A pin is an element used in agricultural machinery, especially in tractors, which plays a key role in fastening various components. Its main task is to ensure a stable and safe connection between machine elements, e.g. when mounting agricultural tools, trailers or other equipment. These pins must be made of durable materials, resistant to loads, friction and weather conditions, to ensure long-term use in difficult working conditions in the field. Depending on the needs, pins are available in various sizes and shapes, adapted to the specifics of a given machine and type of equipment.
