I have a 2012 1026R that has that RIO on it. I disabled mine by making a little bracket out of sheet metal to permanently make up the reverse pedal position sensing switch. I did not want to cut wiring and jumper stuff. Right under the front of the seat there is a plastic black cover that you can easily remove. you have to remove the three point speed knob with an allen wrench, and the deck height of cut knob( it just pulls off). With the tractor shut down you can then actuate your reverse pedal and see the linkage move off the switch. All it takes is a little "L" bracket and a couple holes and you can bolt it right on the switch bracket in the same holes as the switch using the same bolts. Very easy to do. I'm getting ready to trade mine in on a bigger machine and I will remove this so that the dealer doesn't have to.( I'm sure they will check that upon trade in). But I am still only assuming that the 1025R has the same setup. If it is not I apologize. It definitely makes it better when mowing without that ignorant feature lol.
