Makita 199367-2 18 in. Lawn Mower Blade

What It Is

This is an OEM replacement blade (part number 199367-2) for select Makita 18-inch cordless lawn mowers. It’s designed for residential use on small to medium lawns, delivering a clean cut with standard lift.

Fitment & Compatibility

• Deck size: Only fits 18-inch cutting deck mowers. Do not use on 16-inch, 20-inch, or other sizes.
• Model fit: Confirmed compatible with Makita models XMU03, XMU03Z, XMU04, XMU04Z, and MLT100. Not for older Makita mowers or other brands.
• OEM vs aftermarket: This is genuine Makita, not a universal or third-party blade. Aftermarket blades may require adapter plates or have different hole patterns.
• Measurements: Blade length is 18 inches (from tip to tip). Center hole is 7/8 inch diameter with a 5-point star drive pattern. Check your current blade’s hole shape—standard round holes won’t fit.
• What to check before buying: Confirm your mower model number (on the deck or manual). Measure your existing blade’s length and center hole shape. Verify the blade is for cutting, not mulching—this is a high-lift blade, not a mulching blade.

Key Things to Know

• Quality: OEM steel blade with balanced design. Holds edge well for 20-30 mows on typical turf, but dulls faster on thick or wet grass.
• Installation difficulty: Easy—requires a 14mm wrench or socket. Torque to 35-40 ft-lbs. Use a blade stop or block wood to prevent spinning. No special tools needed.
• Common gotchas: The star drive hole is specific to Makita—won’t fit most aftermarket blade adapters. If you need a mulching blade, this is not it (it’s a standard lift blade). Always replace in pairs if your mower has two blades (most 18-inch Makita models use one blade).
• Sharpening: Can be sharpened 2-3 times, but replacement is cheap enough to swap when dull.

Should You Buy It

If you own a compatible Makita 18-inch mower and need a direct OEM replacement for standard cutting, this is the right blade. It’s affordable, fits perfectly, and delivers reliable performance. Skip it if you want a mulching blade or need an aftermarket universal option—look for a dedicated mulching blade instead.
