About 50 people participated in a tour Thursday morning at J&M Manufacturing in Fort Recovery. Joe Knapke, left, service warranty manager, talks about an auger used inside grain wagons. Started in 1960 by brothers Jerome and Maurice Grieshop, the company primarily makes grain-handling equipment, Knapke said. The first gravity wagon the company built in 1961 held 110 bushels of grain. The largest wagon J&M now makes can hold up to 760 bushels. The business, which employs about 100 people, has expanded almost a dozen times. Thursday's tour was held in response to attendees of monthly Mercer County ag breakfast meetings who said they would like to learn about ag-related businesses, breakfast organizer Nikki Hawk said.
