 I don't know about all the companies, and of course I'm not inside on John Deere's, but I think they learned a big lesson in the 1980s because they kept manufacturing and manufacturing as prices fell. He tells Brownfield that hurt Deere's bottom line, and now margins are thinning for many farmers. When you're losing $50 or $60 an acre, farmers aren't going to have the money to spend on new machinery like they did.
