CHANGE IN TILLAGE PRACTICE. 
These farmers were asked the same questions concerning their 
tillage practices as were the tractor owners. It was found, however, 
that only 4 of the entire 85 were making it a practice to plow a 
greater percentage of their land, plow deeper, or do better seed-bed 
preparation other than plowing in 1921 than in 1918. 
OPINIONS CONCERNING TRACTORS. 
To determine the attitude of men who do not own tractors toward 
their use, each man was asked why he did not own a tractor, and — 
if he intended to buy one in the future. Of the 85 men, 23 stated — 
definitely that they expected to buy tractors in the future, 11 were 
undecided, and 51 said that they intended to continue farming with ~ 
horses only. Ten of the 85 men had previously owned tractors but 
had disposed of them, chiefly because they were considered more 
expensive than horses. 
As a reason for not owns tractor, the first cost or cost of operat- — 
ing the machine was given by 42 of the 85 men. Some of these 42 
stated that the lack of capital alone had prevented their purchasing 
machines. Sixteen of the men thought the tractors would not be 
4 
paying investments and 8 considered themselves mechanically in- | 
competent to operate tractors. 
COST OF POWER AND MAN LABOR FOR DIFFERENT OPERATIONS. 
The average costs per acre of power, and of power and man labor, 
for the different field operations when done with tractors and horses 
are shown in. Table 66 both for the farms where tractors were owned 
and those where tractors were not owned. Costs for operations per- 
formed by less than 20 men are omitted.
