Exmark 116-5174-S Extreme Blade Set Lazer Z AC AS LC XP XS Turf Tracer 60 Inch 3 Pack

What It Is

This is a factory OEM 3-pack of Exmark 116-5174-S Extreme blades designed for 60-inch zero-turn mowers, specifically the Lazer Z, AC, AS, LC, XP, XS, and Turf Tracer models. They’re built for heavy commercial use, delivering a fine, even cut on turf.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 60 inches—these blades won’t fit 48” or 72” decks. Check your mower model: this set is for Lazer Z (all series), AC, AS, LC, XP, XS, and Turf Tracer. Do not rely on “universal” fit; verify your existing blade part number matches 116-5174-S. OEM-only—aftermarket blades may vary in thickness (0.203” vs 0.187”) or hole pattern, causing vibration or poor cut. Measure blade length: 20.5 inches, center hole 5/8”, and two offset mounting holes. If your current blades are worn or bent, replace all three at once for balance.

Key Things to Know

• Quality: These are Exmark’s top-tier Extreme blades, heat-treated for durability and sharpness retention. They last longer than standard or aftermarket options in sandy or rough terrain.
• Installation: Moderate difficulty. You’ll need a torque wrench (set to 70-90 ft-lbs) and a blade removal tool. Always lift the deck with jack stands—never rely on the mower’s hydraulics. Reuse the original washers and spacers; do not overtighten.
• Common Gotchas: If your mower has a different blade part number (e.g., 116-5174-S vs 116-5174), double-check the suffix—older models may use a different offset. Also, these blades are not for mulching; they’re high-lift for side discharge. Running them with a mulching plug will cause poor grass flow and clumping.
• Performance: Expect a 10-15% increase in cut quality over OEM standard blades, but battery drain on electric decks may increase due to higher lift.

Should You Buy It

Yes—if you own a compatible Exmark 60” zero-turn and want OEM-grade durability and a pristine cut for commercial or large residential lawns. Skip them if you need mulching blades or have a different brand deck (e.g., Toro or Scag won’t fit). For the price, this is a solid investment for pros who mow weekly.
