This assumption is an overgeneralization. The robustness of 3D printing begins with the careful selection of the material. A cutting disc made from high-impact polymers like ASA can exhibit adequate impact resistance even under high loads, such as contact with solid objects. The rotational speed of nearly 3000 revolutions per minute leads to significant forces upon sudden obstacles, which are proportional to the mass of the rotating components, making material selection crucial to absorb these forces.
Impact resistance is a particularly important property for materials used outdoors in mower discs. ASA is known for its good impact resistance, even at low temperatures. Compared to other plastics like PLA, PETG, and ABS, ASA offers superior benefits regarding impact stress.
These properties make ASA a preferred material for applications requiring high impact strength, such as in the automotive industry, construction, or sports equipment exposed to frequent shocks and blows. ASA's ability to maintain its integrity and performance under these conditions makes it an excellent choice for outdoor use.
Innovative construction possibilities through 3D printing:
3D printing revolutionizes manufacturing technology through its ability to create complex structures not possible with traditional methods like injection molding. A significant advantage of this technology is the possibility to realize highly stable structures while saving material and weight through targeted design and the use of Finite Element Methods (FEM).
Material economy and structural integrity:
A vivid example of the principle of material economy is the comparison between an I-beam and a solid beam with a rectangular cross-section. The I-beam, known in the construction industry for its high bending stiffness and load-bearing capacity, uses material more efficiently by concentrating mass where it contributes most to load-bearing capacity – far from the neutral axis. This principle can be applied to 3D printing, where mechanical properties can be optimized by integrating hollow spaces and specific wall thicknesses.
FEM analysis for optimization:
FEM analysis supports this process by simulating the resilience and behavior of structures under load conditions to adjust the design accordingly. This results in components that offer high strength and stability at reduced weight. The ability to targetedly use hollow spaces allows for the creation of lightweight yet highly stable structures suitable for demanding applications.
Summary of benefits:
In summary, 3D printing offers the advantage over injection molding that it enables high structural stability with optimized material usage through the integration of hollow spaces and the application of FEM analyses. This leads to lightweight but extremely resilient components designed for demanding applications. 3D printing utilizes the principle of material economy, similar to an I-beam, to achieve higher load capacity with less material.

More blades improve the cutting pattern and mulching effect as they cut the grass more finely. The load is distributed across more blades, extending their lifespan. Physically speaking, arranging the blades at the edge of the mower disc increases the moment of inertia, leading to a more stable rotational movement and fewer disturbances. This results in smoother running and improved synchronization.
For dense lawns or deep cuts, a higher number of blades may be necessary to ensure an even cutting pattern.

Intended Use:
Our products (mowing discs, adapters, blades, screws) are designed exclusively for use in compatible robotic lawnmowers as specified on the respective product page. Since our performance mowing discs may allow for a wider cutting width and/or a different cutting height compared to the original part depending on the model, special application instructions apply. Any other use is considered improper.

1. Important Safety Warnings

Risk of cuts: This product contains or is used with extremely sharp blades. It is mandatory to wear protective gloves during assembly and maintenance.
Danger to children: Small parts (screws, adapters) can be swallowed (choking hazard). Sharp blades can cause severe injuries. Keep all components out of the reach of children.
Regular inspection: Please check the mowing disc, screws, and blades for a tight fit, cracks, or damage before each use. Replace defective parts immediately.

2. Preparation & Application

Remap the lawn area: If the new mowing disc has a larger cutting width or a different cutting height than the original, the robotic lawnmower must absolutely be remapped. This is the only way to ensure sufficient distance to edges and obstacles is maintained.
Check the lawn before each mowing process: Carefully inspect your lawn for obstacles such as stones, branches, roots, toys, manhole covers, sprinklers, or severe unevenness in the ground.
Protective function (predetermined breaking point): If blades hit solid obstacles at high speeds, massive forces are exerted. Our discs are designed to break under exceptionally strong impacts (predetermined breaking point) to protect the motor, shaft, and bearings of your robotic lawnmower from expensive total damage. Damage caused by obstacles does not constitute a quality defect.

3. Assembly & Installation

Disconnect from power: Turn off the robotic lawnmower completely before any assembly.
Manual clearance check: It is mandatory to slowly rotate the newly mounted mowing disc by hand once before turning it on for the first time. Check carefully whether the disc or the extended blades rub or hit the housing, the blade guard, or the wheels at any point. The disc must rotate completely freely without touching anything. Only operate the robotic lawnmower if this absolute clearance is guaranteed.
Tighten hand-tight only: Use only a manual screwdriver for all screws (blade and adapter assembly).
⛔ ATTENTION: The use of cordless screwdrivers or power tools is not permitted! Excessive torque will destroy the material or the threads.

4. Material-specific Instructions & Disposal

ASA material: Heat-resistant up to approx. 80 °C.
Personal responsibility: Careful preparation of the lawn and correct setup of the robotic lawnmower contribute significantly to safe operation. Damage caused by improper use or foreign objects in the lawn is not covered by the warranty.
Disposal: Dispose of blades safely packaged. Please recycle the packaging.

Disque avec 9 lames pour robot tondeuse Worx WR341E, le top !

J'ai acheté un disque pour mon robot tondeuse Landroïd vision Cloud Worx WR341E, équipé de 9 lames (au lieu de 3 lames d'origine). Le montage du nouveau disque n'a posé aucune difficulté, 3 vis à remettre. La conception des lames permettent de les retourner, la qualité de l'ensemble est au top !

Deutlich besseres Schnittbild, hochwertige Klingen und überzeugende Qualität – klare Empfehlung!

Kurzum vorweg: Ich war anfangs wirklich unsicher, ob ich dieses Produkt überhaupt brauche. Eigentlich war ich mit dem originalen Mammotion-Mähteller und den fünf Klingen zufrieden.

Ich selbst nutze einen YUKA Mini 500, den ich zusätzlich mit dem großen 6,1-Ah-Akku ausgestattet habe. Schon vorher war das Schnittbild für mich grundsätzlich okay, allerdings fiel mir auf, dass die Grasspitzen teilweise etwas „abgeschlagen“ wirkten und dadurch weiße Spitzen entstanden.

Nach dem Wechsel auf den Mähteller von greengear war ich tatsächlich überrascht: Mittlerweile sehe ich praktisch keine ausgefransten bzw. weißen Grasspitzen mehr. Die Halme wirken deutlich sauberer geschnitten und auch an den Kanten sieht das Ergebnis wesentlich ordentlicher aus. Insgesamt macht der Rasen dadurch einfach einen saubereren und hochwertigeren Eindruck. 👍

Einen Punkt sollte man allerdings berücksichtigen: Die höhere Anzahl an Klingen macht sich bei meinem YUKA Mini auch beim Energieverbrauch bemerkbar. Der Mähteller benötigt offensichtlich etwas mehr Leistung als das Original. Mit dem ursprünglichen Teller war der Akku nach dem vollständigen Mähen meiner Fläche normalerweise noch nicht annähernd leer und ein Zwischenladen war nicht erforderlich. Mit dem neuen Teller kann es dagegen durchaus vorkommen, dass der YUKA zwischendurch noch einmal zur Ladestation fahren muss bzw. am Ende mit deutlich weniger Restkapazität zurückkommt.

Ich bin deshalb froh, meinen YUKA Mini bereits auf den großen 6,1-Ah-Akku umgerüstet zu haben. Wer eine größere oder anspruchsvollere Fläche mäht, sollte den zusätzlichen Energiebedarf meiner Meinung nach im Hinterkopf behalten. Für mich ist das allerdings ein nachvollziehbarer Kompromiss: Mehr Klingen und ein sichtbar besseres Schnittbild benötigen eben auch etwas mehr Leistung.

Auch bei der Qualität muss sich das Produkt meiner Meinung nach nicht hinter dem Original verstecken. Natürlich handelt es sich beim Teller um ein 3D-Druck-Bauteil, allerdings keineswegs um eines minderer Qualität. Festigkeit und Stabilität machen auf mich bislang einen sehr guten Eindruck.

Fast noch interessanter finde ich allerdings die TiC/TiN-beschichteten Klingen. Mammotion setzt beim Original auf klassische Edelstahlklingen. Bei meinen originalen Klingen konnte ich mit der Zeit beobachten, dass sich insbesondere im Bereich von Schmutz- und Grasanhaftungen kleine oberflächliche Roststellen bzw. Verfärbungen bildeten.

Die goldfarben beschichteten Klingen von greengear machen hier bislang einen deutlich unempfindlicheren Eindruck. Trotz Grasresten und Anhaftungen konnte ich bisher keine vergleichbaren Veränderungen feststellen. Ich erhoffe mir dadurch natürlich auch eine entsprechend lange Standzeit der Schneiden – das wird sich im Langzeittest noch zeigen. 😉

Auch die Kommunikation verdient ein Lob. Ich hatte einige Rückfragen, die sehr schnell und kompetent beantwortet wurden. Gleichzeitig habe ich noch eigenes Verbesserungspotenzial angesprochen, welches offen aufgenommen wurde. Genau so stelle ich mir den Kontakt zwischen Hersteller und Kunde vor.

Unterm Strich bin ich mit dem Produkt wirklich sehr zufrieden. Das Schnittbild meines YUKA Mini hat sich sichtbar verbessert, die Verarbeitung überzeugt und auch der Kontakt war hervorragend. Der etwas höhere Energiebedarf ist für mich angesichts des deutlich besseren Schnittbildes absolut vertretbar.

Von mir daher ganz klar: ⭐⭐⭐⭐⭐ – gerne weiter so!

The decision to use an odd number of blades is based on engineering principles derived from aircraft and mechanical engineering in order to minimize resonance frequencies. Symmetrically opposed blades can induce resonance phenomena, while odd numbers help to distribute the resulting forces and vibrations more homogeneously. Furthermore, the probability of imbalance, which can be caused by adhesion of grass clippings, is reduced with an odd number of blades.

This assumption is an overgeneralization. The robustness of 3D printing starts with the careful selection of the material.

Rigid blades pose risks, especially for low material thicknesses (under 0.5 mm). They can break on contact with solid objects and act as dangerous projectiles. The direct power transmission to the drive and bearing on impact can cause damage and increased wear, which shortens the lifespan of the mowing robot. In contrast, pivoting blades
reduce the impact forces and are better suited to most lawns.

Multiple blades improve the cutting pattern and mulching effect as they cut the lawn more finely. The load is distributed over more blades, which extends their service life. Physically, the arrangement of the blades at the edge of the mower disc increases the moment of inertia, resulting in a more stable rotational movement and less interference. For dense lawns or deep cuts, a higher number of blades may be necessary to ensure a uniform cutting pattern.
