Yes, you can run an 8 volt battery in a 6 volt system and it will charge with no other modifications. We did it for years with a Farmall 300.
Thers a good chance YES it will be okay, butttttttttttt that depends on what charge control system it currently has:
If its a simple 2 wire Cutout Relay and LHBD light switch, it will still charge ALTHOUGH NOT AT ANY SUPER HIGH RATE
If it has a Voltage Regulator that uses a "current" regulated field control relay YES it can still work
If it has a VR that uses a "voltage" regulated field control relay IT NEEDS ADJUSTED
Why can it still charge?? basicaly a DC Generator dotn know what its output voltage is to be specifically, it increases EITHER if it turns faster ORRRRR you pump more current through it Fields, which is what the VR regulates.
IM NOTTTTTT A FAN OF ODD BALL JURY RIGGED 8 VOLT SYSTEMS. Its a band aid approcach to fix the real problem. On 6 volt I recommend use of the absolute biggest heaviest highest rated battery that will physically fit,,,,,,,,00 Gauge battery n starter n ground cables
Thats my story n Ima stickin to it

I vote for John T's position. AM M with a Proper set of 00ga cables will turn over fine. If it has a shaved head, big domed pistons, and other modifications it should be 12 volt real conversion. 8 volts is just kinda like putting a cheap whiskey on ice cream. You eat it because you made it, but you really don't like it at all. JimN

Yes, a lot of people have been using them for years without problems. The downside is, a lot of dealers don't stock them anymore, and they are getting pretty cashy.

Simple answer is yes but in the long run at best it is a band-aid fix for other problems. 6 volt system have worked for decades and do so now. Big problem with an 8 volt battery is have you ever seen an 8 volt battery charger in the stores????????????? So if you put one in how do you charge it. Plus your 6 volt system at best unless you have some mods. made will only charge that battery to 7 or so volts so then you still are not better off. Stay with 6 volts or switch to 12 and be done with it

thanks for the advice everyone. Im gonna try the 8 volt with bigger cables too. It just turns soooo slow with a 6 in there. I prefer original systems myself (I drive an unrestored 31 Model A truck with the orig 6 volt system) but when Im out harrowing and the M wont quite start it sure is aggravating. Im the only 36 year old guy around here who farms with and drives 70 plus year old equipment. Thanks, TJ
Lot of people will try to tell you "If the rest of the system is good, 6V is all you need." May be, but if you don't have the money to completely restore the entire electrical system and engine to like new condition, why not use the added volts? I had an Oliver S-55 for years and when I could find an 8V, I used it. The 6 volt worked fine for one year, maybe 2 winters if I was really lucky and started the tractor every few days. 8 volt would last 4 to 5 years and I didn't have to start it every few days. Then it got to where I couldn't find 8 volt batteries around here without special ordering. Didn't do a thing to the voltage regulator.
