It's a very cool rag if you are into "creative welding" and fabricating. As you have probably read in here, I have built my own aerator and 40 gal fish feeder for dirt cheap with a gast science (oiless) air pump and a Remington scatter feeder. My motto is, Whatever Works... The weed-eater-holder-thingy is a simple, home-made, light framed unit with 2 wheels and a handle. It has 2 vertical "stands" that the weed-eater clamps onto, holding the weed-eater at the same angle you normally would, letting the entire weight be held on the wheels. You then use it in the same fashion as pushing a vaccuum cleaner around. It's actually quite functional, and more so the older I get. ;\)
