Fengind 21" Lawn Mower Blade 5101755S – 5/8" Bore, Hardened Steel, Fits 61" Decks (5020842S Compatible)

The Fengind 5101755S lawn mower blade is a heavy-duty 21-inch replacement blade with a 5/8-inch center hole designed to restore clean, even cuts to 61-inch mower decks compatible with 5020842S and several OEM part numbers.

If your mower has grown uneven or is throwing clippings instead of cutting cleanly, the Fengind 5101755S offers a rugged, drop-in replacement engineered to match common 61-inch commercial and residential decks. Built from hardened steel and finished for corrosion resistance, this blade is sized and shaped to fit a range of machines — including scag, ferris, grasshopper, bad boy and Husqvarna models — that use the 5020842S/15208425S family of parts.

How will this blade improve my lawn’s appearance?

The 5101755S is formed for a clean shearing action that reduces tearing and fraying of grass, giving lawns a neater finish. Because it keeps a sharper edge longer than generic replacements, it produces even clippings and a uniform height across the cutting path.

• 21 inches long and 2.5 inches wide for full deck coverage
• Sharpened cutting lips for a crisp cut across turf types
• Balanced design reduces vibration and improves edge life

Which mowers and part numbers are compatible?

This blade is intentionally compatible with multiple 61-inch mower platforms that accept a 5/8" center bore and the 5020842S-style mounting pattern. It replaces or fits alongside part numbers such as 5020842S, 15208425S, 48111, and 481708 on many commercial decks.

• Works with scag, ferris, grasshopper and bad boy 61" decks
• Fits Husqvarna 61" decks using the three-blade 5020842S mounting setup
• Center hole diameter: 5/8" to match common spindles and hardware

How easy is installation and routine maintenance?

Installation is straightforward: the circular center hole and bolt pattern align with standard 61-inch spindles, letting you swap blades with common hand tools. Routine maintenance requires only periodic inspection and sharpening; replace the blade if bends or significant chips appear.

• Direct fit dimensions: 21" length, 2.5" width, 5/8" center bore
• Balanced for vibration-free mounting, reducing wear on spindles
• Sharpen or replace seasonally depending on usage and turf conditions

What durability and support can I expect?

Manufactured from hardened steel, the blade resists chips and bending when it encounters roots or small stones. A corrosion-resistant finish slows rusting, and the product is backed by a one-year maintenance support window with responsive customer service for installation or warranty questions.

• Hardened steel construction for enhanced impact resistance
• Protective finish to limit rust and extend service life
• One-year maintenance support and timely customer assistance

Who is this for: The Fengind 5101755S blade suits homeowners and professional landscapers who run 61-inch mower decks and need a direct-fit, durable replacement that restores cutting performance. It’s ideal when you want a cost-effective, OEM-compatible blade that’s easy to install, balances reliably, and extends the time between replacements while delivering a clean, professional-looking cut.
