Description
The YUKA Mini works with a floating-mounted cutting deck – the disc follows the ground profile instead of rigidly scraping over unevenness. This protects the lawn, but it also places demands on the disc: it must be cleanly balanced, otherwise every imbalance is transferred directly to the suspension. This disc fits the entire Mini family – YUKA Mini 500 to 800 and YUKA Mini 2 500, 800, 1000, including the LiDAR versions.
Why balancing matters for the YUKA
Unlike mowing decks that are rigidly mounted, the disc on the YUKA Mini is mounted so it can move. When the robot drives over a bump in the ground, the entire mowing deck tilts upward and then settles back into place. The result is an even cut even on uneven terrain.
The downside: A poorly balanced disc has more room to start vibrating. What on a rigid mowing deck only produces a hum becomes noticeable shaking with floating mounting—and puts strain on the suspension.
We manufacture the mowing discs as a matched set and supply them with blades already installed. During installation, you don’t need to readjust anything—just tighten them evenly.

YUKA Mini or LUBA MINI?
Hardly any question is asked more often at Mammotion. Both devices are compact, cost about the same, and are often shown side by side—the difference lies in the drive.
Replacement on the YUKA Mini
- Switch off the robot using the button, not just pause it.
- Put on gloves and carefully lay the device on its side.
- Clean the mowing deck of grass residues—the floating deck can be lifted easily for this.
- Loosen the screws, remove the old disc, attach the new one, and tighten in a cross pattern.
- Turn the disc by hand and tap each blade: it must be able to move freely around its screw.
Tightening in a cross pattern is more important here than with fixed mowing decks—this ensures the disc sits flat and the floating bearing is able to work as intended.

6, 7 or 9 blades on the YUKA Mini
With a 190 mm cutting width, the YUKA operates in narrow lanes and overlaps accordingly often. Each blade of grass is therefore hit multiple times—the number of blades determines less the power and more the fineness of the cut.
6 blades – factory configuration with protective cap
The direct replacement for the original cutting disc: same configuration, same running behavior, no adjustment needed for the robot.
This version is the only one with a cap over the center of the mowing disc—it is not available with 7 or 9 blades. On the YUKA, it plays a special role because the floating mowing deck, when lowered, pushes cut material inward. Without a cap, it collects around the blade mounting; with the cap, the area remains accessible and the blades rotate freely.
For anyone who maintains the lawn normally and wants to simply let the robot run, this is the easiest option to care for.
7 blades – denser cutting pattern
One more cutting edge on the same disc. With YUKA’s narrow mowing lanes, this adds up quickly: the grass is hit more often with each overlap, and the cut becomes shorter and more even.
Ideal for well-kept ornamental lawns and regular mowing intervals of two to three days.
Without center cap: On dry, level lawn, this makes no difference. If you frequently run the YUKA over wet grass, you should choose the 6-blade version.
9 blades – for daily operation
The densest blade setup is worth it when the YUKA runs practically every day and only trims the tips. This creates a very uniform cutting pattern in which individual blades that remain standing are hardly noticeable.
With longer mowing breaks or tall grass, the advantage is reversed: nine narrow cutting edges distribute the same work across more edges and therefore dull earlier accordingly.
Also here without a center cap – in practice, for daily operation on dry lawn, this is not an issue.
Time for a new disc?
Buy blades individually
Because with YUKA the entire set of blades should always be replaced, it’s especially worth keeping a supply. The 60-blade replacement set with screws is enough for many swaps—and the next set is already on hand when the lawn needs it.
