shut the 3020 off tonight. needed to restart it for a bit, starter didnt even click. couldnt jump it with a screwdriver either. Let it cool down for 2 hours and the starter works again. all i did was tip the batteries out and check connections so far. not much really to check on the tractor. starter has been on for a couple years, but the tractor only gets 50 hours per year. Anything else to check besides the starter? batteries are about a year and a half old.
