The AG Belt Heavy Duty Diamond Top X Smooth baler belts are built for heavy-duty baling, particularly in high-tension balers handling demanding crops like cornstalks and silage. These premium belts feature a heavy-duty fabric blend of polyester and nylon outer plies with a full polyester center ply, ensuring superior fastener retention, tear resistance, puncture resistance, and exceptional longevity. Manufactured using a rotary curing process, these belts deliver consistent, high-quality performance across the entire belt. The P521 version includes a smooth bottom cover, making it an ideal replacement for newer John Deere models. For added durability and reliability, these belts come equipped with Mato High Performance Fasteners, chosen by many round hay baler manufacturers for their outstanding strength and long splice life. All fasteners are professionally installed using OEM production equipment, ensuring a superior and long-lasting connection. Each belt purchase includes the connecting pin for your convenience.
