A square baler is a type of agricultural machinery used to compress and package cut grass, hay, or straw into compact rectangular bales. These bales are easier to handle, transport, and store compared to loose material. Square balers can be towed behind tractors and are designed to work efficiently in various field conditions. The process involves feeding the cut material into the baler, where it is compressed and tied with twine or wire. Once the bale is formed, it is ejected from the machine. This equipment is essential for farmers who need to manage large quantities of forage for livestock, making it a vital tool in modern agriculture.
