Calvin had seen the cooperative save a harvest when one family lost its combine two days before a storm. He had also seen bad decisions at the central office ripple across fifty farms like a weather system no one could escape. The responsibility was never abstract to him, because he knew the people who would pay if his figures proved wrong.
When he looked at the proposed John Deere order that winter, he saw several genuine advantages. New machines would offer more consistent power, reduced fuel consumption in many tasks, modern guidance systems, comfortable cabs, improved operator visibility, and warranties on components that had become expensive on the existing fleet. Those benefits belonged in the calculation, and he refused to erase them merely because Norm had introduced a competing risk. Frank Odell's desire for new equipment was not foolish; Frank spent his days managing breakdowns and had the bruises and grease-stained notebooks to explain why he wanted a fresh start. A model that made new machinery look bad by pretending old machinery never failed would have been worse than no model at all.
Calvin therefore began with a list of everything that could go wrong on the older fleet. He asked Frank for five years of repair invoices, hour-meter readings, documented outages, fuel records, and labor charges. He separated planned maintenance from unexpected failures, then separated unexpected failures by whether they actually stopped work during critical windows. A hydraulic hose replaced on a rainy afternoon was not the same cost as a failed transmission on the last suitable harvest day. He assigned each event a reasonable range of consequences rather than inventing one precise future and calling it certainty.
His first model favored the new purchase by a modest margin. That was discouraging for about two minutes, and then he realized he had made an error in how he counted service access. He had entered the authorized labor rate but not the number of days that might be lost waiting for a dealer-controlled diagnostic function during the busiest weeks. He had also treated all breakdowns as if the cooperative could choose any qualified mechanic available, an assumption that might not survive the software transition Norm described. When he corrected those limitations, the result changed, though not as dramatically as Norm's most alarming estimate suggested.
Rather than settle for the version that supported his concern, Calvin created three cases. One assumed that diagnostic access stayed widely available and authorized dealer rates rose only slightly faster than ordinary inflation. The second assumed that some important functions became dealer-dependent and rates increased within the range Norm considered likely. The third assumed a more restrictive transition, larger rate increases, and longer service queues during peak seasons. Calvin discovered that the existing fleet could remain competitive in the middle and high-cost cases if it was refurbished properly, but that the new purchase remained attractive if the software limitations never became significant. That uncertainty became the central question of his next fourteen months.
