Segway Navimow H-Series robotic lawnmower Performance blade disc EVOlution MK4 orange

Mit der Einführung unseres neuen Shops am 12.03.2025 haben wir auch die nächste Generation unserer Messerteller veröffentlicht: MK4.

Damit wurde nicht nur ein weiterer technologischer Meilenstein gesetzt – erstmals ist damit auch die komplette Kompatibilität zu unserem eigenentwickelten PREMIUM-Messerklingensystem gegeben.

Alles davor, also MK1 – MK3, ist ausschließlich mit unserem CLASSIC-Messerklingensystem kompatibel.

Was bedeutet MK eigentlich?
„MK“ stammt aus dem Englischen und steht für „Mark“ – also die jeweilige Entwicklungsstufe bzw. Generation unserer Performance-Messerteller.

Jede Stufe steht für eine klare Weiterentwicklung in Design, Technik und Performance.

Wo erkennst du die Unterschiede?
Die Unterschiede zwischen MK1 – MK4 zeigen wir dir im Shop übersichtlich mit Vergleichsbildern.
Außerdem erkennst du die MK-Stufe direkt am Produktnamen, in der Artikelbeschreibung oder in der Bestellung.

If you have any questions, our support team will be happy to help you at any time!

Die folgende Übersicht zeigt dir auf einen Blick, welche Kombinationen aus Messerteller und Messerklingensystem miteinander funktionieren – und worauf du achten solltest.
Weitere Detailinformationen sowie technischen Daten findest du auf den jeweilingen Produktseiten.

Unsere neuen Performance-Messerteller sind speziell für unser eigenentwickeltes, superscharfes PREMIUM-Messerklingensystem konzipiert – nur diese Kombination garantiert maximale Leistung, höchste Präzision, Funktion und Sicherheit: für einen langanhaltend perfekten Rasenschnitt.
Dank der optimierten Aerodynamik reduziert die spezielle Bauform nicht nur das Betriebsgeräusch, sondern minimiert auch die Reibung und den Widerstand – für noch effizienteres Mähen.

Wir als Hersteller haben uns bewusst dazu entschieden, ausschließlich die Verwendung unserer eigenen, speziell entwickelten CLASSIC- und PREMIUM-Messerklingensysteme zu empfehlen. Diese Kombination wurde von uns geprüft, erprobt und freigegeben – andere Klingen hingegen nicht.
Wir hoffen auf dein Verständnis für diese Entscheidung, die der Sicherheit, Funktionalität und Langlebigkeit unserer Produkte dient.

More cutting performance, more safety, less resistance - with our PREMIUM blade system, you won't make any half cuts!

OEM = Original Equipment Manufacturer (Originalteile der Mähroboter-Hersteller)

Weitere Hinweise zu den jeweiligen Kombinationen:

3) Durch den kleineren Schnittdurchmesser kann es bei Mehrtellersystemen (z. B. Mammotion Luba) – abhängig von der Messertelleranordnung und der Bahnenüberlappung – mittig zu einem ungemähten Streifen kommen.

5) & 6) Die Vielfalt der OEM-Anbindungssysteme – sei es in Länge, Form oder Schraubengeometrie – nimmt stetig zu. Eine allgemeingültige Aussage zur Kompatibilität ist daher kaum möglich.

8) Zur Kompatibilität gehören unter anderem Modelle von Ecovacs, Gardena, Gardena, Husqvarna, Mammotion, RoboUP, Segway, und viele mehr...
Falls Unsicherheiten bestehen, empfehlen wir, die Originalklingen und -schrauben mit unseren technischen Daten abzugleichen.

Ein pauschales Wechselintervall geben wir für unsere Messerklingen bewusst nicht an, da die Standzeit von vielen Faktoren abhängt, so z.B.

• Useful life
• Mowed area completed
• Turf type
• Moisture
• Content and intensity of the sap

A simple and reliable method for determining this is to look at the cutting edges of the lawn.

If these become frayed, this is a sign that the blades are losing their sharpness and should be replaced. This process is gradual, so there is no danger of having totally frayed cutting edges overnight.

In addition, sticky plant sap can build up on the blades during mowing, which impairs cutting performance - even without visible wear. In such cases, cleaning often helps before replacement is necessary.

Basically, the following can be said:
Our PREMIUM knife blade system impresses with super-sharp, long-lasting knife blades and a high number of blades - for a noticeably longer service life compared to the original design.

Ja – zumindest dann, wenn diese bereits einmal vollständig ein- und ausgedreht wurden.Unsere Schrauben sind mit einer vorgebrachten, chemischen Schraubensicherung ausgestattet. Sie verhindert ein selbstständiges Lösen der Schraube im Betrieb und ist damit ein wesentlicher Bestandteil der Sicherheit.

Schrauben mit chemischer Schraubensicherung unterliegen der Norm DIN 267-27 und sind für den einmaligen Gebrauch vorgesehen. Beim Herausdrehen wird die Sicherungsschicht mechanisch beschädigt und verliert damit ihre volle Wirkung.

Grundsätzlich lassen sich Schrauben mit Schraubensicherung etwas schwerer ein- und ausschrauben. Dies gilt für unsere CLASSIC- wie auch PREMIUM-Messerklingenschrauben.
Die Sicherheit hat oberste Priorität – ein fester Sitz sorgt für einen zuverlässigen Halt, um ein ungewolltes Lösen der Schrauben während des Betriebs zu verhindern.

Bei der ersten PREMIUM-Schraubenproduktion hatten wir eine etwas zu hohe Klemmung eingestellt. Mit der Einführung unserer gelaserten Messerklingen haben wir auch die Klemmung der Schrauben nachjustiert und optimiert.
--> Die Schrauben lassen sich seither leichter einschrauben, während der feste Sitz der Klingen weiterhin gewährleistet bleibt. So vereinen wir höchste Sicherheit mit einer deutlich komfortableren Handhabung bei der Montage.

Our conscious decision to dispense with rigid blades is primarily based on one key aspect: safety.

We rely on a sophisticated centrifugal force system with flexible blades that fold out when rotating and immediately give way on contact with solid obstacles. This protects people, animals, the environment and the mower itself. This is an invaluable advantage, especially in gardens with children, pets or sensitive boundaries.

Despite the flexible blades, our performance blade discs achieve outstanding cutting performance in combination with the PREMIUM blade system -clean, precise and efficient. The myth that only rigid blades cut sharply and powerfully is now a thing of the past.

In the context of current safety standards - in particular IEC 60335-2-107 (formerly DIN EN 50636-2-107), which regulates the requirements for the safe operation of robotic lawnmowers worldwide - it is also clear that systems with flexible blades are more likely to meet the desired safety standard than rigid cutting tools.

In short:
Maximum cutting performance with maximum safety - that is our claim.

Thanks to aerodynamic optimizations to the knife blade system and the design of the knife discs, we were able to reduce the noise level to almost the original level despite continuing to use a very high number of knife blades.

The average increase in volume is only a few decibels and is hardly noticed subjectively.

Better sound: Thanks to the maximum cutting performance, mowing no longer sounds strained or "tortured", but smooth and pleasant.

New or freshly inserted knife blades may initially make a rattling noise due to the free swinging of the blades. This is due to technical reasons and disappears after a short period of operation.

Recordings made with cell phones or simple microphones often do not realistically depict the actual sound. Due to overmodulation and a limited frequency range, such recordings often appear distorted or exaggerated in terms of noise level.
A subjective comparison or a realistic assessment is only possible to a limited extent on this basis.

Conclusion: The new MK4 generation of blade discs offers an optimized background noise without compromising performance.

Yes, a change is generally possible.

However, the bit is held in place without a magnet or spring mechanism. This means that the holding force can decrease slightly with each change.

Nevertheless, the bit remains fixed and ready for use even after many changes.

The higher weight of the blade discs results from the increased number of blades and their connections - this is deliberate and intentional. However, this does not automatically lead to higher battery consumption or a greater drive load.
The optimized, aerodynamic design reduces air resistance, while our knife blades with maximum cutting performance minimize cutting resistance.
Rotating components generate a moment of inertia. A higher weight means a greater inertial mass, which can slightly increase energy consumption for a short time during the start-up phase. During regular operation, however, the blade disk speed remains constant. The higher inertia mass compensates for load peaks - for example in denser grass - so that the motor requires less energy to maintain rotation.
In addition, grass clippings can adhere to the blade disc when mowing damp grass. This additional weight corresponds approximately to the difference in weight of our blade discs and also occurs with original parts .
Each robotic lawnmower is also equipped with overload protection, which detects critical load situations and protects accordingly.
Overall, this does not result in any significant disadvantages and none of our long-term tests or numerous feedbacks from the field show any significant differences in energy requirements. On the contrary: in practice, there are often even reports of a positive effect on energy consumption.

Important
The energy consumption of a robotic lawnmower depends on numerous factors, e.g:

• Cutting height (lower height = higher resistance)
• Turf density
• Grass removal per mowing
• Outdoor temperature
• Surface geometry (number of approach cycles, turning maneuvers)
• Terrain profile (gradients, unevenness)
• Lawn moisture
• Firmware version / software version (Mählogik, motor dynamics or energy distribution)

Individual journeys can therefore not be compared objectively.

Yes, our rotationally symmetrical components, such as the rotating blade discs, are regularly tested for imbalance.
The results of our certified service providers confirm that the balance quality of the original parts is not exceeded, even with a higher number of connections. This is achieved and ensured by our design, very dimensionally accurate centring and precise manufacturing.
Testing is carried out in accordance with international and therefore German standards.
Advantage: Minimal imbalance ensures particularly smooth running, reduces centrifugal forces (=centrifugal force) and thus protects the mower.

The quality and appearance of the surface structure is an essential part of our product design.

Layer height:
Our layer heights are optimally selected to ensure a perfect balance between optical quality and mechanical strength.

High-resolution printing technologies:
Thanks to advanced printing processes, precise details and an even surface structure are created.

Quality guarantee:
Our zoomable product images give you a detailed view of the print look and illustrate the high-quality workmanship.

Our products have been carefully developed to remain durable and safe even under increased loads.

High-strength material:
We use UV and weather-resistant thermoplastics, which are particularly robust and durable.

Strength-optimized design:
The construction is specially designed to withstand mechanical loads and ensure reliable performance.

Extensive tests:
In contrast to many other manufacturers, our blade discs undergo long-term practical testing, a centrifugal force test to determine strength and an unbalance test - while the systems of others often remain untested.

No, modern robotic mowers have extensive safety mechanisms, including collision sensors, lifting sensors, ultrasonic sensors, intelligent camera systems and blade stop systems. These functions remain unchanged by our parts and continue to ensure that the blades stop immediately if the robot is lifted or an obstacle is detected.

Minimized risk of injury:
The risk for children and animals in particular is continuously reduced by these mechanisms.
In the case of greatly enlarged blade disc systems, we develop a specifically adapted blade guard. Our blade discs in the Extension series are only available with compatible protective equipment to ensure full safety functionality.

Faster mowing, less time at risk:
More efficient mowing with our parts means that the mowing process is completed more quickly. This reduces the operating time and therefore also the potential hazard duration.

No. During operation, the blades are pushed radially outwards by centrifugal force. This physical property ensures that they are always in a stable position and cannot come into contact with each other on a blade plate.
