RPM gauge dropped to zero tractor won't restart

[Glynis T]

6340 ZETOR. 65HP. I just had block heater plugged in. Unplugged. Started no issues. Then the RPM dropped to zero like a rock. Tractor still running fine but I turned it off. Then tried turning it back on. NOTHING. Won't turn over, not a click, no lights, nothing. (I cannot pull start, as there is a 6ft snow drift 4ft in front of the tractor). Any help would be appreciated while I wait on battery booster to charge (cause the trucks buried in a 4 ft snow drift at the top of the driveway so no easy boosting, just shovelling, so much shovelling).

Sounds like battery cable issue. Engine will run without battery after it started, but cant restart. And gauges will not operate without battery current. Check all battery cable connections and make sure you cant twist the battery terminals by hand. Check all fuses, especially if theres a main system fuse.

Don't many tachs hook up to the alternator? I'd look around there for issues and fuses
