CUSTOM WORK. 
One hundred seventy-five of the 354 tractors were used for some 
custom work during the year. As shown in Table 11 such work 
amounted to an average of 48 hours for all tractors, or 98 hours for the 
175. About 23 per cent of the work done by these 175 tractors was 
custom work. For 111 of the 175, custom work amounted to 25 per 
cent or less of the total work done. For 50 it amounted to 26 to 50 
per cent, and for the remaining 14 to over 50 per cent. Eighty-three 
of the 175 did only drawbar work for hire, 72 did only belt work for 
hire, and the remaining 20 did both dr awbar and belt work. 
Table 21 shows the number of tractors used for different kinds of 
drawbar and belt work for hire and the average number of hours per 
_ year they were used. More tractors were used for threshing than for 
any other operation and plowing was next in importance. A some- 
what smaller percentage of the two-plow machines than of the three- 
plow and larger sizes were used for custom work.

TRACTORS USED FOR NEITHER BELT NOR CUSTOM WORK. 
While on the average only 80 per cent of the total work done by 
tractors was drawbar work on the home farm, 115, or 33 per cent, 
of the 354 tractors were used for nothing but this class of work during 
the year. The number which were used for different classes of work 
was as follows: 115 for drawbar work on home farm only; 64 for 
drawbar and belt work on home farm only; 67 for drawbar work on 
home farm and custom work; 108 for drawbar, belt, and custom 
work. 
Forty-six, or 52 per cent, of the two-plow machines did nothing 
but drawbar work on the home farm during the year, while all but 
71, or 27 per cent, of the three-plow and larger sizes were used for 
either belt or custom work. In each area the ] percentage of the two- 
low machines whose use was confined to drawbar work on the home 
Men was considerably greater than of the three-plow and larger 
sizes.
