8TEN LawnRAZOR Blade Set for Exmark Lazer Z Turf Tracer Toro 60 Inch 103-2530 115-9649-03 (Toothed Mulching) 3 Pack

What It Is

This is a 3-pack of toothed mulching blades (part numbers 103-2530, 115-9649-03) designed for 60-inch Exmark Lazer Z and Toro Turf Tracer mowers. They replace OEM blades to improve grass clipping shredding and nutrient recycling.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch deck (not 48-inch or 52-inch). These blades fit:

• Exmark: Lazer Z, Turf Tracer (select models with 60-inch decks)
• Toro: Turf Tracer (60-inch) – check your model number against Toro’s parts list (e.g., 30168, 30169)
• OEM replacements: 103-2530 (Toro), 115-9649-03 (Exmark)
• Measurements: Blade length 20.5 inches, center hole 7/8-inch diameter, 5-point star drive. Verify your spindle’s blade-mounting pattern matches (most Exmark/Toro 60-inch use this pattern). Use a ruler or caliper to confirm your existing blade length and hole size.

Key Things to Know

• Quality: 8TEN blades are heat-treated, hardened steel – durable for residential/commercial use, but not OEM. Check for balance out of the box; some users report minor imbalance requiring filing.
• Installation: Moderate difficulty – requires a socket set and torque wrench (recommended 70-90 ft-lbs). Use thread locker on spindle bolts. The toothed design is aggressive; ensure blade tips don’t contact deck sides.
• Common gotcha: These are mulching blades, not lift blades. They won’t discharge or bag as effectively. If you switch from standard blades, expect finer clippings but possible clumping in wet grass.
• Pack quantity: 3 blades – enough for a 60-inch deck (typically uses 3 spindles). No spacers or hardware included.

Should You Buy It

Buy if you own a compatible Exmark or Toro 60-inch mower and want to upgrade from standard blades to better mulching performance. Skip if you need OEM-specific fitment, bagging/discharge capability, or if your deck uses a different blade pattern (e.g., 52-inch or 72-inch). The price is fair for a 3-pack, but verify fitment carefully – returning wrong-size blades is a hassle.
