UNIT COST OF EQUIPMENT. 



49 



"Total cost" is the sum of depreciation, repairs, and interest. The 

 lowest and highest acre costs for difl'erent machines are shown, 

 though these are not always included in the average. The "Low" 

 figure is usually for a secondhand machine used on a large acreage 

 or for a long period, while the "High" figure is usually for a new 

 machine given very little use. Extra machines on any farm show 

 a much higher cost than those m ordinary use. The interest charge 

 is the greatest factor in the cost of little-used machinerj^, empha- 

 sizing the advantage of utilizing machines to their maximum capac- 

 ity. All data in Table XV are averages of the entire group of 21 

 farms, and not a mean between individual costs.

Annual cost per 

 machine. 



The wide variation m acre cost of all machinery suggests the neces- 

 sity for considermg the acreage per year as an extremely important 

 factor. For instance, 60 com planters averaged 50.1 acres per year 

 at an acre cost of 8.1 cents; 24, averagmg 63 acres, cost between 4 

 and 8 cents per acre; and 15, averaging 34 acres, cost 10 to 13 cents 

 per acre. This separation of planters into two groups was suggested
