8TEN LawnRAZOR 18.5" Medium-Lift Mower Blades for John Deere M115496 3-Pack — 54" Deck Fit, Sharp Edges

The 8TEN LawnRAZOR Medium-Lift 18½-inch mower blade 3-pack replaces John Deere M115496 and similar parts to restore clean cutting and consistent bagging on 54-inch decks.

If your John Deere or compatible mower is leaving uneven grass clippings, upgrading to fresh blades can make a noticeable difference. The 8TEN LawnRAZOR set is engineered to match the fit and basic lift profile of several John Deere and third-party OEM numbers, giving you a straight swap that preserves deck clearance and mulching or bagging performance. These blades are sized and punched to align with many 54-inch decks used across lawn and garden tractors.

Which machines will these blades fit?

These blades are designed to fit a wide range of John Deere tractors and several third-party models that use the same blade dimensions and center hole. Always compare the blade length, center hole diameter, thickness, and width to your existing blade before purchase to ensure compatibility.

• Compatible OEM part numbers: John Deere/Scotts M115496, M111523, M135590, M76467
• John Deere models: 325, 335, 345, F725, 355D, 425, 445, 455 with 54-inch decks
• Other John Deere series: GS30, GS45, GS75, HD45, HD75, G100, LX288 (54-inch decks)
• Also fits certain Sabre and Scotts 54-inch deck models

How do these blades affect cutting and collection performance?

The medium-lift profile balances airflow for bagging and side-discharge while avoiding excessive turf pull that high-lift blades can cause. New, uniformly sharp edges give cleaner cuts which reduce stress on grass and help the mower collect clippings more efficiently.

• Medium-lift shape improves bagging without extreme suction
• Sharp factory edges produce cleaner, healthier-looking cuts
• Consistent thickness and balance reduce vibration and uneven wear

What are the exact blade dimensions and mounting details?

Knowing precise measurements ensures you replace blades safely and without modifications. The 8TEN LawnRAZOR blades match the key specs required by many 54-inch decks so they mount directly to the spindle using the standard fastener pattern.

• Overall length: 18 1/2 inches
• Center hole diameter: 3/4 inch (0.75") to match spindle studs
• Material thickness: 0.197 inches; width: 2 1/2 inches

How should I install and maintain these replacement blades?

Installation follows the same steps as original equipment blades: disconnect the spark plug, secure the deck, remove the old blade(s), and torque the blade bolt to the mower manufacturer’s specification. Regular inspection, rotation and timely sharpening will keep cutting quality high and extend blade life.

• Always disconnect power and stabilize mower before working
• Retorque blade hardware per your tractor manual after installation
• Sharpen as needed and replace if bent, cracked or excessively worn

Who is this for: homeowners and small-property caretakers who use John Deere or compatible 54-inch deck riding mowers and need a direct-fit, medium-lift replacement blade set to restore cutting quality and bagging performance. This 3-pack is a convenient option for those who service multiple blades at once or keep spares on hand to minimize downtime during peak mowing season.
