Yep, that is my White 7300 combine. Near as I can tell the picture was made in early spring or late winter of 2006 . The ground hasn't been worked yet for the spring planting and the west property line has not yet been cleared.
Yes, the land here is relatively flat to gently rolling. I am between the flat prairie lands west of the Miami river and the hills around Bellefontaine and eastern part of Logan County. There is actually a ski resort 15 miles east of me near East Liberty and the Highest point in Ohio, at 1549' is 10 miles east of me. My elevation is 1120'. I am located at the south end of what was once the ancient Lewistown Lake area, so has very small particle, wave modified clay soil. Very productive, but demands care for proper tillage. Wet spring tillage puddles terribly, so fall tillage works best.
West of the Miami River and all of western and northwestern Ohio is the eastern limits of the prairie lands continuing through all of the corn belt.
