    Assembly

    Installation recommendation - PREMIUM knife blade system

    Our installation recommendations serve as a non-binding guide. If different, the manufacturer's specifications take precedence.

    Required tools, aids and protective equipment:

    • Hexagon key 3mm - optionally with our cool bit holder
    • Cut-resistant gloves

    Assembly process:

    1. Pre-positioning: Insert the hole in the knife blade into the collar of the knife blade screw. Ensure correct guidance and centering.
    2. Attach: Position the pre-positioned screw and cutter blade on the threaded sleeve
    3. Continuation: Repeat steps 1 & 2 until the assembly is complete
    4. Screw connection: Tighten all screws evenly with a moderate torque (approx. 1 Nm).
    5. Check: Check that the knife blades can move freely so that they can swing and are not jammed by the screw
    6. Countercheck: Lateral view to ensure that the knife blades are guided through the collar

    PREMIUM blade replacement in used condition:

    1. Pre-cleaning1: Clean the blade disc with a light jet of water without high pressure in accordance with the manufacturer's instructions. This is used for regular cleaning and to soak away encrusted residues.
    2. Positioning: Place the robotic lawnmower securely in the maintenance position.
      Alternatively: Remove the blade disc for better accessibility.
    3. Pre-cleaning2: Use our dirt scraper to remove coarse dirt residues from the hexagonal profile of the knife blade screws. This makes it easier to loosen the screws.
    4. Disassembly: Loosen all screws and remove the old blades. Hold the blade plate in a secure position to prevent it from turning.
    5. Pre-positioning: Insert the hole in the knife blade into the collar of the knife blade screw. Ensure correct guidance and centering.
    6. Attach: Position the pre-positioned screw and cutter blade on the threaded sleeve
    7. Continuation: Repeat steps 5 & 6 until the assembly is complete
    8. Screwing: Tighten all screws evenly with a moderate torque (approx. 1 Nm).
      Tip: Hold the knife blades in the collar of the screw while tightening
    9. Check: Check that the knife blades can move freely so that they can swing and are not jammed by the screw.
    10. Countercheck: Lateral view to ensure that the knife blades are guided through the collar.

    KNIFE BLADE SYSTEMS:

    Image is loading:

    Conventional systems do not have a reliable screw lock, which means that screws can loosen over time due to vibrations. This not only reduces efficiency, but also poses a significant safety risk.

    There is also a lack of effective corrosion protection, which means that the blades rust quickly and lose their sharpness.

    Scratched surfaces and unclean punching are not uncommon and impair cutting performance.

    The lack of a threadless screw attachment makes installation more difficult and increases the risk of damaging the threaded sleeve.

    Another drawback is the unnecessarily high design, which not only creates additional resistance, but also increases energy consumption and reduces the efficiency of the mowing system.

    Image is loading:

    Our CLASSIC knife blade system impresses with its consistent further development. In this respect, we rely on high-quality materials and high-quality workmanship.

    The captive screw lock ensures a stable hold and prevents components from coming loose due to vibrations.

    Thanks to the high-quality special coating, the system is optimally protected against corrosion and retains its sharpness over long periods of time.

    Precise punching and a flawless surface ensure high sharpness and low resistance.

    The improved threadless screw shank enables precise tapping without damaging the threaded sleeve.

    Image is loading:

    Our innovative PREMIUM knife blade system sets new standards in precision, efficiency and durability.

    As our own development, the blade and screw concept has been revolutionized, rethought and perfected down to the last detail. Thanks to the innovative design, resistance has been minimized and aerodynamics optimized. The result: maximum cutting performance, a longer service life and a noticeable reduction in noise.

    At the same time, we have adopted the proven strengths of our CLASSIC system: The captive screw lock, the threadless shank, the high-quality materials and the corrosion-resistant coating.

    Better than the original

    The blades and mounting screws are simply much better than the original from Dreame. If you want to get the full potential out of the Dreame, there's no getting around the accessories from ZTTLPRINT - it's simply worth it!!!

    Fascinating

    I have now been using these blades for a few weeks in conjunction with the Evolution MK4 performance knife plates designed for this purpose and I am absolutely delighted with them. Even the installation is much easier than with the original Mammotion blades, as no additional plastic washers are required. This is simply easier because the blades are already fixed in place by a shank in the mounting screw. Really very well thought out and convincing.

    The background noise is also much more pleasant in combination with the aforementioned blade plates. The cutting pattern itself is absolutely clean and really leaves nothing to be desired. The blades also do not stick to the discs due to the special way they are mounted. Even after mowing in damp grass in the morning, all blades were free and easy to move. The service life of the blades has also been very good so far, still cutting as cleanly as the first cut. I for one will definitely not be buying any other blades. Keep up the good work!

    FAQ - frequently asked questions

    - Woran erkenne ich meine MK-Messsertellergeneration?

    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!

    - Kompatibilitätsübersicht: Messerteller & Messerklingensystem

    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.

    - Wie oft sollten die Messerklingenklingen gewechselt werden (Wechselintervall)?

    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.

    - Müssen die Messerklingenschrauben nach dem Ausbau ersetzt werden?

    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.

    - Ist es normal, dass die Messerklingenschrauben sich schwer einschrauben lassen?

    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.

    - Warum verwendet ihr keine starren Klingen?

    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.

    - Wie ist die Geräuschentwicklung bei der neuesten Messertellergeneration?

    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.

    - Die Messerklingen berühren sich untereinander. Führt dies zu Problemen?

    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.
