Table VIII gives the crews and duty of machinery as the average 
on 38 farms for seeding and harvesting timothy and clover. The 
figures given for broadcasting with a wheelbarrow seeder are for 
using the seeder one way. Where one-half of the seed is drilled in 
one direction and one-half broadcasted in a cross direction, simply 
add the work units for seeding with drill and seeding with a wheel- 
barrow seeder. 
Very few mowing machines wider than a 5-foot cut are used for 
the ordinary hay crop. The tedder is usually used for clover or for 
heavy timothy and mixed grasses. Both the dump and side-delivery 
rakes are used, but the latter is generally preferred. This implement 
is especially necessary if the hay is loaded with a loader from the 
windrow. The side-delivery rake will, furthermore, quite largely 
take the place of the tedder. The figures given for loading, hauling, 
and storing are based on pitching in the fields by hand and un- 
loading in the barn with a horse fork or sling. Insufficient data 
were obtained on the use of a hay loader, but there is little doubt 
that in favorable weather the hay loader would be of decided advan- 
tage, particularly with timothy or mixed grasses. 
Table IX gives the crews and duty of machinery as the average on 
18 farms in seeding and harvesting alfalfa. Alfalfa is a compara- 
tively new crop in Chester County, but a few successful growers 
were interviewed, from whom data were obtained. Inoculation has 
been done by applying soil from an old alfalfa field at the rate of 
300 or more pounds per acre. Recently commercial cultures have 
been introduced. While the cost of these cultures usually exceeds 
the cost of applying soil, the convenience of handling is an important
