MACHINERY COST OF FARM OPERATIONS. 3 



In Table I is summarized the average service and cost of the 

 principal implements used in western New York. The annual service 

 obtained is expressed in acres and in days. The total service rendered 

 is expressed hi years, days, and acres. The average cost of each 

 implement is shown, and the machinery cost per acre, comprising 

 depreciation, interest, and repairs, is set out for each implement. 



In referring to the cost per acre covered, as shown in this table, 

 it should be borne in mind that these figures are averages and that 

 they do not show the very important bearing which variation in the 

 acreage covered annually has upon the cost per acre of using a 

 machine. This relation is brought out strikingly in the tables that 

 follow. For example, it will be shown that where a mower covers 

 but 13.8 acres annually it costs the owner 36 cents per acre, while 

 the mower that covers 53.6 acres annually costs but 10 cents per 

 acre cut.

SCOPE OF INQUIRY. 



Under actual conditions on the farm there are other factors than 

 use which affect the service obtained from farm machinery. These 

 are (1) exposure to the weather, (2) care in operation, and (3) design 

 and material used in the construction of the implements. No 

 attempt was made in this inquiry to determine the relative influence 

 of exposure, care, and design on the total service rendered by farm 

 implements The sole purpose was to determine how much service 

 standard farm machinery gives in western New York under the aver- 

 age of the conditions existing there. No mechanical or engineering 

 features were considered.
