[Upgrade] Knife Discs + 7 Pieces Blades Compatible with Mammotion LUBA Mini AWD Series 800 1500, Robotic Lawn Mower Blade Disc Lawn Robot Turntable

What It Is

This is an upgrade blade disc and blade set for Mammotion LUBA Mini AWD robotic mowers. It replaces the factory discs and blades, designed to improve cutting performance on the 800 and 1500 models.

Fitment & Compatibility

• Exact models: Compatible only with Mammotion LUBA Mini AWD Series 800 and 1500. Not for full-size LUBA AWD or other robotic mowers.
• What’s in the box: 7 complete blade discs (each with a blade set), plus 7 spare blades (total 14 blades). Each disc has 2 blades.
• Measurements: Disc diameter is 4.5 inches (same as OEM). Blade length is 2.2 inches. Confirm your mower’s disc mounting hole pattern matches (center hole with 2 offset pins).
• OEM vs aftermarket: This is a third-party set, not Mammotion branded. Check that your existing discs use a similar 2-pin locking mechanism.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a T20 Torx bit and a small flathead screwdriver to release the pin clips. Watch a video guide first—the pin alignment can be tricky.
• Quality: Blades are slightly thicker than OEM, which may improve durability but also increases vibration if not balanced. Some users report the discs warp after heavy use on rocky lawns.
• Common gotcha: The included screws are slightly shorter than OEM. If your mower has heavy grass buildup under the deck, the screws may not fully thread. Clean the deck thoroughly before installing.
• Performance: The extra blade set gives you 7 total discs (factory has 6), which can improve cutting width by about 1 inch. But this also adds weight and may reduce battery runtime by 5–10%.

Should You Buy It

Buy this if you own a LUBA Mini AWD 800 or 1500, want to increase cutting width slightly, and are comfortable with a moderate DIY install. Skip it if you have a full-size LUBA, prefer OEM reliability, or need a drop-in replacement with zero tweaking—the shorter screws and potential imbalance make it a better fit for tinkerers than casual users.
