I looked at those before I bought the quick attach type and glad I went that way. Several different configurations (seed, bulk chem, pro boxes, bulk bean bags) all seem to need the forks set a little different, I guess I'm lazy and these move real easy but the clamp on ones might as well. It is nice to have them on or off in a matter of seconds. Either way you go you can't  imagine all the stuff you will use them for. A purchase you won't regret. IMO.
