Luba - Set of Sealing kit

Replace the bulky OEM metal side guards (the “cages”) under your Mammotion Luba's cutting discs with a slim seal that mounts right on the spindle. You lose the grass-trapping cages, keep the spindle and motor sealed against grass and moisture — and because the cages overlap the cutting discs, removing them even gains you a little extra cutting width.

🔧 About the kit

The Luba's factory metal guards bolt to the chassis underneath the robot, around each cutting disc, with their mounting points hidden beneath the disc. They shield the spindle area but readily trap grass, and they overlap the edge of the cutting disc. Remove the cutter disc and the guard, and the rubber gasket that seals the spindle and motor is exposed. The sealing kit bolts back at those same mounting points as a low-profile ring sitting on the gasket — sealing the spindle without the bulk of the cage. Sold as a pair, one per disc.

🛠️ Installation: remove the cutting discs to reach the mounting points, fit the seals on the spindle, then refit the discs.

🔄 Version guide

Low-Profile (2023–2025) — the slim version with extra clearance. Newer Luba cutting discs have teeth on their underside that collide with a taller seal, so these discs need the low-profile ring. Choose this if your discs have underside teeth.

Extended Seal (2023–2024) — the original, taller seal for 2023–2024 discs without the underside teeth.

✅ Benefits

• Removes the bulky OEM metal guards that trap grass under the robot
• Seals the spindle and motor against grass and moisture
• Slightly increases effective cutting width — the cages overlap the discs, so losing them frees a little more cut
• Cleaner underside and easier maintenance
