Very sorry to hear that. Hopefully it's just a loose connection at the pto switch. Could it have anything to do with the safety switches? Hope they get it figured out for you quickly.
They figured out it is the "new" wiring harness that they had already replaced. So, they are ordering another one from LS tomorrow and hope that it comes soon. Apparently LS initially sent out the wrong harness and they had to send it back. Then they got this one that doesn't work properly.
While I believe RCO will do all they can to try and fix this tractor, I don't have faith in LS to do much. Apparently, RCO had tried to get LS to extend my warranty, given the problems I've had since day one, but LS told them too bad and that they should have tried to fix it during the two year bumper to bumper.
So, RCO may be eating some of the costs here, if not parts definitely labor. If anyone should be eating anything it should be LS. But I don't think they care that I bought a crappy product.
