Can I replace 6 V batteries w/ 12 V in a Farmall 560D

The batteries have always been a problem on the 560D, since all the newer tractors come with two 12V batteries hooked in parallel, why wouldn't this work on this tractor. I know enough to switch the series arrangement to parallel. Is there any other modifications that would be necessary? It's 12V either way.

Any comments or experiences will be apprectiated.

Then, this summer the generator quit so I converted it to an alternator and negative ground. Same two batteries, still doing what they're supposed to.

Also, I've run two 12's in parallel on a 4x4 pickup with a snow plow on it for years, for the extra amperage both for starting after it's sat for a month in cold weather and for running the lift on the plow. No problem with that, either.

Most diesel pickups come from the factory with two 12's in parallel. If there was an inherent problem with the setup, I doubt they'd to it.

I'd say go ahead with your 560 if you want.

Yall take care now, fun discussion

I just removed a 6 volt battery that gave me 13 years service here in Canada. I have started 6 volt gas tractors without starting aids at -40F. Very rarely do I not get 6 or more years from a battery, 6 or 12 volt. The key is battery, cable and charging system care.

Id use at least a 900 preferably a 1000 to 1100 CCA heavy duty 12 volt battery. Unless its extremelyyyyy yyyy cold or the tractors worn out n hard to start, I dont think you need two 12's in paralell really as a single good heavy duty 12 ought to do the trick, but if not and you want two 12's for more cranking ampacity, buy them new equal n matched to lessen the situation of one feeding off the other.
