Take watered down juice etc. Thin it out leaves more of the substance (main ingredient) to stretch and sell more that way. The list goes on, those are just tiddle wink examples and not even near good analogies but shows the pattern. In short, as the Deere vendor example points out, others will be quick to give it a try also and if successful by law, set a cap on what a customer's previously owned equipment repairs is going to cost them.
