There are 2 versions of the quick spade, the one for forks which is cheaper and the "combo" unit which is for forks or will slide onto a bucket. I have the combo unit. It is VERY heavy built. I think it weighs about 80 lb. You won't need to worry about breaking it. I have used it to dig some rocks out, help with a trench, and dig out some small saplings. The only problem is securing it to the relaively small bucket on a B or BX. It has a hook on the top and bottom. It is designed to hook a chain (I use 1/4") to the bottom hook and around the bucket to the hook on the top and use a ratcheting tightner to tighten the chain. Even with the smallest tightener, I can just get it to work. Obviously you could come up with another way of tightening it. But otherwise it is a good product. I think I got mine though Northern Tool, but I bought somethrough that weeders website, so it may have been the quick spade. I don't have a BX so can't comment on the power of the bucket.
