IDEASURE 48" High-Lift Lawn Mower Blades 3-Pack for 48in Decks — Heavy-Gauge Steel, 5/8" Center

These IDEASURE 5020843S high-lift blades are a 3-pack of heavy-gauge steel replacement blades engineered to restore cutting performance for 48" mower decks compatible with Ferris, Exmark, Gravely, Bobcat and similar machines.

Replacing worn or damaged blades is one of the quickest ways to improve cut quality and reduce mowing time. The IDEASURE 5020843S blades are manufactured from a single piece of thick steel and shaped for high-lift airflow, giving consistent clipping evacuation and a neater finish across a wide range of turf conditions. Confirm deck size and center hole diameter before fitting to ensure proper match.

How do these blades improve mowing performance?

High-lift blades create stronger suction that lifts grass into the cutting plane, producing a cleaner, more uniform cut and better collection in bagging systems. The thicker steel construction resists bending and maintains edge geometry longer, so you need to sharpen or replace them less often.

• High-lift profile for improved grass pick-up and discharge
• Thick single-piece steel resists warping and impact
• Consistent edge retention for uniform mowing lines

Which machines will these blades work with?

These blades are designed for many commercial and residential 48" decks. They explicitly replace OEM numbers used by Ferris, Exmark, Gravely, Bobcat and several other manufacturers, making them a convenient aftermarket option when OEM blades are unavailable or costly.

• Replaces Ferris 1520843 / 5020843 and similar part numbers
• Compatible with Exmark Lazer Z, Turf Ranger, and related models
• Fits Gravely Pro, Ariens 2048/2148/2348, and many 48" walk-behind units

What are the exact specifications and fit checks?

Each pack contains three identical blades sized for a standard 48" deck. Check the blade length, width, thickness and center hole diameter against your mower’s current blade before purchasing to ensure fitment and safe operation.

• Length: 16-1/4"; Width: 2-1/2"; Thickness: 0.197"
• Center hole diameter: 5/8" (measure your spindle bolt clearance)
• Sold as a 3-pack—install all blades at the same time for balanced rotation

How should I install and maintain these blades?

Installation requires lifting the mower safely and removing the old blade bolts with the engine off and spark plug disconnected. Tighten to manufacturer torque specs, balance blades after installation, and routinely inspect for nicks or bending to maintain cutting quality and safety.

• Disconnect spark plug and secure mower before working underneath
• Tighten blade bolts to your mower manufacturer’s torque settings
• Sharpen or replace blades when nicked, bent, or worn beyond spec

Who is this for: The IDEASURE 5020843S 3-pack is suited for homeowners, landscapers and fleet managers who run 48" decks and need durable, high-lift replacement blades that match common OEM part numbers. If you service multiple mowers or want a reliable aftermarket alternative for Ferris, Exmark, Gravely, Bobcat or comparable brands, this set offers a cost-effective way to restore cutting quality and airflow on your deck.
