I'm a retired tractor engineer and worked on many of the machines routinely discussed here. It is hard to design power equipment for the masses as there are always people on the 'fringe' that really DO need every bit of safety you can design into a product. Some safety devices (like a seat switch) really does offer real protection without much inconvenience to the user.
RIO is a different animal. It doesn't stop a manufacturer from being sued. Any manufacturer with money is always going to be challenged in court. RIO does little to prevent a backover accident either as we all know you quickly learn the 'muscle memory' needed to lift the switch, not look back, and mow in reverse. RIO DOES change outcomes in court though. On every mowing session, on every reverse motion, the machine makes YOU RESPONSIBLE for overriding. Really hard to successfully blame the manufacturer then. Disconnect RIO... same effect. EVERYBODY hates RIO but this is the world we live in now.
What bothers me is that the underlying cause of backover accidents are never discussed. There are things we can do while operating equipment that can really make a difference in PREVENTING backover accidents. You just need to know the underlying cause.
RIO is on mowing equipment now primarily because of successful damages awarded in child backover cases. They are awful. Some are limited to backovers only while others fall into the most severe category: blade contact cases.
One underlying factor that often appears in backover cases is that THE CHILD HAD BEEN GIVEN TRACTOR RIDES. "Big deal.... it is safe. I've got a good hold on her. SHE WON'T FALL OFF" is the typical thought. The issue is that it teaches the child that tractors are
FUN. Here is a typical accident scenario:
- Toddler had routinely been given tractor rides
- Parent is outside mowing while child is inside with supervision
- The child disappears momentarily
- Child approaches the machine from behind wanting another tractor ride
- Operator does not know child is there
This is how it typically goes down. It is more common than you think too. DO NOT GIVE YOUR CHILDREN/GRAND CHILDREN TRACTOR RIDES! My tractors are always put away when grandkids come to visit. Teach your children that tractors can be dangerous and they shouldn't ever approach one without a parent.... you get the idea.
RIO will probably never go away but we can all do things to help prevent backover accidents. Hope this helps!
