iMany owners reported the total repairs, but did not give them by years. This column is the average 
of all reports of total repairs, and therefore does not agree exactly with the sum of the annual repairs. 
It will also be noticed that the successful owners use their tractor 
more days annually than do the unsuccessful owners, which w r ould 
naturally be expected in view of the smaller number of horses kept 
by the former class of men. 
The causes underlying the difference in results obtained are many 
and various. While much of the difference can be traced to the 
owner or operator, other important factors are involved, and some 
of these will be shown in the tables that follow.
