Petersen Grain Farms of Marengo, Illinois was having a lot of problems with standard tires. Traction, air pressure, power hop and road lope were all issues they were experiencing on their John Deere equipment.  They upgraded to Low Sidewall Technology® (LSW®) tires and haven’t looked back. After nearly a decade of heavy use – the tires and tractor are performing significantly better than when the machine was purchased new.
