This reply is for Hugh McKay. Hugh, you are just kidding about it taking four hours to push over a tree, any tree, with a D7 aren't you? Way back in the early '50's my dad and his employer had a TD-14A with a Bucyrus blade and they cleared a lot areas of the trees....elms included. A TD-14A is nowhere near the tractor a D7 is. Now if the elm was 40" or more diameter at the stump it might take an hour or so to rip away enough roots and then build up about 8-10 feet of ramp to push the tree over. But I can't imagine any tree taking 4 hours to flop unless the dozer operator had no idea how to go about it. Every respectable make and model of farm tractor built since 1940 equipped with a standard drawbar and the load hitched to it...not the three point hitch, like the Ford/Fergys, can pull for all it is worth and not be in danger of rearing over backwards with sensible operation. It's inexperienced novices, plain fools or pullers caught up in the heat of battle and should know better that have accidents pulling with tractors. Some old relic tractors like Fordsons were dangerous because of the stupid design of their drawbars/hitchpoints but after 1940 all the major makes had safe drawbar design to make rearing up impossible unless something stupid was done to leverage the tractor to make it rear up. If the operator is stupid enough to jerk the load so fiercely something breaks in the drawbar linkage, or weights the rear of the tractor excessivly, especially with weights not designed for that tractor, that's a different story. Did they put a "safety tractor" on the front of tractors to hold them down when they drawbar tested them at Nebraska? Fools can kill themselves with a fly swatter.

Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. 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
