A square baler is a type of agricultural machine 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 bales produced by square balers can vary in size, typically ranging from small to large, depending on the model. Farmers often use these bales for livestock feed or bedding, making square balers an essential tool in modern farming practices.
