Fismiuta 21-Inch Mulching Blade 2-Pack — High-Carbon Steel, 3-in-1 Mulch/Bag/Side-Discharge

The Fismiuta 21-inch mulching blade is a heavy-duty replacement blade engineered to restore cutting performance on compatible walk-behind mowers by mulching, bagging, or side-discharging clippings.

If your 21" walk-behind mower is leaving uneven cuts, clogged decks, or slow grass pickup, this two-piece Fismiuta blade set is built to bring back reliable airflow and clean slicing. Made from high-carbon steel with a rust-resistant finish and an increased air-lift profile, these blades are sized and shaped to match many common OEM part numbers used by Troy-Bilt, Cub Cadet, MTD and Craftsman machines.

How does this blade improve mowing performance?

The raised air-lift design increases suction under the deck so clippings are pulled up and shredded rather than tossed. That means faster bag filling, fewer clumps on the lawn, and a finer return of nutrients when mulching.

• 32mm (1-1/8") air-lift height for stronger airflow and better bag collection
• Sharpened cutting edges for cleaner, even cuts that reduce scalping
• 3-in-1 capability: mulch, bag, or side-discharge without swapping blades

Will these blades fit my mower model and spindle?

These blades are manufactured to match the 21" deck dimensions and common hole pattern listed in the specs, but they only fit bow-tie shaped center holes. Verify compatibility using your OEM part number or the center hole shape before ordering.

• Replaces OEM numbers such as 742-0741, 942-0741, 742-04276, and similar
• Compatible with many Troy-Bilt, Cub Cadet, MTD and Craftsman walk-behind models (see product details)
• Deck length 21" and bow-tie center hole required for proper fit

What materials and durability features does this blade include?

Constructed from high-carbon steel, these blades balance edge retention and impact resistance for routine lawn conditions and light-to-moderate weeds. A protective coating resists surface rust during storage and installation; the blade can be resharpened when needed.

• Forged high-carbon steel resists dulling and bending
• Rust-resistant finish for protection before first use
• Sharpenable design to extend service life and maintain cut quality

How do I confirm dimensions before buying?

Measure your current blade or mower deck and check the center hole shape. This Fismiuta set lists explicit dimensions so you can match length, width, thickness and lift height to your mower’s requirements.

• Length: 21" (533 mm); Width: 2-1/4" (57 mm)
• Thickness: 9/64" (3.4 mm); Air lift: 1-1/8" (32 mm)
• Center hole: bow-tie pattern — confirm spindle type to avoid returns

Who this is for: Homeowners and lawn-care pros with 21" walk-behind mowers who need a durable, higher-lift replacement blade that restores bagging efficiency, improves mulching, and fits common Troy-Bilt/Cub Cadet/MTD/Craftsman models. If you want stronger deck airflow, reliable edge retention, and a blade that matches well-known OEM part numbers, this two-pack offers an economical fix to refresh cutting performance.
