Well, if it makes any difference, my John Deere seat switch, reverse-blade shut off switch, and ignition key switch were absolute junk. I disabled each and every one of those. I can now mow in reverse, I can now hit a bump and continue mowing, and the key switch no longer randomly shuts off the engine. I love my Deere, But, I've had significant issues through the years. I'd never condemn a machine for minor flaws. I just fix them. I'm more concerned that the major hardware continues to perform.
