This article was originally published as a TechRepublic cover story. Marcus Hall was nine years old when he first drove a tractor on his family's sprawling Iowa farm, eschewing Tonka trucks and Matchbox cars for long rides on heavy machinery. Growing up on a multigenerational family farm is common in an agricultural state like Iowa, where nearly 27 million acres are devoted to cropland--out of the 35 million acres that make up the state. Hall grew up with all the trappings of a future farmer, but a penchant for technology led him down a more experimental path--to the test farm of ag equipment giant John Deere. As manager of the test farm, Hall gets to run field trials of John Deere's high-tech farm equipment before it goes to market. "I just enjoy being out on the tractor," says Hall. "Plus, it's fun being part of this type of technology and the leading edge of what's out there." Download this article as a PDF (free registration required). It's a warm, breezy day in late May 2018, when we meet up with Hall at John Deere's test facility in Bondurant, IA. The farm sits on an unassuming patch of land framed by two-lane roads.
