SUMMARY. 
(1) Daily and seasonal working factors for farm labor and equip- 
ment are of primary importance in farm organization and manage- 
ment . 
(2) The seasonal and daily duty of men and equipment for an 
agricultural area can be reliably approximated by averaging many 
estimates for each operation made by farmers in the region. Figures 
so obtained are as accurate for practical purposes as those secured 
by more refined methods. 
(3) Data secured in this manner will yield dependable averages in 
proportion to the experience of those giving the original data and 
to the care with which the estimates are made. They are, then, not 
guesses, but the concrete expression of seasoned judgment. 
(4) Those engaged in farming have quite definite conceptions of 
the duty for the simpler operations where but one or two men and 
one or two teams are involved. 
(5) Where many men and units of equipment are used in an oper- 
ation there is less definite conception of what constitutes a fair day's 
work, since fewer have had experience with the larger crews, and the 
range of variation is greater. More data are therefore necessary to 
insure useful averages. 
(6) With implements of heavy draft and also with many of the 
fighter implements, the increase in dimensions is not attended with 
proportional increases in work accomplished. For this reason the 
widths, sizes, and crews most frequently used are taken as affording 
the most reliable standards, the duty of variations from these being 
calculated by the use of factors included in the tables. 
(7) The increase in the number of men in the crew and in the 
complexity of the operation are attended by lost motion and de- 
crease in efficiency per unit of labor and equipment. The. simpler 
operations are the most economical from the standpoint of work 
done daily.
