If everything is dead, it's either the main fuse, battery. or a battery cable/terminal.

The main fuse is taped to the wire bundle near the starter and usually wrapped in tape. Check it.

You can test the battery/cable with the brute-force starter test. Be sure you are in neutral before trying this. If the starter cranks good during this test, the battery and battery cables are OK. If it doesn't crank with vigor, dig deeper into the battery and cables.

If you hope to diagnose electrical problems you really need a multimeter (volt meter) and to learn how to use a schematic for diagnosis testing. Sparks mean almost nothing.

I had the exact same thing happen on mine this summer. Had my wife turn key while i jostled battery wires. It turned out to be the positive battery cable. I ended up having to add 2 washers to the bolt and tighten it down real good. Has not happened since.

Well, I had cleaned and inspected the ground, but since I've never before experienced an issue with the positive side, I was lazy and just left it. When I saw your note, I rushed back out and did it right...and everything lit up and the engine started up just fine!

Thanks to all who replied to my plea for the diverse suggestions; now, if something like this happens again and battery wire maintenance doesn't do the trick, I'll have a bunch of "Plan B" alternatives waiting in the wings.

I also will look for a good sale on a replacement for my dead VOM, so I can do some electrical/electronic diagnostics when I really need to.

This turned out to be an embarassingly basic issue; I'll try to post something really seriously wrong next time!!

Remove your battery terminals and put grease on them and re-install them. This will keep them from getting corroded in the future. I have been doing this for over 40 years on vehicles and have yet to have one fail for that reason. My dad taught me that trick.

Glad to hear you got it up and running.

I had a similar problem recently. Only way I could start mine was to push clutch and hold key in start position. While holding key in start position, very slowly rotate PTO knob towards the engaged position. PTO switch was faulty. Full PTO off and the tractor would not crank. Slight rotation and it came to life. Pulled my hair out trying to figure that one out.
