SIZE AND AGE OF TRACTORS. 
The number of tractors of different sizes in use in the different 
areas and the average size 1n crop acres of the farms on which they were 
used, are shown in Table 6. The tractors are classified according to 
the number of 14-inch moldboard plows pulled. The three-plow 
size predominated in each area. In general the larger tractors were 
found on the larger farms.

The number of tractors which at the time of the investigation had 
been in use for different lengths of time is shown in Table 7. A 
considerably larger percentage of the tractors in the Western area 
than in the other areas had been in use just one year. This was in 
the main due to the fact that the wheat crop of 1920 was good. The 
crops of 1918 and 1919 had been poor and few farmers kad purchased 
tractors in those years.
