I have been very happy with the rock bucket, it is extremely stout and well made. It is a little longer than I expected, so if you are running it on a tractor loader, it has a lot of leverage to fight. Otherwise, the quality and price are fantastic, I don't think it can be beat for the money!
I have a Case 1845C, and TYM/Branson 2515R, works well with both machines.
