8TEN LawnRAZOR Blade for Exmark Lazer Z HP CT 44" Deck 103-2529-S (Notched High Lift) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade for Exmark Lazer Z HP CT 44" Deck is a notched high-lift replacement blade designed for commercial zero-turn mowers. It enhances grass clipping discharge and bagging performance on 44-inch Exmark decks, especially in tall or wet grass.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Fits Exmark 44" Lazer Z HP and CT models only. Measure your deck width (blade tip to tip) to confirm.
• OEM part number: Replaces Exmark OEM 103-2529-S. Check your current blade for this number or look up your mower’s parts diagram.
• Blade dimensions: 16.5" long, 2.5" wide, 0.204" thick, with a 1" center hole and notched ends. Measure your old blade to match.

Not compatible with other Exmark deck sizes (48", 52", 60") or non-Exmark brands without adapter kits.

Key Things to Know

• Material: Heat-treated steel with a protective coating for rust resistance. Sharper out of the box than many OEM blades.
• Installation difficulty: Easy if you have a socket wrench and blade removal tool. Torque bolts to 70-80 ft-lbs. Notched design aligns with spindle pins—no special adapters needed.
• Common gotchas: High-lift blades increase noise and vibration slightly. Not ideal for sandy soil (accelerates wear). Ensure blade bolts are not stripped before installing.
• Balance: Pre-balanced, but always check with a balancer after sharpening to avoid deck wobble.

Should You Buy It

If you own an Exmark Lazer Z HP or CT with a 44" deck and need reliable, sharp aftermarket blades for frequent bagging or mulching in heavy grass, this 3-pack offers good value. Skip it if you prefer OEM blades for warranty reasons or mow in extremely sandy conditions.
