A square baler is a specialized agricultural machine used in the process of harvesting and packaging hay, straw, or other crop residues into compact and manageable rectangular bales. These machines are commonly used on farms to efficiently gather and compress loose crop material into dense and easily transportable bales, making them an essential tool for livestock feed production, storage, and transportation. Square balers come in various sizes and configurations to suit different farming needs, but their primary function is to streamline the process of converting bulk crop material into neatly squared and tightly bound bales for storage or sale.
