103-6401 103-6381 High Lift Blades for 48 inch Exmark Lazer Z CT Turf Tracer Mower Decks Replace 103-6381-S 103-6401-S Toro 109-6872 (3 Pack)

What It Is

This is a 3-pack of high-lift replacement blades designed for 48-inch Exmark Lazer Z, CT, and Turf Tracer mower decks. The high-lift design increases airflow for better grass clipping discharge and bagging performance, making it ideal for thick or wet grass conditions.

Fitment & Compatibility

Before buying, verify your deck size is exactly 48 inches—these blades will not fit 36, 44, 52, or 60-inch decks. Compatible with Exmark Lazer Z, CT, and Turf Tracer models with 48-inch fabricated or stamped decks. Also fits Toro 48-inch decks using OEM part 109-6872. Cross-references include Exmark OEM parts 103-6401-S and 103-6381-S. Measure your existing blade: center hole diameter should be 1 inch, overall length approximately 16.25 inches, and width about 2.5 inches. Confirm your spindle pattern matches the blade’s mounting holes (typically 2-hole or 3-hole pattern—check your deck).

Key Things to Know

• Quality: Aftermarket blades at a lower price than OEM; steel thickness is adequate but may not last as long as genuine Exmark blades in heavy use.
• Installation: Easy to swap with basic tools—use a socket wrench and a block of wood to lock the blade. Torque spindle bolts to 70–90 ft-lbs. Always sharpen new blades before first use.
• Common gotcha: High-lift blades create more upward suction, which can cause the mower to “float” on soft turf or scalping on uneven ground. Reduce ground speed in thick grass to avoid strain on the engine and belt.
• Noise: Expect slightly louder operation compared to standard or low-lift blades due to increased airflow.

Should You Buy It

If you own a 48-inch Exmark Lazer Z, CT, or Turf Tracer and need a budget-friendly 3-pack for regular bagging or heavy grass, this is a solid value. Not ideal for commercial users who need maximum blade longevity or for mowing on extremely bumpy terrain where high-lift blades can cause scalping.
