Exmark 116-5177-S Extreme Blade Set Lazer Z Vantage AS CT HP 48 Inch 3 Pack Red

What It Is

The Exmark 116-5177-S Extreme Blade Set is a factory OEM replacement blade set specifically designed for 48-inch Exmark Lazer Z, Vantage, AS, CT, and HP zero-turn mowers. These high-lift blades are built for heavy-duty cutting in tall, thick, or wet grass, delivering a clean, mulching-style discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch deck and uses three blades (each 16.5 inches long with a 1-inch center hole and 0.25-inch thickness). This set fits Exmark Lazer Z (all series), Vantage, AS, CT, and HP models with 48-inch decks. It is OEM Exmark, not an aftermarket copy—meaning exact fit and no modification needed. Check your owner’s manual or measure your current blade’s length, center hole diameter, and thickness. Not compatible with 36-, 52-, or 60-inch decks.

Key Things to Know

• High-lift design creates strong suction for better bagging and discharge, but will wear faster in sandy or rocky conditions than standard blades.
• Installation difficulty is low—use a 15/16-inch socket and torque to 70–90 ft-lbs. Always sharpen new blades before first use (they come unsharpened).
• Common gotcha: These blades are not for mulching kits—they are high-lift, not mulch. If you want finer clipping, pair with a mulching plug or buy dedicated mulch blades.
• Red powder coating is cosmetic only; it will wear off quickly. Do not re-sharpen more than 1/8 inch from the cutting edge or balance will be lost.

Should You Buy It

Buy this set if you own a 48-inch Exmark zero-turn and need factory-grade replacement blades for thick, tall grass or frequent bagging. Skip it if you mow sandy soil (consider hardened or low-lift blades) or want a budget aftermarket option—this is the premium OEM choice.
