Can anyone tell me what size

battery I would need to have on a dolly in order to jump start tractors? I have been to a lot of auctions and have seen the cart dollies they use to jump start the tractors, but I never paid any attention to what size battery they have mounted on the cart.

Now, I have seen them jump Ford 8N's that have a 6 volt starter system, and with the same unit jump start the big 12 volt tractors. How does that work?

Thanks in advance,
Tuf

If you jump a 6 volt battery with 12 volts you might run the risk of blowing the battery up. Also, if you jump a 6 volt system go to the frame with the ground and then to the hot side of the starter. If you go through the electrical system you may burn out the coil. I learned this after about 4 coils on the Oliver 88. I don't learn real quick sometimes.

Thanks for all the responses.

It sounds like I can use a 12 volt battery to jump a 6 volt as long as I do it fast.

Rhudson, what is a float charge? Sounds like you have done what I am wanting to do.

Thanks,
Tuf

a float charger is one that keeps a constant, but small current charge on the stored battery. usually an amp or less. a smart float charger only comes on when it senses a fall in the battery voltage. it shuts the charge circuit off after the charge is replenshed. its safer for the battery and i would think better for your electric bill. i got mine from Surplus Center for about $25. but i think i saw an even better charger at walmart that would charge at high amps (about 10 amps) or maintain a float charge (kill two birds with one stone) it was made by a company named Vector. it also had that desulfination feature that some of the fellows have been taking about at this site.

i was thinking about your project today while i was bushhoging. my cart is a four wheeled cart with a very large battery. i might make a smaller one using a handtruck and marine battery for the small jobs i have around here. i guess its the time of year to worry about such things.

The battery I bought today is large, also. It is a 1000 cold cranking amp battery.

Thanks,
Tuf

You coulda bought 2 of the 6v $30 batteries, put in series & have 12v boost & to recharge, tap off just one & have a safe 6v booster.

If you are always near an outlet, those 100amp bosters with several charging options from trickle to 30amp are really handy, under $90, and last longer than a booster battery, which needs a charger anyhow.....

tuf, i believe you must put the 12 volt pos to the frame of the 6 volt(pos ground) tractor & then place the ground side of the 12 volt battery to the starter pole ( then only for short periods)...its been a while since i've jumped the old jubilee

It's best to bypass the 6 volt when using the 12 volt to start, as 6 volt batteries have exploded. Most 12 volt conversions use the old 6 volt starter without damage. I have an H that was out of time, cranked the 6 volt starter with 12 volts over and over off and on for several days without apparent damage. Due to my own stupidity, I had the gears in the mag off a couple of teeth. You should never run a starter for more than a few seconds at a time anyway, 6 or 12 volt.

i built one of those, nice to have. i used about 15 feet of welding cable for each lead. used a battery disconnect on the positive cable to add a little safety. i make all my jumper cables with one lead about 6 inches shorter than the other, that way the clamps don't accidently short to each other when they dangle down. but on the cart i left the cables seperated their entire length and built seperate storage rack to wrap the positive and neg lead on, again more safety. added one of those smart float chargers to the stand with the idea of keeping it plugged in all the time. as it is i just plug the charger in every month or so or after i have used the cart. later i added a little tool box to keep battery maintenance tools in.

my next battery project is to put up some solar panels, run wires with dropps so i can keep all my shedded junk on a float charge.

You can use a 12 volt battery to jump start a 6 volt tractor, just be careful to not run the 6 volt starter for more than a few seconds, or you could damage the starter.
As for what size battery to put on the cart, I would think that any good 12 volt battery should work, the more cold cranking amps, the better.

You won't hurt the starter putting 12v on a 6v system. What you WILL hurt is the 6v charging system - generator, regulator, any lighting or fusing. As well as cause big problems between the 2 batteries. Hard on the coil, points, & condenser as well, but will take a short time start without much trouble.

Many people do use a 12v jump on 6v - go direct to starter, try to isolate out any other components. Not recommended, but lots of folks do.

The least likely component to be harmed is the starter - they are built heavy for intermitent use, and will handle it fine.
