Takeuchi TB240

[RyeRye]

Need some help, I have a TB240 that starts and idles up, but will not move. Its throwing an error code 612, and it beeps and has the exclamation point flashing. I have checked electronics for moisture, nothing looks cracked or broken. It was working just fine days prior to this happening.
Suggestions...?

I’m having the same issues TB 240 and
codes 612
8005. Takeuchi says it’s the main harness but I don’t want to just throwing in.

I'm having the same issue and I have spent the money for the harness and it still is doing the same thing!
