Exmark 103-6401-S Notched Blade Lazer Z Vantage Turf Tracer S X Z Series 3 Pack

What It Is

The Exmark 103-6401-S is a genuine OEM notched blade designed for Exmark Lazer Z, Vantage, Turf Tracer, S, X, and Z Series zero-turn mowers. Sold as a 3-pack, these blades are intended for fine-cut grass discharge and bagging, not heavy mulching or rough terrain.

Fitment & Compatibility

Before purchasing, verify your deck size: these blades fit 48-inch, 52-inch, and 60-inch Exmark decks that use a 0.5-inch center hole and a 3.5-inch blade length (measured from center hole to tip). Check your model: Lazer Z (all series), Vantage, Turf Tracer, S, X, and Z Series with notched blade design. Measure your current blade’s length and center hole diameter—aftermarket blades may vary. Confirm your deck uses three blades (not two). If you have a different brand (e.g., Toro, John Deere), these won’t fit without adapter kits.

Key Things to Know

• Installation difficulty: Easy for DIY—use a blade removal tool and torque to 70-90 ft-lbs. Loosen the nut, not the blade bolt.
• Common gotcha: Notched blades reduce lift compared to standard high-lift blades; expect less bagging efficiency in wet grass. Avoid using them for heavy mulching—they’ll clog.
• Quality: Genuine Exmark steel, heat-treated for durability. Aftermarket copies may dull faster or warp.
• Sharpening: Can be sharpened once or twice, but replace if nicked or bent. The notches weaken the blade edge over time.

Should You Buy It

If you own an Exmark zero-turn with a notched blade deck and want OEM reliability for fine, manicured lawns, this 3-pack is a solid buy. It’s not for heavy-duty mulching or rough mowing—stick to standard blades for that. For bagging or discharge on dry grass, it delivers clean cuts and consistent performance.
