Fic. 3.—Variation in number of hours per year tractors were used. 
DRAWBAR WORK. 
The average number of hours the tractors were used for various 
kinds of drawbar work is shown in Table 13. In each area they were 
used more for plowing and listing than for any other kind of work. 
On part of the farms tractors were used for practically every field 
operation except haying and cultivating row crops. ‘They were used 
for drawing corn binders on 3 farms in the southern area, on 7 farms 
in the western area, and on 2 farms in the northern area.
