4 rotor double engine 13B powered tractor!

Thats right, it wasnt a typo!  Check out this twin engine 4 rotor tractor.  Its powered by two 13B engines joined in series.  Coupled together with a sprocket and chain, and coupled to a jatco automatic transmission and ford 9" diff, this tractor competes in tractor pull events where the name of the game is to haul a heavy weight over a certain distance in the fastest possible time.
