Good luck going through Deere. I've searched all through JD Parts and cannot find any reference to HR1-5E. That is the main complaint I have with the JD branded OEM equipment. They are great for parts on tractors and implements but on equipment like generators, pressure washers, snow blowers, etc. they are terrible. If the Deere parts guy doesn't come through I would try to find out who the original manufacturer was and the model and then try to contact them for parts.
