TwinePro is the new patented knotter innovation by Case IH available on Large Square balers (LB4 XL series and LB6 HD series). Mounted in a stronger frame to withstand higher plunger loads, and featuring electric knotter fans to keep the units clean, the six TwinePro knotters use a simple system to create a high-strength loop knot, allowing the operator to achieve maximum density with a wide range of twines without the risk of bales bursting.
