DAOLONG 21-Inch Mower Blade 2-Pack — Fits Greenworks 21" Models, Heavy-Duty Heat-Treated Steel, Anti-Clog

These are two heavy-duty 21-inch replacement mower blades from DAOLONG engineered to fit Greenworks 21" mower models (C3208101, MO40L4413, MO40L03, MO48L4422) for reliable, one-pass cutting.

If your Greenworks mower is leaving uneven stripes, struggling with thick or wet grass, or the current blade is bent or chipped, swapping in a fresh set of DAOLONG blades restores cutting performance quickly. The pair is designed for home and small-plot use where durability, sharpness retention, and anti-clog performance matter. Each blade is heat-treated high-hardness steel, shaped to resist breakage and minimize grass buildup so you can mow with fewer interruptions.

How does this blade improve mowing performance?

The DAOLONG 21-inch blade is shaped and tempered to hold a sharp edge longer and cut cleanly in a single pass. A deliberate arc and cutting geometry reduce the tendency for grass to bunch or wrap, producing a neater finish and faster mowing times.

• Heat-treated steel edge for extended sharpness and consistent cuts
• Optimized arc profile to reduce clogging and prevent grass wrapping
• Balanced design for steady rotation and less vibration during use

Will these blades fit my Greenworks model and install easily?

Yes — the two blades are made to match the bolt pattern and sizing of several Greenworks 21" mower models including C3208101, MO40L4413, MO40L03, and MO48L4422. No special modifications are required; most homeowners can replace them with basic hand tools.

• Direct compatibility with listed Greenworks 21" models — no drilling or resizing
• Standard mounting holes and balanced center for quick installation
• Includes two blades so you have a spare for rotation or future replacement

How durable are these replacement blades under real-world conditions?

DAOLONG blades use quenched, high-hardness steel and controlled heat treatment to resist bending, chipping, and premature wear. They withstand typical yard debris like small stones and twigs better than thin, untreated blades, reducing the frequency of replacements.

• Quenched steel construction increases resistance to impact and edge damage
• Edge retention suited for thick, fast-growing lawns and wet grass
• Heavy-duty thickness reduces flexing on uneven terrain

How does the anti-clogging design benefit frequent mowing?

The blade's arc and profile are crafted to shed cut material and moisture, which helps maintain steady suction and discharge through the mower deck. That means fewer stops to clear clogs and more consistent clippings flow into the bag or mulching chamber.

• Anti-clog geometry prevents wet clippings from sticking to the blade
• Smoother discharge reduces stall risk during damp or rainy mowing
• Consistent airflow maintains cutting efficiency for longer passes

Who is this for: Homeowners, landscaping hobbyists, and weekend gardeners who own Greenworks 21" mowers and need a dependable, cost-effective blade replacement. If you want cleaner cuts, reduced clogging, and longer-lasting edges without complex installation, this DAOLONG 2-pack offers practical value for routine lawn maintenance and spare-part preparedness.
