Kubota ZG127 issue, I could use your help sorting

[Hampshire]

Hi everyone,
I suspect some sensor issue. I cant get the mower to start. Battery is charged. I can however jump the starter solenoid and engine starts right up. While in Neutral, PTO off, and brake on. I can hop off the seat, still runs. If I sit down and try and take off the brake, it stops. Same if I pull the handles out of neutral. Some sort of sensor malfunctioning maybe?
Thoughts on what I do next?
Much appreciated.

Seat switch system not working. start circuit includes seat switch

seat switch as mentioned, faulty PTO/interlock switch, parking brake switch or motion/control lever isn't sensing in the neutral/park position. or perhaps a faulty ignition switch.
