Old tech guy has old tech stuff he spends a lot of money on to keep running. He is not old tech by choice - raised a family, loans that never get paid off, now partners with his son who is raising a family. Has a hired hand who can keep things going by whatever means possible. New tech guy is anti-new tech but has no mechanical ability, is a bachelor who inherited his farm from his dad, and has never had a loan in his life. He has new tech because he can't fix it if it breaks down so he buys new frequently - tractors anyway. Then he bums free mechanic help, like me, when something breaks. Anyway being in the middle I get to run all of the tractors and see how much fuel is being sucked down. I ran the numbers for the guy running the old tractors. He could have saved $5,000 on last year's fuel bill if he had the tractors of the other guy but that kind of savings won't justify replacing one, let alone all 13, of his tractors. As for me, if I realized how much more my indirect injected Kubota uses over its direct injected competitor, it may have made me do some more number crunching although I still would have bought the Kubota.
