The average annual cost for repairs on the 2-plow tractors had 
been 3.2 per cent of the first cost of the tractors, and the repairs on 
the 3-plow machines had been 2.2 per cent of their first cost. For 
the 2-plow machines which had been used 39 months or over, i. e., 
had done at least three full years of work at the time of the investi- 
gation, the repairs during the year had amounted to 4.6 per cent of 
the first cost, and for the 3-plow tractors 3.2 per cent. 
Unpaid labor. — In addition to the cash outlay for labor and repairs, 
each farmer was asked the amount of time spent by him or by the 
regular farm labor during the year in repairing the tractor. On an 
average, this labor amounted to 1.8 days for the year, but no sucn 
labor was used on 78 of the 286 tractors. Part of these 78 tractors 
required no repairs during the year and most of the remainder were 
machines whose owners were not capable of doing the repair work. 
The actual number of days used on the different machines is shown 
in Table 35.
