International Harvester Fertilizer Distributor
from issue: 40-3
Because of the many varieties and mixtures of fertilizer, it is impossible to give complete tables listing them. It is, however, very easy to determine the distribution of any particular fertilizer by proceeding as follows. Put a cloth, or some large sheets of paper under the machine and turn the main driving wheel 57 times for 7′, 51 times for 8′ and 46 times for 9′ machine. Weigh the amount ejected which will indicate the amount distributed per one-tenth of an acre.
