) As the cultivation of grain developed, the seasonal harvest became a major agricultural event. Grain could be pulled or, later, cut with a
sickle and tied into
sheaves to be
threshed. The scythe improved on the sickle by giving the mower a more
ergonomic stance and permitting a larger blade. However, keeping the grain stems aligned in the
windrow required great skill and where these skills were less available the addition of a cradle helped to manage the grain heads, reducing the
sheaver's work-load and improving efficiency at
threshing. Lesser skilled mowers could harvest significantly more grain by using the cradle. Although the grain cradle was in previous use in parts of Europe it was not generally used because skilled labour was traditionally available. Between 1800 and 1840 the cradle was widely adopted in the expanding grain growing area of
Midwestern United States, undergoing some refinement there and resulting in the American-pattern cradle. Fifty American
patents were issued between 1823 and 1930, the first in 1823 in western New York state and the last in 1924 in West Virginia peaking between 1875 and 1900. {{cite book Hay does not require aligning and the scythe is more efficient without a cradle, so it was removed for haymaking. ==Decline==
