A new tractor dealership plans to open Monday in a Gainesville building that used to be a car dealership. Ag-Pro, which is a John Deere dealer, will be moving into a Browns Bridge Road building that was once part of Carriage Kia and before that was a Carriage Mitsubishi dealership. Luke Clark, general manager of the Gainesville Ag-Pro location, said the Boston, Ga.-based company will be up to 47 locations by March.
