Sqizzy, sorry I missed your post!
This attachment has really earned it's keep! Next to the 4 way bucket, I think it is my most used attachment. I reclaimed a brushy lot as lawn with it, what a great help it was. First I pulled the brush up with it and compressed it, then stacked it for later removal. After making a deep pass with my Harley rake, I then back dragged with the grapple rake and gathered up the tall "Timothy" grass. This area served as the dumping grounds for large rocks that resulting from the house construction and I was able to move them much easier than with the 4 way bucket. A couple more passes with the Harley rake and I was ready to seed.
Here at the house, I keep a steel pile out in the woods, where I toss all my scrap steel such as banding, auto perts, anything that comes along in the course of working. When I get a load, I haul it to the scrap yard. The grapple rake excels at loading the scrap steel, it's much more effective than the 4 way bucket was. As I load, the rake also compresses the banding making for a tighter load.
I cleared an area where I want to build a barn, first ripping up the trees with the hoe, but then I moved them to the burn area with the grapple rake. Again, it worked very well for this application. I've also stacked bulk firewood with it. Glasshousebltr, I think it would work great for the tasks you list. It works better at picking irregularly shaped objects much better than the 4 way bucket does. I'm also surprised at how tough the tines are. I expected them to get all bent up with use, but thus far I've only got one tine that has a slight bend to it. A couple wacks with a sledge hammer I'm sure would put it where it belongs.
Again, I have no regrets over this purchase, it has exceeded my expectations! On a side note, Quick Attach is affiliated with Erskine attachments, the same company that made my snowblower and the quality built in to their products is top shelf.
