One reason for buying JD green is that they usually take care of their errors, especially if it is a large (meaning lots of $$$) customer. I once received an internal Deere video talking about the cost of poor quality with poor quality meaning errors in design along with manufacture. A few years after I started my engineering career I started listening to some friends at work who were interviewing and getting offers for considerably more money than we were making. I interviewed with one of the companies a friend had rejected, a short line farm equipment manufacturer. In designing a manure spreader, their test program was renting a tractor from a farmer near the plant, loading the spreader with sand, and driving up and down a local gravel road for a week. If it crack, they patched. If it lasted, it went into production. Deere spends a higher percentage of sales on design and development than any other major farm equipment manufacturer, but the people there are still human and they screw up, but they do go out of their way to keep the screw ups as their pain, not the customer's. A customer does feel better if somebody from the corporation shows concern, especially if they bring caps.
