FARM MOTOR TRUCK OPERATION. 3 
A majority of the owners estimated that their trucks were used on 
an average of 147 days, and traveled slightly over 3,100 miles in the 
year preceding their report. 
The expense of operation per mile run (see p. 23) varied from 
7.8 cents for the half -ton machines to 20.7 cents for the 2-ton size. 
The cost per ton-mile for hauling crops (see p. 24) ranged from 37.3 
cents for the smaller trucks to 15.8 cents for the larger size. 
Over two-thirds of the owners reporting stated their machines had 
always been ready for use when needed during the preceding year. 
The addition of motor trucks to the farm equipment had displaced 
on the average less than one horse for each machine purchased.

Three hundred and eighty-six replies to the 1922 questionnaire

Of the 386 men reporting, 325, or 84 per cent, owned the same 
motor trucks upon which they reported in 1920, and stated they Avere 
still using them. 
Of the 61 men who no longer owned the machines covered by the 
earlier reports, 50 had replaced them with others, while 11 trucks had 
not been replaced. 
TYPES OF FARMS ON WHICH TRUCKS ARE OWNED. 
The farms operated by the 325 men who stated they used their old 
trucks are of various types and sizes, ranging from truck farms con- 
taining in some instances but a few acres to large dairy farms of 
several hundred acres. They have been classified according to the 
type of farming practiced as fruit, dairy, truck, crop, and general 
farms. On those classed as fruit farms, fruit is the principal source
