8TEN LawnRAZOR Blade Set for Exmark Lazer Z E S X Series 72-Inch Deck 103-6384 (High Lift) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade Set is a high-lift replacement blade set for Exmark Lazer Z E, S, and X Series mowers with a 72-inch deck. Designed for superior grass discharge and bagging performance, it’s ideal for commercial or residential users cutting thick, tall, or wet grass.

Fitment & Compatibility

• Deck size: Only for 72-inch Exmark Lazer Z E, S, and X Series decks. Measure your deck to confirm.
• OEM part: Replaces Exmark OEM part number 103-6384. Verify your current blade has this number stamped on it.
• Dimensions: Each blade is 22.5 inches long, 2.5 inches wide, with a 0.203-inch thickness and a 7/16-inch center hole. Measure your blade’s length and hole size to match.
• Set: Comes as a 3-pack (one set for a 72-inch deck). Check your spindle count—72-inch Exmark decks use three blades.
• Aftermarket note: These are aftermarket, not OEM. Fitment is direct, but quality may vary—read reviews for your specific mower model.

Key Things to Know

• High-lift design: Excellent for bagging and side discharge, but creates more dust and wear on the deck. Not ideal for mulching.
• Installation: Straightforward swap if you have a socket wrench and torque wrench. Tighten blade bolts to 70–90 ft-lbs. Check blade orientation—cutting edge faces rotation direction.
• Balance: Each blade is balanced from factory, but always recheck with a blade balancer before installing to avoid vibration.
• Common gotcha: The center hole is 7/16-inch, but some Exmark spindles use a 5/8-inch hole. Measure your spindle bolt before buying—if it’s larger, this set won’t fit.

Should You Buy It

Buy this set if you need a cost-effective high-lift replacement for a 72-inch Exmark Lazer Z and primarily bag or side-discharge. Skip it if you mulch or have a different deck size—look for a mulching blade set or confirm your spindle hole size first.
