A baler is a machine used in agriculture and waste management to compress and bundle materials like hay, straw, or recyclables into compact bales. These bales are easier to handle, transport, and store. There are different types of balers, including round balers and square balers, each designed for specific materials and uses. Balers work by gathering loose material and compressing it into a tight bundle, which is then tied with twine or wire. This process helps reduce the volume of the material, making it more efficient for farmers and waste processors. Baled materials can be used for animal feed, bedding, or recycling.
