I ordered the system after hearing everybody talk it up and I have mixed feelings on it so far. Out of the three implements I use the most - box blade, tiller, shredder - it only works on the tiller. The rectangular guard on top of the easy change hits the braces on both my shredder and box blade. I can trim the braces with the torch and make it work on all of them but from what I read I thought these worked on darn near everything. I really would have prefered a true quick hitch but I did not want to have to modify my implements but it looks like I get to anyway.
