I have a b2601 and use the Speeco quick hitch from Good Works Tractors - it works on all I have. I had to modify my boom pole by using a chain on the top of the connect, but the bottom pins fit, and it gives me some more adjustment for lifting stuff.
If my stuff didn't fit, then I'd go with the Pat's like others said. They seem to work well on stuff.
