Exmark 103-6402-S Notched Blade Turf Tracer HP Vantage Metro Staris E S Series 2 Pack

What It Is

The Exmark 103-6402-S is a notched, high-lift replacement blade designed specifically for Exmark’s Turf Tracer, HP, Vantage, Metro, Staris, E, and S series walk-behind mowers. It’s used for fine-cut, bagging, and high-performance discharge on residential and commercial turf.

Fitment & Compatibility

Before buying, verify your deck size: this blade fits 36″ and 48″ Exmark walk-behind decks listed in the series names above. Measure your current blade’s center hole diameter (must be 7/8″), blade length (16.5″ tip-to-tip), and notch pattern. Check that your spindle assembly uses a single-bolt mounting system (most Exmark models do). Aftermarket blades may differ in thickness or balance; this is OEM Exmark, so no modification needed. Double-check your model number on Exmark’s site or your manual—this blade will not fit zero-turn mowers or larger stand-on units.

Key Things to Know

• Quality & Durability: OEM Exmark steel is heat-treated for longer edge life; notched design reduces vibration and improves lift for dense grass.
• Installation: Simple bolt-on replacement—torque spindle nut to 55–65 ft-lbs. Use a thread locker (e.g., Loctite) to prevent loosening.
• Common Gotcha: Notched blades require correct orientation (notch faces up toward deck). Installing upside-down reduces lift and can cause poor cut or damage.
• Pairing: Sold as a 2-pack; you need two for a 36″ deck and three for a 48″ deck (buy an additional pack).

Should You Buy It

Yes, if you own one of the listed Exmark walk-behind models and want OEM-grade fit, consistent bagging performance, and reduced vibration. Skip if you have a different brand, a zero-turn, or need a mulching blade (this is high-lift, not mulching). At $57.98 for two, it’s a fair price for OEM quality—worth it for commercial users or homeowners who mow tall, thick grass.
