I found one in good shape for a deal but I have a few quedtions.

Is it a 3pt or subframe mount.

BT650 was the backhoe attachment for the B20, a commercial grade TLB based on the B series tractors. The backhoe was frame mounted to the B20. Since the B20 was considerably reinforced over its B tractor cousins, I would be somewhat surprised if there were a bolt-on subframe to mount that backhoe to a standard B. Worth checking out though. That should be a good little backhoe.
