Those 3pt drawbars are handy, but they can't be jerked like that. When I was in high school, I took a forestry program, and one of the kids who didn't know any better was using the schools John Deere 5300 to pull full length firewood logs out across a meadow to the roadside landing. This John Deere was a 55hp 4wd with a loader on it. Anyways, the kid revved it up full throttle, and dumped the clutch, with a 3pt hich drawbar hooked to 3 of those full length logs. Now, that tractor had been pulling that many logs, the same size time and again with no problems, the problem was he yanked it hard without taking up the slack in those chains or anything, and that 3pt hitch bar and those 3 chains went flying, it broke that 3pt drawbar into 3 pieces instantly, so it about shattered it. Shock loading destroys stuff Lanse, and even that tractor took a good beating. For straightening out your drawbar, about the only thing you could do is put it down on a hard flat surface and beat on it with a sledge hammer, but you may find it has been severly weakened, and don't use heat!, yes it would straighten out a lot easier with a torch, but it will also weaken the steel much further. Better yet, since we don't want to hear of you getting a concrete chip in your eye or smash your toe with the sledge, take it to someone who has a press, most garages have them.

I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
