What It Is

A set of three mulching blades designed for 48-inch zero-turn mower decks, specifically for Exmark Lazer Z and Vantage models. These blades chop clippings into fine particles to return nutrients to the lawn, ideal for frequent mowing without bagging.

Fitment & Compatibility

• Deck size: 48-inch only. Measure your deck before ordering—this is not for 52- or 60-inch decks.
• OEM replacements: Directly replaces Exmark part numbers 103-6401, 103-6401-S, 103-6381, 103-6381-S, 103-6391, 103-6391-S, 103-6396, and 103-6396-S.
• Model fit: Fits Turf Tracer, Lazer Z, and Vantage with 48" deck. Confirm your specific model year—older Lazer Z models may require different blade offset.
• Measurements: Each blade is approximately 18.5 inches long, 2.5 inches wide, with a 5/8-inch center hole and 1/4-inch pin holes. Check your spindle bolt pattern matches (typically 5/8" hex).

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish. Durability is good for residential and light commercial use, but may dull faster than OEM or premium blades in heavy debris.
• Installation: Standard bolt-on—use a torque wrench to 70-80 ft-lbs. No special tools required, but ensure blades are oriented with the lift wing facing up toward the deck.
• Balance: Some users report minor balance issues out of the box. Check each blade on a balancer before installing to avoid vibration and spindle wear.
• Common gotcha: These are mulching blades, not high-lift. They won’t bag or side-discharge effectively. If you need to bag, stick with OEM or dedicated bagging blades.

Should You Buy It

If you own a 48-inch Exmark Lazer Z or Vantage and want an affordable mulching upgrade that matches OEM specs, this three-pack is a solid value. It’s best for homeowners or light commercial users who mow frequently and don’t need bagging performance. Skip it if you run in heavy debris, need high-lift action, or want OEM-level longevity.
