SIZE OF FARM AND SIZE OF TRACTOR. 



The number of tractors of different sizes on the farms of different 

 sizes (as measured by the number of crop acres) is shown in Table 8.

Seventy- five per cent of the farms vvith less than 160 crop acres 

 were equipped with 2 -plow tractors, and 53 per cent of those with 160 

 or more crop acres were equipped with this size of machine. 



WORKSTOCK ON FARMS OF DIFFERENT SIZES. 



The average number of workstock, the number of days of horse 

 labor per farm, and the number of days' work per head on the farms 

 of different sizes during the year of the investigation are shown in 

 Table 9. The number of days' work per head was obtained by divid- 

 ing the number of days' work on the farm by the number of workstock 

 kept. Each farmer gave the number of hours which are considered 

 a full day's work on his farm both for the workstock and for the 

 tractor, and the average is practically 10 hours for each. 



The number of workstock varied considerably on farms of the same 

 size. Likewise the number of days of horse labor per farm varied 

 considerably, depending upon the acreages and } T ields of the different 

 crops, upon the practices followed in preparing the seed bed, planting,
