BULLETIN 3, U. S. DEPARTMENT OF AGRICULTURE. 
high-wheeled type increase the daily efficiency of the implement 
from 40 to 90 per cent, making this equipment nearly as efficient as 
the 2-row planter with two horses. On the 2-row planter it is, of 
course, necessary to take considerable time in changing the check 
wire. The 2-row planter with two horses is essentially twice as rapid 
as the 1-row planter with one horse. With an inexpensive hand 
planter a man can plant from 60 to 75 per cent as much corn as can be 
done with a man and one horse using the horse-drawn type of imple- 
ment.

Work factors for planting sweet potatoes, cabbage, and tomatoes 
by hand are arranged by crews in Table XIII. On account of the 
limited data for each crop, the data for the three crops are averaged 
in the table. Planting sweet potatoes can be done somewhat more 
rapidly than planting cabbage, while tomatoes can be set out some- 
what more rapidly than sweet potatoes. The duty of a man at 
work of this character is not less than 0.75 acre per day. Compara- 
tive data for planting these crops with a transplanting machine were 
not made available because of the limited number reporting trans- 
planters.

In Table XIV are presented the averages for cutting seed potatoes 
by hand and with the mechanical cutter, respectively. The cutter 
does the work somewhat more than 100 per cent faster than it can
