Reaper

technology Maturity 9-11 Next article →

A reaper is a specialized farm implement used to harvest crops. It functions by cutting and often gathering plants when they are ripe. Most commonly, reapers are used on cereal grasses like wheat. This process is vital for food production. Historically, reaping was a manual task involving tools like scythes, sickles, and cradles. Today, mechanical reapers are central to mechanized agriculture. They have significantly increased how much food can be produced.

The mechanism of a mechanical reaper involves several moving parts working in sequence. For example, the McCormick reaper used a main wheel frame that projected to the side. A platform contained a cutter bar with fingers. A knife moved back and forth through these fingers, driven by a crank. A divider sat ahead of the platform to separate the grain to be cut from the standing crop. Above the platform, a reel held the grain against the knife. This action threw the grain back onto the platform for collection.

There are different types of machines used for different plants. A distinction exists between reaping grain and mowing hay. Reaping usually refers to cutting cereal grasses. Mowing refers to cutting greener grasses used for hay. Because cereal straw is stiff and dry, while hay is green, they require different blade types. Some machines are simple reapers that only cut. Others are reaper-binders, which cut and bind grain into sheaves. Modern combine harvesters are the most advanced descendants. They cut, gather, thresh the seeds, and winnow the grain in one operation.

The history of the mechanical reaper is filled with competition and innovation. In the 1830s, several inventors in the United States claimed major breakthroughs. Obed Hussey patented a reaper in 1833 in Baltimore, Maryland. His design was highly efficient. It required only two horses and two people to operate. Around the same time, Cyrus McCormick patented his reaper in 1834. His father, Robert McCormick, had begun the work in Virginia. Cyrus completed the project and claimed to have invented the design as early as 1831.

These inventors faced many challenges during the 19th century. The McCormick reaper did not see mainstream success for about 20 years. This was because it lacked a specific feature found in Hussey's machine. Hussey used a saw-like cutter bar that cut stalks more effectively. It was not until McCormick acquired the rights to this cutter-bar mechanism around 1850 that his machine became truly revolutionary. In 1861, the U.S. Patent Office ruled that Hussey's improvements were the foundation of the industry's success. The heirs of Hussey were even granted monetary compensation.

The impact of these machines on agriculture was massive. By 1896, an estimated 400,000 reaper-binders were harvesting grain. These machines changed the landscape of farming between the 1830s and the 1880s. Some companies, like the Champion Machine Company in Springfield, Ohio, became very successful. Springfield earned the nickname "The Champion City" because of this. Despite the benefits, some farmers were slow to adopt new machines. They were sometimes conservative or feared that machines would take away manual labor jobs. They also worried about rocks and stumps damaging the expensive equipment.

Reaping is part of a larger system of grain processing. After manual reaping, stalks are gathered into sheaves, which are bunches of grain. These sheaves are often leaned against each other to form a stook for drying. Once dry, they are moved to a rick-yard to form a stack or rick. In the British Isles, a grain stack is called a corn rick. Eventually, the grain is threshed to separate the seeds from the straw. After the harvest, people sometimes practice gleaning. This is the act of collecting spilled grain from the field by hand or with animals. This entire cycle ensures that the energy from the plants becomes usable food.
