191V96-5 21" Lawn Mower Blade Compatible with Ma-Kita XML11 & XML10 Mower 3-in-1 Blade - Mulching, Bagging, Side Discharge Replacement Blade

What It Is

This is a 21-inch 3-in-1 lawn mower blade designed for mulching, bagging, and side discharge. It’s a replacement blade specifically for Ma-Kita XML11 and XML10 cordless mowers.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Your mower must have a 21-inch cutting deck. Measure the blade length (hole center to opposite tip) to confirm.
• Model: This blade is engineered for Ma-Kita XML11 and XML10 models. It will not fit other brands or most gas mowers without modification.
• Center hole & drive: Check the center hole diameter (typically 6.5mm on these mowers) and ensure the blade’s drive pin pattern matches your mower’s spindle. OEM part number is 191V96-5; aftermarket blades like this one may vary slightly in thickness or balance.

Key Things to Know

• Quality concerns: With a 3.0 rating from only 7 reviews, expect possible balance issues or shorter lifespan than OEM. Inspect for warping out of the box.
• Installation difficulty: Easy—requires a 14mm socket or wrench to remove the center nut. No special tools needed, but a torque wrench (25-35 ft-lbs) is recommended to avoid stripping.
• Common gotcha: This blade is thinner than some OEM versions, which can reduce mulching efficiency and increase vibration. Use a blade balancer before installing.
• Performance trade-off: The 3-in-1 design works for all discharge modes, but dedicated mulching blades typically cut grass finer.

Should You Buy It

Buy this only if you own a Ma-Kita XML11 or XML10 and need a budget-friendly 3-in-1 replacement. It’s acceptable for occasional use where OEM blades are unavailable, but the low rating and potential quality issues make the OEM blade a safer long-term choice for regular cutting.
