Exmark 109-6468-S Hi Lift Solid Blade Lazer Z HP LHP23KA565 LHP27KC565 3 Pack

What It Is

The Exmark 109-6468-S is a genuine OEM high-lift (hi-lift) solid blade designed for maximum airflow and debris discharge. It’s intended for Exmark Lazer Z HP mowers used in commercial or heavy residential cutting, especially in tall or wet grass where bagging or clean side-discharge is critical.

Fitment & Compatibility

Before buying, verify your mower’s model and deck size. This 3-pack fits:

• Exmark Lazer Z HP models: LHP23KA565 (23hp Kawasaki, 60" deck) and LHP27KC565 (27hp Kohler, 60" deck).
• Deck size: 60-inch cutting width only. These blades are 20.5 inches long with a 1-inch center hole and 0.203-inch thickness.
• OEM vs aftermarket: This is an Exmark genuine part (OEM #109-6468-S). Aftermarket equivalents exist but may differ in steel quality, lift height, or balance. Check your blade’s current part number stamped on it for exact match.
• What to measure: Remove one existing blade and confirm length (20.5”), center hole diameter (1”), and thickness (0.203”). Also ensure your spindle mount uses a single center bolt (common on Exmark 60” decks).

Key Things to Know

• High-lift vs standard: These blades create strong upward suction. They improve bagging and discharge but increase engine load and fuel consumption slightly. Not ideal for dry, dusty conditions where they may kick up debris.
• Installation difficulty: Easy—requires a socket wrench (typically 15/16” or 1” bolt) and a blade removal tool or block of wood to prevent spinning. Torque to 70–90 ft-lbs. Always disconnect spark plug first.
• Sharpening & lifespan: Hi-lift blades dull faster than low-lift or mulching blades due to increased air contact. Expect 2–3 sharpening cycles before replacement. Never sharpen beyond 1/8” of original edge width.
• Common gotcha: Mixing hi-lift blades with standard or mulching blades on the same deck causes vibration and uneven cut. Replace all three at once for balance.

Should You Buy It

Buy this if you own a 60” Exmark Lazer Z HP and regularly mow thick, tall, or wet grass where clean discharge or bagging is a priority. Skip it if you mostly cut dry, short grass or prefer mulching—consider Exmark’s mulching or standard-lift blades instead. This pack is a solid OEM choice for commercial operators who need consistent lift and durability.
