The Iowa Agriculturist
After a farmer had planted seeds, the battle against the weeds began.
For years hand-power was used to cultivate the land to wipe out seeds.
To do this, farmers used hoes usually made of iron by the village blacksmith.
Corn farmers usually needed to hoe their crops four times each season.
At the rate of ¾ to one acre per day, as much as six days labor per acre
might be spent killing weeds.
Soon inventors helped farmers cultivate. In about 1820 farmers
were using single-row horse-drawn equipment. Its purpose was to loosen
the soil and kill weeds. Various types of cultivators quickly followed.
Some used the "shovel-plow" which fit easily between corn rows, killed
the weeds, stirred the soil, and tilled the plants by throwing more earth
around the newly sprouted corn. In fact, the shovel plow remained the
common cultivating tool until the 1850's in Iowa and Illinois.
By the late 1860's, horse-drawn two-row cultivators with
a seat for the farmer, also called a sulky, were being used in the Midwest.
