OMGX21647_K3 scroll down left side of page to troubleshooting & see electrical, if you have a battery charger charge it up with positive & negative cables removed then take battery to local auto parts store & ask them to load test battery, there should be no cost to you & this will let you know if battery is good or bad. If battery passes load test & your tractor has many hours run time along with age your problem is possibly alternator under flywheel and or diode in wiring harness. Check all ground cables & straps as well as all connections by hand making sure everything is tight & secure.
