Tractor is about 10 years old. Serviced regularly, also garaged. Just put a new Battery in. No click, when key is turned. Could be the seat safety switch, or?? Yes, I have new gas, cleaned the plugs, etc. I have it in neutral. Any suggestions? Is there another safety switch somewhere?

Should be a brake switch a neutral switch and a seat switch
Could be any of theses ,
I would start by checking all connections ,ground and positive.
Luck

Thanks! Will check as recommended.

I had the same issue, it turned out to be a stick caught up on top of the deck so that the tractor thought the blades were engaged and therfor won't start. I removed the stick and walla it worked.

Mine just continues with a crancking sound and won't start. Please help and thanks.
