The knowledge I have about JD tractors could be put in my ear and I would never know it was there, but I love tractors. So Saturday, 1-10-03, I watched a 1/2 hour program about the building of a JD tractor in their Iowa plant. They even showed the pouring of the mold of the engine. Then step by step of putting the whole thing together. I'm not sure about the horse power from the 6 cylinder diesel engine, but I think they said 150. The frame and engine without the tires weighed 18,000 lbs. It even had a GPS device and a computer that when it was set, you could let go of the steering wheel and take a nap while it was plowing. The seat checked positions 200 times a second and you aren't supposed to feel the ride at all. It showed how Mr. Deere got started by inventing the S.S. plow point to keep the sod from building up on it. My wife said "no, you can't have one because the disk it is pulling is bigger than the whole place we live on". I would love to go through that plant.
