Versatile Cutting Performance
The Exmark 103-6402-S is designed as a versatile standard blade for approximately 80% of common grass conditions. Its notched high-lift profile creates airflow beneath the mower deck to raise grass into the cutting path and move clippings efficiently through the discharge opening or into a compatible collection system.
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 the spindle assemblies and other deck components.
Why Choose Genuine Exmark OEM 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 proper airflow, cutting quality, and safe mower-deck operation.
Important: Verify your model, serial number, deck size, 15/16-inch center hole, 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.
