GUSUHAWK 2-Pack GX20249 Mulching Mower Blades for John Deere 42" Deck — Pre-Sharpened, Rust-Resistant

GUSUHAWK GX20249 2-pack mower blades are premium mulching replacements engineered to fit 42" John Deere decks (L110, L111, L118 and compatible models) for cleaner cuts and long life.

These two pre-sharpened mulching blades replicate the John Deere GX20249 profile and mounting hole, offering a direct-fit upgrade for 42" decks. Manufactured from heavy-duty high-strength steel with a powder-coated, rust-resistant finish, they arrive ready to install and balance airflow for efficient mulching and clipping discharge. The blades match common OEM part numbers (GX20249, GX20433, GY20567, 330-615) and the round 11/16" center hole pattern used on many L-series residential mowers.

How do these blades improve mowing performance?

The GUSUHAWK blades use a mulching lift geometry that creates stronger airflow under the deck so clippings are chopped finer and spread more evenly. That reduces clump-building and produces a neater finish in one pass.

• Pre-sharpened edges for immediate use and reduced tear-out
• Angled lift design increases clipping circulation
• Powder-coated surface resists rust and speeds cleanup
• 0.17" thickness and 2 7/16" width for durable cutting edge retention

Will these blades fit my John Deere mower model?

They’re designed for 42" decks and explicitly match John Deere part fitments and hole patterns for many L-series models. Check blade length and the 11/16" round center hole to confirm compatibility before purchase.

• Length: 21 3/8" — matches 42" deck blade radius
• Center hole: round 11/16" to fit common spindle bolts
• Compatible models listed include L100, L105, L107, L108, L110, L111, L118
• Also fits several Sabre, SABO and Scotts models with the same deck size

How easy is installation and maintenance?

Installation is straightforward and typically takes minutes with basic tools — remove the old blade, align the center hole, and torque the mounting bolt to factory specs. The blades arrive pre-coated and pre-sharpened; when they dull, they re-sharpen easily to extend service life.

• Install with a torque wrench and common socket set
• Cutting edge orientation clearly marked for correct mounting
• Powder-coat finish minimizes surface corrosion between uses
• Resharpenable steel construction for long-term value

What are the specs and safety reminders I should know?

These blades measure 21 3/8" long with a 2 7/16" width and 0.17" thickness and are intended for mulching applications. Always disconnect the spark plug and follow mower manufacturer torque and safety instructions during blade change.

• Blade type: mulching lift; air lift 1" for improved airflow
• Replaces OEM GX20249, GX20433, GY20567, 330-615
• Made from high-strength steel with rust-resistant coating
• Safety: wear gloves, secure mower, and use proper torque on bolts

Who is this for? Homeowners and small-property caretakers with John Deere 42" deck mowers (L-series and compatible models) who want a cost-effective, durable blade pair that restores cutting performance and improves mulching. These blades suit routine seasonal replacements or upgrades for cleaner, more consistent lawn results without custom fitting or machining.
