Converting farmall tractors from 6-volt to 12-volt is easy to do and ultimately will result in a better running machine as well as a more reliable electrical system.
The Farmall model H tractor can be converted using a model M conversion kit. By modifying the alternator bracket and using the right sized belt the alternator will fit under the hood. The original battery box can be used to hold the new 12 volt battery as well. Just measure the box and go to your local battery store to find one that will fit. By doing this you can ensure the original appearance of the tractor while modernizing the tractor for show, pulling or farm work.
