TRACTORS AND HORSES IN THE WINTER WHEAT BELT. igs 
Plowing and listing.—Table 14 shows the number of acres plowed 
and listed per farm and the percentage done with tractors. On the 
average 18 acres per farm were plowed in the spring and 140 acres in 
the fall. The spring plowing was usually for spring grain or “sowed 
feed’’ (cane, Sudan grass, etc.), and only a small amount of either of 
these crops was raised on the average farm. (See Table 14). Listing 
was not common in any except the southern area. 
Fall plowing required more power than any other single operation 
-in each area, and the tractors did a larger proportion of this than any 
other operation. On many of the farms the tractors did all of the fall 
plowing and on only a very few farms were horses used for as much 
as 50 per cent of it. (See fig. 4.) 
Fic. 4.—The 3-plow tractoris the most common size used. Tractors are used more for plowing and listing 
than for any other operation.
