3-Pack Exmark Contractor Pro 60" High-Lift Notched Mower Blades by OEM Parts Distribution – Replaces Exmark 103-6403/103-6403-S, Toro 140-1240 – Fits Lazer Z, Turf Tracer, Pioneer, Vantage

What It Is

This is a 3-pack of high-lift notched mower blades designed for heavy-duty commercial mowing on 60" Exmark and Toro zero-turn mowers. The notched design increases airflow for superior grass lifting and bagging, making it ideal for tall, wet, or dense turf in professional landscaping use.

Fitment & Compatibility

• Deck size: 60-inch cutting deck only.
• Models: Fits Exmark Lazer Z, Turf Tracer, Pioneer, and Vantage series. Also fits Toro Z-Master and Groundsmaster 7200/7210 models using the same blade pattern.
• OEM cross-reference: Replaces Exmark 103-6403/103-6403-S and Toro 140-1240.
• Measurements: Blade length is 20.5 inches, center hole diameter is 0.625 inches, and notch spacing is 3.0 inches. Verify your blade’s center hole and notch alignment before buying—these are not universal.
• Check: Confirm your spindle bolt pattern; these blades require a 5/8" center hole and specific notch orientation to avoid hitting the deck shell. Measure your old blade length and hole size to be safe.

Key Things to Know

• Quality: Made by OEM Parts Distribution (aftermarket). Expect good steel but may require balancing before install—some users report slight weight inconsistencies out of the pack.
• Installation difficulty: Moderate. You’ll need a torque wrench (spindle bolts typically 70-90 ft-lbs) and a blade removal tool. Notched blades are directional; ensure the notch faces the discharge chute.
• Common gotchas: The high-lift design creates more vibration if blades are unbalanced. Check blade tracking after install—bent spindles or uneven deck can cause poor cut. Also, these will wear faster than standard lift blades in sandy or rocky conditions.
• Price note: At $54.99 for a 3-pack, it’s a solid value vs. OEM ($25-30 per blade), but verify it’s not a knockoff—some counterfeit versions have wrong hole sizing.

Should You Buy It

If you have a 60" Exmark or Toro commercial zero-turn and need reliable high-lift blades for bagging or heavy grass, this pack is a cost-effective alternative to OEM. But if your deck is worn or you’re sensitive to vibration, buy OEM for guaranteed balance. Skip if your mower is a different brand or deck size.
