S.G., No problem with going to a 24-Volt alternator. There are lots of 4020's and 5010's and 5020's with 24-Volt alternators. The problem is, the center of the 24-volt system is grounded to the chassis. For loads like fan motors and lights, you can put 1/2 of the load on each battery. With electronic equipment loads, like planter monitors, etc., the units are polarity-sensitive, and the cases are not always isolated from the power supply wires, so, unless one is very carefull, it is easy to toast these units, either with accidental 24-Volts, or reverse polarity. I believe some of the newer 24-Volt stuff may just have the system gounded at the first negative battery terminal, but a straight 24-Volt system is not without problems, either. I have worked with a lot of the Delco series-parallel switches on semis and industrial equipment, and they are not without problems, either. As I said before, I have no problems with my 24-Volt 4020. It has no cab, and I don't run any accessory loads with it, and I would not gain anything by changing it over to 24-Volts. However, for someone who needs lots of current at 12-Volts, a 12-Volt swap may work out well, if it's done correctly.

When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
