RIO defeat: OK. Stupid thing anyway. But I would never bypass my seat switch, no matter what a PITA it can be. Obviously both are just normally-open switches that are easily bypassed with a jumper to make the circuits permanently closed. Easy mods.
I agree the RIO is stupid. I wish the seat safety was only active when the PTO was engaged and would only disengage the PTO if tripped. I ended up bypassing mine as I kept killing the engine using the cart or loader.
