C'mon everyone, quit you're complaining. it is there for a reason, to keep kids ,objects and pets from being run over. If you want argue the reasoning, I will galdly give you the number to a woman in our church who backed over her youg son w/ a mower. As they flew him out w/ the blade still embedded in is arm, I'm sure you lazy butt's would say, but that wouldn't happen at my place. I'm sure she thought the same thing. Now the child is mamed for life and a mother feeling very guilty.
My message to you is LIVE w/ IT, DON'T DISABLE. On the Deere, all it is is a momentary "pull-up" or "lift-up" of the switch and then you can let go once you're moving in reverse. You don't have to hold it. It takes no effort, doesn't keep you from turning around and after you get used to it, it is second nature.
I have an X475 that I use every weekend and go through the motion each time I back up. Not a big deal.
I used to be a Deere dealer and I got cussed out way too many times because I couldn't and wouldn't tell someone how to bypass the RIO. And honestly, I don't know how to bypass.
So just get used to it and live w/ it. Remember the small child trapped underneath the deck w/ a blade in his arm and side. It could be your child or grandchild! Sorry you have to be inconvenienced for safety's sake. Heaven forbid.
