• Aramid Cords That Hold Their Shape Under Load: Built around aramid tensile cords the same fiber family used in industrial drive applications. Resists stretching and absorbs shock loads when the blades hit thick grass, sticks or roots, so the belt holds its tension instead of slipping or snapping.
• Steady, Slip-Free Power From the First Cut to the Last: Engineered for consistent performance whether youre mowing a half-acre or a full commercial property. Excellent dimensional stability and low thermal shrinkage keep the belt true to spec under heat, so power transfer stays smooth and predictable as the mower warms up.
• A CR-Treated Jacket for a Longer Service Life: Sized for long operating hours and demanding workloads. An optimized rubber core keeps vibration low while the CR-treated outer jacket resists abrasion, moisture and debris the three things that wear deck belts out fastest for a longer service life and fewer mid-season replacements.
