King described the procedure for using the Split-Log Drag and specified its benefits in a 1908 Farmers’ Bulletin:
There are at present in this country about 2,000,000 miles of such roads, most of which must be maintained by some means more or less inexpensive. The split-log drag is of great service on roads of this class, and an increasing mileage of the rural highways of this country is being kept in repair economically and well by the use of this simple implement. It is now in use in many States of the Union and in foreign countries also, and its adoption in most localities where there are earth roads will doubtless increase. The aim in writing this bulletin has been to give a concise description of the construction of the split-log drag and the method of using it which will give the best results.
