These replacement blades are genuine EGO parts made to match the performance standards of the Z6 ZTR 42" riding mower. Designed from durable steel and shaped to deliver a consistent, clean cut, the AB4200D set helps maintain lawn appearance and mower efficiency when fitted correctly.

How will these blades affect lawn cut quality?

Replacing dull or damaged blades with the EGO AB4200D set restores edge sharpness and even grass discharge, resulting in a neater finish. Sharper blades slice grass cleanly rather than tearing it, which improves visual uniformity across the lawn.
