The FourShow 6-Blade Disc is an upgrade cutting component designed specifically for Segway Navimow robotic lawnmowers, including the i-Series (i105N, i108N, i110N) and AWD models (i206, i210). This replacement disc is ideal for owners who want to improve their mower's cutting efficiency and achieve a more manicured lawn without replacing the entire mower.
Standout features include six titanium blades instead of the standard three, which significantly reduces wear on each blade and delivers a more consistent, beautiful cutting pattern. The additional blades also improve mower smoothness, meaning less vibration and quieter operation while trimming grass. Users can expect a noticeable upgrade in lawn quality, especially on larger or more demanding yards.

The stainless steel screw holder is directly overmolded into the injection mold, ensuring a secure grip and preventing screws from loosening over time. The package includes six titanium blades and screws, making installation straightforward.
One potential drawback is the lack of verified customer reviews, so long-term reliability is unproven. Additionally, the disc is only compatible with Segway Navimow models, limiting its use for other brands. The price is slightly higher than standard discs, but the added blades and robust construction justify the cost for those seeking performance.
Overall, the FourShow 6-Blade Disc is a well-engineered upgrade for Navimow owners who want a smoother, more efficient cut. Its durable materials and complete package make it a convenient choice. If you prioritize lawn appearance and mower longevity, this disc is worth considering.
Buying Guide
Compatibility with Your Navimow Model
Before buying any cutting disc, verify it fits your specific Navimow model. Discs designed for the i-series (like i105N, i110N) often differ from those for the H-series (H1500N, H3000N-VF). Some discs claim broad compatibility, but we recommend double-checking the specifications listed by the manufacturer. A mismatch can cause poor cutting or even damage to your mower.
For example, FourShow [Upgrade 6-Blade Disc Compatible works specifically with H-series models, while KuddinX – Titanium Blade Disc 6-Blade Assembly is tailored for i-series. If you own an older model like I105E or I108E, look for discs explicitly stating that compatibility, such as the GGERWEqgj or SHAOMABA options.
Material and Durability
The disc material directly affects longevity and cutting quality. Most premium discs use reinforced polyamide nylon (PA6) with glass fiber or high-strength PETG. These materials resist warping and cracking under stress. Avoid discs made from basic plastics, as they may degrade quickly. The FourShow and KuddinX discs both use PA6 and glass fiber, offering excellent durability for regular mowing.
Blade Configuration
Cutting discs come with different blade mounting points: 4-blade, 6-blade, or 12-blade setups. More blades generally mean a finer cut and less stress on each blade, but they also increase weight. For most Navimow models, 6-blade discs strike a good balance between cut quality and battery efficiency. Some discs, like the 2Pack Replacement Cutting Disc for Navimow Robotic, support both 4 and 6 blades, giving you flexibility.
Included Components
Some replacement discs come as a complete kit with titanium blades and screws, while others include only the disc itself. If you need to replace blades too, a kit like the FourShow or KuddinX saves time and ensures compatibility. For discs that don’t include blades, you need to purchase them separately. Consider your mower’s current condition—if blades are worn, a full kit is more cost-effective.

Final Thoughts

Both options have been verified for quality and will help you achieve a beautifully manicured lawn throughout the season.
Frequently Asked Questions
How often should I replace my Navimow cutting disc?
We recommend inspecting the disc every three to six months, depending on usage. If you notice uneven cuts, excessive vibration, or visible wear on the disc, it is time for a replacement. Regular maintenance extends the life of your mower.
Can I use a 6-blade disc on an i-series Navimow that originally had 4 blades?
Yes, many aftermarket discs like the FourShow and KuddinX options are designed as direct upgrades. They typically include the necessary screws and maintain compatibility. However, always check the product description to ensure your specific model is listed.
What material is best for a Navimow cutting disc?
Polyamide nylon reinforced with glass fiber (PA6+GF) is a top choice for its strength and durability. PETG is also good but may be less impact-resistant. Avoid generic plastic discs that may warp under load.
Do I need to replace blades when I replace the disc?
Not necessarily, but if the blades are worn or damaged, it is a good idea to replace them together. Kits that include both disc and blades simplify the process. For more blade maintenance tips, see our article on the best robot mower blade sharpener.
