Long story, but I have a 60" pin on and a 54" ssqa bucket for my 2650. You will appreciate the extra width of the 60 for sure. My 2650 has no issues with a full 60" bucket of gravel. It all comes down to ballast on the back and using your head when lifting things. I got the 60 to use from my dealer because the ssqa mount was on backorder earlier this year. I ordered the tractor with the quick attach 54, but due to the delays on everything, the dealer couldn't give me an answer as to when everything would be in. I used the 60 to move over 100 yards of topsoil and 35 yards of gravel. It had no issues. I ended up buying the 60 pin on for $250 from the dealer when all of the stuff finally came in to set up the quick attach. Now that the ssqa setup is on, I love the ease of changing between bucket and forks, but really miss the wider bucket. I can obviously still put on the 60, but I loose the quick attach feature. I was in a unique situation, but I did get to use both sizes back to back on the same machine and can give you actual real world feedback.
