The no shutdown problem is a bad kill switch ("ignition" switch). Either the switch itself is bad, or the box it's mounted in is not grounded to the tractor frame. (Keep in mind the kill switch works by grounding the magneto primary when turned off so the mag won't send fire to the plugs.)

The dead battery can have several causes:
1 - Battery is worn out and will longer hold a charge.
2 - Charging system has problems and is not charging the battery when the engine is running.
3 - The cutout (or the cutout relay inside voltage regulator if so equipped) has stuck in the closed position causing the battery to discharge when the engine is stopped.
To figure out which it is, watch the ammeter:
If it shows charge when running and 0 when stopped, you need a new battery.
If it shows 0 at all times (running and stopped) either the generator or cutout has failed.
If it shows charge when running but then discharge when shut down, problem's a stuck cutout/voltage regulator relay.
