Would start at the key switch work my way down the wiring harness.
Sometimes those buggers can lose some juice they are just cheap electrical components.
They get corroded and they go bad.
Then work my way through the wiring harness to each electrical item.
I agree the PTO could be the issue also.
Older riders use to have a diodes right before the starter. The unit went to three shops and I just took my time finding it. Electrical gremlins sometimes are not obvious sometimes they are.

OP.
Fully charge battery. Only put negative cable on. Tap positive to the battery pole. It should spark a little if there's an amp draw. Start unplugging each component one by one while doing the tap trick until there is no longer a spark. Now you've found the component that's causing the draw. Not everyone has an amp meter so this is a safe way to test.
