I've got a 2011 massey 1540. It starts up and runs fine, but as soon as I try to put it in gear it dies. Any ideas? I primed and changed the fuel filter that made no difference. I checked the switch under the seat thinking maybe it was junk and wasnt starting because it didnt think I was on the seat. Im at a loss, I need it and the dealer doesnt open back up til wednesday. And suggestions would be much appreciated.
