Exmark 103-6402-S Notched Blade Lazer Z Pioneer Vantage Turf Tracer Metro 3 Pack

What It Is

This is a set of three OEM Exmark notched blades (part 103-6402-S) designed for high-discharge cutting decks on Exmark zero-turn mowers. They’re built for mulching and bagging performance, not standard side-discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch or 52-inch deck. This specific blade fits Exmark Lazer Z, Lazer Z X-Series, Pioneer, Vantage, Turf Tracer, and Metro models with those deck sizes. Check your deck’s blade-mounting hole: it uses a 5/8-inch center hole and measures 18.5 inches long. If your mower is a different brand (e.g., Toro, John Deere), these will not fit. Always verify your model number against Exmark’s OEM parts list or measure your existing blade length and hole size.

Key Things to Know

• Notched design improves mulching and bagging by creating more lift and a finer clip, but reduces side-discharge efficiency.
• OEM quality means exact fit and balanced out of the box; aftermarket alternatives may be cheaper but can cause vibration or poor cut.
• Installation requires a torque wrench (set to 70-90 ft-lbs) and a blade removal tool. Reverse threads on some Exmark spindles are rare, but check yours.
• Sharpening is possible, but the notch makes it trickier; many users replace rather than sharpen.

Should You Buy It

If you own a compatible Exmark zero-turn with a 48 or 52-inch deck and prioritize mulching or bagging over side-discharge, this three-pack is a solid investment. The OEM fit and high rating justify the price for users who want zero hassle and consistent cut quality. For side-discharge-only users, consider straight blades instead.
