This displacement of horses by motor trucks is quite comparable 
to the displacement by tractors in this section. A study of 252 New 
York farms on which tractors are owned, as reported in Farmers' 
Bulletin 1004, "The Gas Tractor in Eastern Farming," showed that 
on these farms the total work stock owned when the tractors were 
purchased amounted to 1,321, while the total after the purchase of 
tractors was 1,018, a reduction of 22 per cent, and an average dis- 
placement of 1.2 head per tractor. 
FARMS ON WHICH TRACTORS ARE OWNED. 
Of 675 men who reported on whether or not they own tractors, 180, 
or 27 per cent, stated that they own tractors. Tractors are owned 
on a larger percentage of the crop and fruit farms than on farms of 
other types. They are owned on 9 per cent of the truck farms, 33 
per cent of the dairy farms, 38 per cent of the fruit farms, 42 per cent 
of the crop farms, and 25 per cent of the general farms. Size of the 
farm, however, evidently had a greater influence in this regard than 
did the type of farming. The number of men with farms of different 
sizes (crop acres, not total acres), who do and do not own tractors, is 
as follows: 
Of 243 men with 60 or less crop-acres — 
21 own tractors. 
222 do not own tractors. 
Of 227 men with 61 to 120 crop-acres — 
47 own tractors. 
180 do not own tractors. 
Of 103 men with 121 to 180 crop-acres — 
42 own tractors. 
61 do not own tractors.
