Deere 5425 hand throttle problems

Good to know. I always say to look for the lowest common denominator of a problem. Try the easiest thing first and go from there.
Thanks for the update.

That's why I asked if you had ePTO. When shifted to ePTO it not only moves gears inside, but changes the throttle stop on the injection pump, whether you have the PTO engaged or not.
It then limits your rpm to 1700-1800.
