it takes about 3 hours to do 75 feet--a good, thorough soaking.  I also like the ability to twist the rotating sprinkler bars, I can control the height of the water spray ring with this.  The tractor is steel and I'm sure it will hold up well.  the wheels are plastic, but very solid with spikey grips on it that handle my rarely mowed grass with ease. Overall worth the price.  Do yourself a favor--stop dragging hoses and let this baby do it for you!  You won't be sorry....
