Tractor
800 ford
Yesterday I went to borrow an auger from my neighbor. The tractor was running fine, the neighbor even mentioned how good it sounded, etc. I turned the tractor off, back on, then off while hooking the auger up. Next time I tried to start, it was silent. No cranking at all. Just a slight sound from underneath the hood. We tried jumping from his tractor. Nothing.

I removed the Walmart battery, brought it home and tested it - showed 12.2 on the voltage. I charged it for a while - put it back on the tractor - still wouldn't even crank. The battery was over 3 years old, so I removed it again - took it to Walmart to test it. They said the battery was okay, but needed charging. The read out showed 206 out of 540 cca? I charged it up to 12.6, re-installed with still no results.

I suspected the starter, so I removed that (had to take the oil filter off to get the starter to slide out), brought it home, hooked it onto my charger and it turned as it should. I'm going to reinstall the starter, as well as the charged battery, and hope for the best. But if it still doesn't crank, I don't know what to do next.

The tractor had been converted over to 12 volt by a previous owner, who indicated that the battery needed charging frequently in order to start the tractor. I have owned it for 2 years and have to charge it occasionally after several hours of use. Otherwise, no problems with this old tractor except slight leaking of rear end.

I could use some advice. I'm not a mechanic, but I am learning by trial and error. Thanks.

Check your ground cable where it attaches to the chassis, and make sure it has a good connection by removing, and cleaning.

That's a good point. I re-installed the starter and the fully-charged battery - tractor started right up. I'm going to check the ground connection as you suggested. Do you think this would cause the battery to not receive a charge while the tractor is running?

Could be the connection at the starter was not making full contact, if it started right up. Still won't hurt to check the ground connections.

I'd say if it showed 12.2, after a couple short runs re-starts, things are working pretty decent.
