103-6398-S 116-5174-S Extreme Blade Fit for 60 Inch Deck Exmark Lazer Z AC AS LC XP XS Turf Tracer Mower 6 Pack

What It Is

This is a 6-pack of aftermarket mower blades designed for 60-inch Exmark Lazer Z and Turf Tracer zero-turn mowers. The blades (part numbers 103-6398-S and 116-5174-S) are for medium-duty residential or light commercial cutting, not heavy commercial use.

Fitment & Compatibility

• Deck size: 60 inches only. Will not fit 48-, 52-, or 72-inch decks.
• Exmark models: Lazer Z AC, AS, LC, XP, XS, and Turf Tracer. Also fits some Toro and Scag equivalents with the same spindle pattern.
• OEM cross: Replaces Exmark OEM part numbers 103-6398-S and 116-5174-S. Aftermarket, not OEM.
• Measurements: Blade length 20.5 inches, center hole 0.625 inches (5/8”), oval drive hole. Measure your existing blade’s length and hole shape before buying.
• Check spindle offset: These blades have a slight upward angle at the tips. If your deck requires a completely flat blade, they won’t work.

Key Things to Know

• Quality concerns: 3.2-star rating with reports of blades arriving bent or unbalanced. Inspect each blade before installing.
• Installation: Easy bolt-on if you have a torque wrench. Tighten to 70-80 ft-lbs. Use thread locker on the bolts.
• Sharp vs. dull: Some users report they go dull faster than OEM blades, especially in sandy or rocky soil. Expect to sharpen or replace more often.
• Warranty: Typically 30-day return window. No long-term guarantee.

Should You Buy It

Buy this 6-pack if you need budget blades for a 60-inch Exmark and are willing to inspect and balance each one before use. It’s a good value for light mowing on clean, manicured lawns. Skip it for heavy commercial cutting, rocky terrain, or if you want the durability and consistent sharpness of OEM blades.
