Here is the 370hp straight 6 Cummins power plant these PB's have. As you can see, its turbo charged.

Here is some drive motors, pumps and sprockets. This unit as three pumps, as seen in the 1st photo. Alpine units would have 4, another one for the tiller.

I know Houghton gets a bunch of snow so what sports are you supporting up there with these machines?

I went to school at MTU and my cousin lives in Ripley for many years!

The pumps are piston / constant flow? Any idea what brand? (Eaton, rexroth, Kawasaki?).....

370 hp seems like a lot for grooming trails, compared to what some semis have. Jon
