The split log drag used two parallel logs with the cut side of each facing front, separated three feet by rigid separators and pulled by a team of horses, or a truck.
Variations are still in use on baseball infields.
The first log would remove clods and the second would smooth the dirt road. The logs were staggered so dirt would be pushed to the center to create a crown so water would run off.
This made it possible for farmers to improve roads in front of their property (as the DeKalb County article wanted them to do) and not have to wait for government graders.
D. Ward King got a patent for it in 1908, but didn't try to collect royalties on it.
