Description
The LUBA is an all-wheel mower—and you can tell with its mowing deck. Where other robots turn around at the slope edge, the LUBA keeps going, through taller grass and over uneven ground. This mowing disc is made for this level of stress: balanced, with pre-installed stainless steel blades, suitable for LUBA 1 AWD 1000, 3000, 5000 and LUBA 2 AWD up to model year 2024.
Why the LUBA is harder on the mowing deck
All-wheel drive means: The robot stops less often and covers areas that a two-wheel mower leaves out—slopes up to 38 degrees, damp low spots, and dense transition zones to the flower bed. Each of these trips costs blade sharpness.
There’s also the area requirement. A LUBA 2 AWD 5000 is designed for 5,000 m² and therefore runs for a long time in one go. The blades cover many times the distance compared to what a small garden robot ever sees.
The disc itself is not a wear part—the blades are. That’s why we supply it pre-fitted and swappable: If you upgrade later, you only replace the cutting edges.

Which Mammotion do I have?
Mammotion offers three series in parallel, and the names are very similar. If you’re unsure, you can find the differences here—just unfold to see them.
Change without a workshop visit
- Switch off LUBA and remove it from the charging station—not just pause it.
- Put on gloves and lay the robot on its side.
- Detach grass felt and soil residue from the mowing deck; especially with the AWD, quite a bit collects there.
- Unscrew the old disc, attach the new one, and tighten evenly.
- Turn it by hand: The disc must run freely, without scraping.
Five minutes, a screwdriver. The only thing that matters is tightening evenly—an incorrectly seated disc creates imbalance, and the mowing motor carries that imbalance throughout the entire season.

6, 7 or 9 blades for the LUBA
With the all-wheel mower, the number of blades matters less for cutting performance than for service life. More cutting edges share the same work—resulting in a finer cut pattern, but each individual blade lasts for a shorter time.
6 blades – the robust choice with cover
The configuration with which LUBA is supplied. For large areas with tall or damp grass, it is the most durable option: fewer cutting edges mean more material per blade and therefore longer service lives.
In addition, it includes a component that the other two variants don’t have: a closed cap over the center of the mowing disc. With LUBA, this isn’t just cosmetic—when an all-wheel mower turns on soft ground, it pushes soil and clippings under the chassis, and that material would otherwise wrap around the blade mount. The cap keeps the area covered, allowing the blades to continue running freely.
On 3,000 m² and more, this adds up: every cleaning stop means bringing the robot out, turning it around, and scraping the mowing area clear. That’s usually avoided here.
7 blades – the middle way
One cutting edge more for a noticeably more even cutting pattern, with hardly any measurable increase in wear. The most sensible option for well-kept lawns with normal growth height.
Especially on slopes, this pays off: there, the LUBA mows in lanes with greater overlap, and finely cut material decomposes faster.
For context: The middle cap is reserved for the 6-blade version. If you mow your property mostly when the ground is dry, you’ll hardly notice it—on heavy, damp ground, the 6-blade disc is the easier-to-maintain option.
9 blades – decorative lawn setup
The densest variant is worth it if LUBA runs every day and the lawn is kept short. The cut pattern then becomes visibly more even, and individual blades that are left behind disappear.
On large natural areas with overgrowth, however, it’s the wrong choice—there, nine thin cutting edges dull faster than they provide any benefit.
When the mowing disc is due
Buy blades individually
With LUBA, the blades are the wear part—the mowing disc lasts significantly longer. If you mow large areas, the 60-blade replacement set including screws keeps you stocked for several seasons at home—and you won’t have to wait for a delivery the next time you change them.
