Machine Cost of Using Power Sprayers 



On an average, power sprayers were used the greatest number of hours 

 per season, in Arkansas, or 176 hours, and the least number in Michigan, or 

 76 hours* (table 74.) 



Orowers inventoried their sprayers at the end of 1928 at an average 

 of ;^264 in Pennsylvania and $210 in Michi^n. The average cost of operat-

 Gas and oil expense was a small part of the cost, varying from an average 

 of §5 per prayer for Michigiin to §14 for Arkansas ♦ Depreciation was the 

 largest cost item and varied from an average of $29 per machine for Michi^n 

 to $41 for Pennsylvania •

On an average, depreciation costs decreased as the age of the sprayer 

 increased. The depreciation during the first or second year the sprayer 

 was used averagedabout $75 per season. About half as much, or $37, Fas the 

 yearly depreciation of sprayers that had been used six seasons. In 1928, 

 depreciation averaged only $18 for machines bought before 1922. (table 75.)
