TRACTORS AND HORSES IN THE WINTER WHEAT BELT. 13. 
Harrows are used but little in the western area. In the southern 
area tractors were used on 68 per cent of the acreage harrowed during 
the year, and in the northern area on only 21 per cent. 
| In addition to the work shown in the table, tractors were used for 
— disking in combination, that is drawing disks and drills or disks and 
harrows simultaneously on 42 acres per farm in the southern area, 
16 acres in the western area, and 1 acre in the northern area. 
Drilling grain and planting row crops.—The acres of grain drilled 
and of row crops planted per farm and the proportion of the acreages 
covered with tractors are shown in Table 16. The acreages covered 
with drills in combination with disks are not included. In the 
northern area a considerable part of the wheat was drilled between 
the rows of standing corn with one-horse drills (see p. 5), and this 
accounts, at least in part, for the greater use of horses for drilling 
in that area. Drawing a combined lister and drill when planting 
corn and other row crops is a rather heavy operation, four horses 
ordinarily being used on a one-row implement, but on the average 
only 17 per cent of this work was done with tractors.

1 Less than 0.5 acre. 
Harvesting.—The acreage of wheat and other small grain harvested 
with binders, headers, and combines, and the percentage done with 
tractors are shown in Table 17. In the southern and northern areas 
the greater part of the crop was harvested with binders, but in the 
western area over 85 per cent was harvested either with the header 
or combine. In each area tractors were used on a little more than 
half of the acreage cut with binders; they were always used for 
drawing the combine, but horses were ordinarily used for the headers. 
(See figs. 5 and 6.) 
On nearly every farm where the tractor was used for drawing any 
one of these three machines a man was used on the machine as well 
as on the tractor; that is, one man more than would have been used 
if horses had furnished the power. In most cases where headers 
and combines were used horses drew the header barges and the 
rain wagons for the combines. In some cases, however, com- 
ination hitches were used and the entire outfit was drawn by the 
tractor. :
