The combine will randomally come to a stop while thrashing with orerator in seat. stoped one time while driving on the hiway and could not move for an half hour. dealership trys to blame it all on the seat switch. we still have the problem so they wanted to convert them back to a cable to the hydro and they dont stop any more but they still disengage the seaprator on there own and will not re engage sometimes for quite a while after multiple restarts. has any one had this kind of truble with a 2009 9670 sts equiped with auto harvest.
