A narrow front is easier to manuver in a tight area. On rough ground though youhave to pick 3 tracks for the tractor, while on a wide front end you only have to pick two. A wide front will require a larger area to turn and manuver.A wide front end will ride better as each wheel going over a bump only raises the center of the axle half as much as the height of the bump. As for stability, I don't think when it gets right down to it there is much difference. A wide front pivots at one center point as the axle rotates going over rough ground. The only advantage in a wide front is as the tractor is tilted on a hill side the pivot point of the front end is higher, closer to the center of garvity, the narrow front end piviot is the ground so as the tractor is tilted on a hill side the center of gravity swings out farther from the contact of the front end (pivot point) with the ground. Just think of hanging a string from about the center of the radiator, as the tractor tilts the string will swing out remaining verticle and it will be closer to the pivot of the wide front end in the center of the axle than the contact (pivot) of the narrow front with the ground. A wide front end tractor still is supported on only 3 points is what I am pointing out here. If the wide front tractor starts to roll, the wide front axle may contact the frame and maybe prevent it from going, I would not want to count on this though, by the time this contact happens it is probably on it's way as the tractor would be on a pretty steep hillside or grade in the first place, then with the addition of the angle need for the front axle to contact the frame, I think it is going over at this point. I think it comes down to what you like, what you have, or what you can end up with. Unless there are reasons you have for one or the other.

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
