My 2380 was bought new, has about 150 hrs and has been trouble free. I drove into the woods to cut some trees and everything worked until I pulled in the shop to shut it off. It just kept running. I manually shut the fuel solenoid off. I tested the solenoid, the timer relay. and every fuse. All were fine. That leaves the OPC which is in a nearly impossible place to reach. I think that will probably be OK, but have not tested it. Is there anything under the tractor that I might have messed up driving over small 1/2" saplings? Other suggestions? I am about ready to give up and just use a wire to connect to the solenoid and into the cab to manually shut down the tractor. 3Three days fooling with it is enough.
