I have a 1920 that has begun to have intermittent PTO issues. Intermittently, both the front and rear PTOs will disengage simultaneously. The fact that this happens to both PTOs at the same time leads me to believe it is something electrical that they have in common. My first guess was the seat switch or connection. So I jumped out the connector and no improvement. The seat light stays lit and the PTOs will drop out. I can't see both PTO switches getting flaky at the same time,so it seems like it must be something else. I ordered replacement PTO switches just in case, but they aren't even close to the same pin-out or mounting style, so using them to eliminate the existing switches is out. Anyone have any ideas? Thanks in advance.
