A round baler is a type of agricultural machine used to compress and package hay, straw, or silage into cylindrical bales. These bales are easier to handle, transport, and store compared to loose material. Round balers work by gathering the crop and rolling it into a tight cylinder, which is then wrapped in twine or netting to keep it secure. Round balers come in various sizes and designs, making them suitable for different farming operations. They are often towed behind tractors and can operate in various field conditions. The efficiency of round balers helps farmers save time and labor during the harvesting process.
