New guy with a 2014 L3901 (300 hours). I ran over a branch that bounced up and sheared the 2 wires off of a switch underneath the chassis about where the brake pedal is located. It's a boxy little switch that is adjustable. Tractor immediately stopped running, throws error E20 (if I remember correctly).
Q: What is that switch called, what does that switch do, and how can I fix it? And, how can I clear the code error?
Thanks!!

Yes, mostly. What apparently happened when the branch severed the wiring, it shorted the ECU and popped the fuse. I replaced the fuse and removed the switch so I can repair/replace it. Everything works fine now though.
