The Exmark 103-6393-S is a genuine OEM 20.5-inch mulching blade designed for compatible Exmark 60-inch mower decks. It features a 15/16-inch center hole and a high-lift cutting profile that keeps grass clippings circulating through the cutting chamber for additional reduction.

High-Lift Mulching Performance
The blade’s high-lift profile creates the airflow needed to keep grass clippings suspended beneath the deck. This allows the blade to cut the material repeatedly before directing the smaller clippings back into the lawn, reducing visible debris and post-mowing cleanup.
For best results, sharpen the blade as needed and inspect it regularly for excessive wear, cracks, bends, or deep nicks. A damaged or unbalanced blade can reduce cut quality, create vibration, and place unnecessary stress on spindle assemblies and other mower-deck components.
Why Choose Genuine Exmark OEM Mulching Blades?
Genuine Exmark blades are engineered to provide the correct length, center-hole size, cutting profile, balance, and deck clearance for compatible Exmark equipment. Using the specified OEM blade helps maintain the airflow and clipping-reduction performance intended for the mower deck.
Important: Verify your model, serial number, 60-inch deck configuration, center-hole size, and required blade quantity before ordering. Exmark frequently uses different blades across similar mower models and deck configurations, and fitment can vary by serial number.
