IDEASURE 18" High-Lift Notched Mower Blades — 2-Pack Compatible with 36" & 52" Decks, 5/8" Hole, 0.236" Thick

These two replacement blades are built to match OEM fit and function for many walk-behind and stand-on mowers that use 71440001 / 48108-style blades. Each blade measures 18" long, 2-1/2" wide and 0.236" thick with a 5/8" center hole, delivering strong suction and lift for cleaner clippings and even cutting across a range of grass types. Use two blades for a 36" deck or three blades for a 52" deck where specified; verify your deck and spindle measurements before ordering.

Will these blades fit my Wright, Exmark or other commercial mower?

These IDEASURE blades are designed as direct replacements for a broad set of part numbers used across brands, so they fit many commercial mower decks that accept 18" high-lift blades with a 5/8" center hole. Compatibility depends on deck size, blade hole diameter and mounting configuration. Always compare the blade dimensions and notch style to your existing blades before installing.

• Replaces part numbers including 71440001, 48108, 482878 and more
• Fits many Wright, S-cag, Exmark, Husqvarna and John Deere-type decks
• Two blades per pack — two needed for 36" decks, three for 52" decks
• Confirm 18" length, 0.236" thickness and 5/8" center hole

How do these high-lift notched blades affect cutting performance?

The notched, high-lift profile boosts airflow under the deck to lift grass upright before slicing, which helps produce a cleaner, more uniform cut. The single-piece thick-steel construction reduces flex and maintains edge geometry longer, improving striping and discharge. They are suited to a variety of turf conditions but should be matched to your mower’s intended use and deck design.

• High-lift shape increases grass lift and suction
• Notches aid clipping discharge and mulching compatibility
• Thick steel resists bending for consistent cut quality
• Works across different grass heights and terrains

What are the key specifications and installation tips?

Each blade in the pack measures 18" long, 2-1/2" wide and 0.236" thick with a 5/8" (0.625") center hole — standard dimensions for many commercial decks. Before installation, park the mower on level ground, disconnect the spark plug, and mark blade orientation to maintain balance. Replace blades in matched sets and torque mounting hardware to the manufacturer’s specification to avoid vibration and premature wear.

• Dimensions: 18" L × 2-1/2" W × 0.236" thick
• Center hole: 5/8"; confirm with your spindle bolt size
• Install blades as matched sets and tighten to OEM torque
• Disconnect power and follow safety steps when changing blades
