What are the basic differences between the two models? Good bad or ugly???!!
I believe the majority of the B2 was improved undercarriage components that included caterpillarized bearings, seals, and more replaceable parts vs the original ASV undercarriage. I think there were also some switches moved to the joysticks from the overhead panels. This was the same time the C's came out on the larger machines, and some of the cab features were made common.
