Had 20 minutes of daylight to get it uncrated, attached and to dig something.  The crate top was held on by 4 bolts and then I was able to just lift and shimmy the bucket through the bottom part which has the vertical supports tack welded.  I hooked up with no issues and the attachment point is perfect with the ssqa (as it should be).   I dug out four large rocks / small boulders in the 1-2' range with ease.  The hardest part was getting the rock up in the bucket.   I would normally just pick-up and move stuff with the grapple, but this worked.  I stuck it into the ground just to see how easy it would dig, and it ripped into the ground like butter.  When it dries out, I need to go after a few of my stumps and see what it will do.
Two features that would have been nice are drain holes in the bottom/back for water to escape and the tabs or hooks for a chain.
