If your at all familiar with the JD 30-40-50 series two wheel drive tractors, the stock setup is two 6V batteries, one on each side of the frame, connected in series.
My experience with my 4450 JD and many other farmers on a couple of farm sites with those same series of tractors, is that replacing those two 6V batteries and long connecting cables with a simgle 12V, as high a CCA as will fit in the box, will make them crank faster than the double 6V setup ever did. If the tractor needs to start in very cold temps, then you put a large 12V in both boxes and connect them in parallel with 4 cables to the starter(2 grounds under a starter mount bolt and 2 "hot" leads connected to the "bat" solenoid terminal. You get far less voltage drop with the parallel 12V setup and faster cranking speed. That exact parallel 12V setup is factory original on the JD 55 series and is a popular retrofit to the earlier 30-40-50 series.
