Genuine OEM TORO PARTS - BLADE-21 INCH 91-2256-03

What It Is

This is a genuine OEM Toro 21-inch replacement blade (part number 91-2256-03) for select Toro walk-behind mowers. It’s designed for standard residential cutting and bagging on flat or moderately uneven turf.

Fitment & Compatibility

• Deck size: Only fits 21-inch cutting decks. Measure your blade’s length from tip to tip before ordering.
• Model check: Works with Toro Recycler, Super Recycler, and some Personal Pace models (e.g., 20065, 20370, 21380). Verify your mower’s model number on the deck or under the seat.
• OEM vs aftermarket: This is genuine Toro, so it matches factory specs exactly. Aftermarket blades may differ in thickness, hole alignment, or balance.
• Measurements: Blade length 21”, center hole 1” diameter, with a 5-point star drive pattern. Check your old blade’s hole shape—some Toro models use a different pattern.
• What to check before buying: Confirm your mower’s model number, blade length, and that you have a 5-point star hole (not a round or oval hole). Also ensure your spindle is in good shape.

Key Things to Know

• Quality: Made from hardened steel with a coated finish to resist rust. Edge holds up well for 1–2 seasons with normal use.
• Installation difficulty: Easy—requires a socket wrench or torque wrench. Torque blade bolt to 55–65 ft-lbs. Use a blade stop or block to prevent rotation while tightening.
• Common gotcha: The star drive pattern can be tight on older spindles. If the blade doesn’t seat flush, don’t force it—check for debris or a worn spindle.
• Balance: Pre-balanced from factory, but always check after sharpening. An unbalanced blade causes vibration and can damage the spindle.

Should You Buy It

If you own a compatible Toro 21-inch mower and want a direct, hassle-free replacement that matches factory performance, this is the right choice. It’s ideal for homeowners who value durability and proper fit over saving a few dollars on generic blades. Skip it if you have a different deck size or a non-Toro mower.
