Precision Blade Overlap: On the AG series the blades are staggered precisely with no gap in the mowing area. Blade overlap is important to achieve an even cutting result.

Rotor Rotation - Reverse: The rotor spins in the opposite direction as the wheels of the tractor when traveling forward. This allows the blades to shear the material as it is folded forward by the mowers. The material is then thrown up and over the rotor.

Balanced Rotor Tube: The rotor tube is balanced to reduce vibration and ensures that the mower runs smooth, and reduces wear on the bearings.
