Starting on 6 Volts

SadFarmall · Apr 20, 2012

Successful starting on 6 volts! Good wires, good contacts, good starter motor and one large 6 volt battery from a K113 Scania bus. The bus is 24 volt, and uses 4 6 volt batteries, so I asked work to order an extra one for the Farmall M… magic.

They do roll over on 6v is the cables are big, and the battery has good capacity. Very nce. Jim

Unlike an H or B or C etc., I cut guys a little slack (the dudes who wanna convert to 12 which I discourage) when it comes to starting an M at 6 volts.

Similar to what Professor Jim tells ya I advise:

00 Gauge Battery n Starter n Ground Cables

The ground to a heavy clean frame member using stainless hardware or even a 00 ground cable right at/on the starter versus any thin wimpy or rusty sheet metal

Biggest heaviest highest CCA rated battery that can possibly fit

Good starter switch

Tractor tuned to perfection (especially start timing) with light or multi viscosity oil and clutch depressed and any possible mechanical loads like hydraulics OFF while cranking

Hold your mouth to the right while cranking and I found it best to sort of milk them up over on compression one piston at a time versus just holding the starter down n letting her crank n grunt till the batterys is near dead.

Thats my story n Ima stickin to it

I agree! Though as it does not get really cold here, like North America, 6 volts is not too much of a problem on an M.
