Since you are getting a BH, maybe this will help.
I had a Scut Massey 2310,
B2920, and currently a
B3300, each had a backhoe and among other reasons, primarily I traded up each time for increase in backhoe capabilities. The
B2920 was the same size as the
B2601. I had the BH65 on the
B2920, which only had slightly more power than the Massey 2310 BH but was a heavier build. Btw, the Massey backhoe, stabilizers and tucked in three point hitch and its's power was impressive for it's size.
The BH65 has since since been upgraded to the BH70. Check out current specs between the two on Kubota's website.
The
BH77 on the
B3300 was a step up in capability with full bucket rotation and swing with more bucket curl power. The size between the two tractors when you get them on your property will be negligible. That was a misplaced concern I also had at one point in time.
Less than 10% between the two? IMO, the only other consideration is mmm decks as expressed by Milo, which I suggest you research a little more to your satisfaction. I did look and it appears the deck for 2601 has drive over feature while 2650 deck does not, but I would confirm that with dealer. The
B2650 would be my choice for what you outlined, but I didn't have mmm with any of mine. Good luck with either choice!
