You should probably trade. Then next year when the red one is beating the green because conditions favor the red, you can trade again. I'd like to be your sales person. When can I expect your difference payment?

 Why you would compare rotor speed between deere and cih is something over my head. They're completely difference machines and have completely different settings.

 When the next owner of your red machine fixes it with a thousand dollars, and you hear about it,...........well, when can I expect that difference payment?
