I did not read all the previous comments, so this may have been mentioned before. I have a 2" Trailer Receiver Tube welded to the middle of the top lip of my bucket. Allows the use of 2" receiver with chain hook welded on. Also allows use of 2" Receiver with ball size as required. Handy for moving boat / trailer etc. Quick change.
Also have pallet forks, which I find invaluable. One instance where chain on pallet forks could be used (so far I have just used rope) is for planting trees. Spread forks apart and tie rope / chain to each side of large root ball, one rope to each fork & it is very easy to lift the root ball / tree and set in prepared hole.
The Boom in the pic is more elaborate and stronger, but something similar can be made by inserting the upper tube for a boom in the receiver tube and running supports to the lower lip of the bucket.
