From the 'operational' view...
You're better off with buying a 3PH 'carry all' implement. Far cheaper and better.
If you use a 3PH to QA adapter, you reduce 'payload' by the weight of the adapter. Also ,you have 2 hookups and unhook operations every time you use forks out back. It's also longer ( away from tractor).
With a carryall, one operation to hookup, 1 to unhook. Also increased payload and closer to tractor,so easier to carry.
First implement I made was a 'carryall' using forklift forks. Easily carried 3000 logs and got rid of the loader up front. Learned to double skid 'stuff' real fast.
