There's only 1 diff under it. Really really big diff. But only 1. The axles come out and power the final drive planetary which in the center of the chain case. And the planetary has 2 sprockets on it for the chains. 1 chain to each wheel. There's no suspension, but the chaincase articulates around the final drive. So front tire goes up, rear tire goes down.
Okay, that's about what I had pictured in my mind ... I figgered the chains to be farther out towards the sides, not so far in towards the centerline, but otherwise, yeah. That is some SERIOUS drivetrain, but then when you're moving that much weight of equipment plus the load of whatever it's pushing ... yeah, you need more than a 14BFF
