The latest issue of Ageless Iron mentioned the latest John Deere Tractor has 850 horsepower and then mentioned the first Waterloo Boy tractors JD made were 25 horsepower. Tractors have sure come a long way since the 1920's. I'm sure every other manufacturer has a similar story. I've read stories where early 25- 30 horse tractors didn't sell well for a few years because they were considered too big. Now it doesn't seem like they can make them big enough. I'd love to drive one of the big ones but I sure don't want to pay for one of the big ones. I guess I will have to keep my Farmall M a few more years. LOL
