A thresher is a machine used in agriculture to separate grains from their stalks and husks. This process, known as threshing, is essential for harvesting crops like wheat, barley, and rice. Threshers can be powered by engines or operated manually, and they help increase efficiency in the farming process. Modern threshers often combine multiple functions, including cutting and cleaning the grain. They are an important part of the harvesting process, allowing farmers to process large amounts of crops quickly. The use of threshers has significantly improved productivity in the agriculture industry over the years.
