In the above summary of costs the overhead charges on the 

 prime mover are included in the various costs of operation. 

 Machinery costs for the tractor are a trifle higher, because 

 of the added investment in suitable plows. 



The manager of a noted Dakota bonanza farm puts his cost 

 of raising wheat with horses at $8.45, a figure which is lower 

 than the average recently reported for that section by the 

 United States Crop Reporter. A traction farmer only recently 

 produced a 2000-acre crop of flax in the same section for 

 $6.56 per acre, allowing for all overhead charges on engine, 

 machinery and land. Roughly speaking, the gas tractor cuts 

 10 cents per bushel from the cost of producing an acre of 

 twenty-bushel wheat.
