Unless I’m doing something wrong. I know the switch is connected to something because when the tractor starts and the gauges do their little sweep and all the warning lights turn on for a second…that stationary pto switch lights up then goes out. But no matter what I do, I can’t make it light up by pushing it. I’ve tried parking brake on, HST in neutral, and a combination of the two. No go. The manual doesn’t explain it, probably in part because the older Mx models didn’t have it.
