This John Deere 5020 pulled 320.865 feet to finish second in the Columbus Diesel Light-Limited Pro Stock Tractor class of the OSTPA event Friday evening at the Crawford County Fair. The tractor is owned by Jerry Martin of Bucyrus, but was driven by crew chief Mark Knapp because Martin had arthroscopic back surgery Friday morning. The tractor won the OSTPA event last week in Logan. Photo by Don Tudor.
