I just bought a Z520 JD zero turn from a guy. He said he just had a new engine istalled at a JD dealership.
When I pull the switch to engauge the deck the engine pulsates like the governor is screwed up, the little diagostic light on the ignition panel flashes and the deck shuts of after I go forwards maybe 20 feet at the most.
If you shut the deck off and back on again it repeats this same problem.....engine pulsates.....deck shuts off.
