A Riverside man has won 200 Hour Tractor. Steve Prybil of Riverside won a 200-hour John Deere 8320R tractor lease from The Iowa Soybean Association (ISA) in its Opportunity Sweepstakes on Thursday. Prybil also won $1,500 worth of soy biodiesel to fuel the tractors. Almost 2,000 Iowa soybean farmers registered for the chance to win a tractor lease either online or at this year’s Farm Progress Show in Boone. Prybil says he never signs up for “these kind of things” but was urged to by a friend. Along with registering for the possibility of a new tractor, everyone who signed up became a member of the ISA, which offers numerous benefits, such as a subscription to “Agri-Pulse,” and other magazines.
