WORK DONE WITH TRACTORS. 
On the average tractors were used for 376 hours during the year. 
Drawbar work on the home farm consumed 302 hours, or 80 per 
cent of the total; belt work on the home farm, 26 hours, or 7 per 
cent of the total; and custom work the remainder. The number of 
hours of drawbar work performed was least in the northern area, 
and likewise the proportion of the total drawbar work done with 
tractors was considerably less than in the other areas. (See Table 
25.)
