8TEN LawnRAZOR Blade Set for Exmark Lazer Z XP AS E-Series S-Series 60 Inch Deck 103-6403 103-6403-S (High Lift) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade Set is a high-lift replacement blade pack for Exmark Lazer Z XP, AS, E-Series, and S-Series mowers with a 60-inch deck. Designed for heavy-duty cutting and superior bagging or discharge, these blades suit commercial operators or homeowners with thick, wet grass.

Fitment & Compatibility

• Deck size: 60-inch only; verify your deck measures exactly 60 inches across.
• Model compatibility: Fits Exmark Lazer Z XP, Lazer Z AS, Lazer Z E-Series, and Lazer Z S-Series (check your model tag under the seat or deck).
• OEM crossover: Replaces Exmark part numbers 103-6403 and 103-6403-S (high-lift). Confirm your current blade part number matches.
• Measurements: Blade length is 20.5 inches, center hole diameter 0.75 inches, thickness 0.25 inches. Measure your old blade to confirm fit—some 60-inch decks use 20.25-inch blades.
• What to check: Count your spindles—a 60-inch deck has three blades. Ensure you have three blades in the pack (this is a 3-pack). Verify your deck uses high-lift blades (some Exmark decks require standard or low-lift for mulching).

Key Things to Know

• Quality: LawnRAZOR blades are heat-treated, hardened steel with a corrosion-resistant coating. Expect slightly less edge retention than OEM Exmark blades but good performance for the price.
• Installation: Easy—remove the old blade, clean the spindle, and torque to 70-90 ft-lbs (check your manual). Use a blade removal tool or impact wrench. No special adapters needed.
• Common gotcha: High-lift blades create more airflow for bagging but increase engine load—may bog on underpowered or older mowers. Not ideal for mulching (use a mulching blade set instead).
• Balancing: Blades come pre-balanced, but always check with a balancer before install to avoid vibration and spindle wear.

Should You Buy It

Buy this set if you need a reliable, budget-friendly high-lift replacement for your Exmark Lazer Z 60-inch deck and primarily bag or side-discharge. It’s a solid value for commercial users who go through blades quickly or homeowners wanting OEM-like performance without the OEM price. Skip if you mulch or need maximum edge life for heavy commercial use—stick with OEM or premium aftermarket.
