Call the guy back and ask him to go out and check to see how many caps are on the battery. 3 caps=6 volts. 6 caps = 12 volts. Gamble the 35 bucks and buy the proper battery before you go and change it out when you get there. Bring a 95 cent can of either too. 35 dollars is very cheap compared if something goes wrong.

What he [Claus] said.

Take along a six volt lantern battery. It is likely that the tractor battery is dead as a post and may not have enough in it to power the ignition. If you use cables to power the starter the lantern battery will run the ignition for a long time.

If you jump to the starter [recommended way] make sure the tractor is in neutral as you are defeating the neutral interlock.

Don't put twelve volts on a six volt battery unless you want to wake up the neighbors.

Your mileage may vary

So I put the positive pole of my jumpers on the frame of the tractor and the negative on the wire are the top of the starter? There is a little light in the lights of the tractor when we turn the key on and turn the lights on and it clicks but does not have enough juice to turn her over. it is a 6 volt battery and pos ground, I confiirmed that but was a little unsure of what to do to start her. She's someone elses' still, you understand. Hate to wake the neighbors with someone else's tractor. And she's sititng right next to a little church so this morning would not have been a good time to experiment.

You have it right - BUT CAUTION - Do not push the starter button while the 12 volts is on the starter. It will back feed and be the same as hooking up the jumpers across the 6v battery.

Good luck - Jack

If you jump directly to the starter motor, it does not make a difference if it is 12 or 6 volts or polarity for that matter. The key must be on to accomplish this and there must be sufficient energy in the tractor battery to furnish current to the ignition circuit. Ensure that the tractor is in neutral. Usually you can tell by the telltale alternator but it is possible that it has a 12 volt generator. 12 volt batteries also have 6 cells as opposed to the 3 cells of the 6 volt batteries. Whatever you do, do not jump to the battery with a 12 volt battery if it is 6 volts. This could cause unpleasant consequences.
Happy motoring
