Big Tractors Plowing at 100 Years of Horsepower

[@formerfarmer1718]

These big re-powered tractors are a very good testimate to the John Deere drivetrains. From the 4020 (my neighbor had a re-powered 4020 PS with a 555 Cummins) all the way up to the big JD 4WD tractors those JD transmissions, differentials and finals just take it. That’s why you seldom see big re-powered tractors that aren’t green.
