Reaper-binder

technology Maturity 11-13 Next article →

A reaper-binder is a helpful farm tool.

It does more than a simple reaper. A reaper only cuts the grain. A binder cuts the crop and ties it. It makes bundles called sheaves. These sheaves help farmers harvest grain. This tool changed how people grow food.

How does this machine work? First, a reel and a sickle bar move. The sickle bar cuts the grain stems. The cut stems fall onto a canvas bed. This bed moves the stems along. Then, a binding mechanism gathers them. It ties the stems with string. The machine then drops the sheaf out the side.

People worked hard to improve this machine. Charles Baxter Withington invented the binder in 1872. He was a jeweler from Janesville, Wisconsin. His first binder used wire to tie bundles. Later, William Deering made a better version. His machine used twine instead of wire. It used a knotter to tie the string. John Appleby had invented the knotter in 1858.

Early binders were pulled by horses. They used a bull-wheel to get power. The pulling motion created a spinning force. This force ran the mechanical parts. Later models were pulled by tractors. Some even used a power take-off, or PTO. A PTO is a device that transfers power. In Poland, binders were used very often. But farmers sometimes lacked twine or parts.

Farmers often stack sheaves into stooks. Stooks are A-shaped piles. They look like small tipis. These piles let the grain dry for days. Today, many farmers use a combine harvester. A combine does many jobs at once. Still, binders are useful in some places. They work well in small fields. They also work in steep mountains.
