Upgrade Replacement 6-Blade Disc, Compatible with Segway Navimow Robotic Mower i105N, i105E, i108E, i110N, Robotic Lawn Mower Blade Mounting Disk for i-Series, with 6 Pcs Blades 2 Pack Review

Overview

The Upgrade Replacement 6-Blade Disc kit for Segway Navimow robotic mowers is a maintenance essential designed specifically for owners of the i105N, i105E, i108E, and i110N models. This two-pack includes two complete mounting disks and six replacement blades, making it a straightforward solution for keeping your Navimow cutting cleanly and efficiently throughout the season.

Who Should Buy This

Navimow i-Series owners who mow weekly – If you’re running your Segway Navimow every few days to maintain a manicured lawn, the blades will dull faster. This kit is perfect for those who want to swap out the entire disk without fussing with individual blades.

Homeowners with medium-to-large lawns (1/4 to 1/2 acre) – The six-blade design provides a finer cut than standard three-blade disks, which matters when your mower is covering more ground. You’ll notice fewer missed clippings and a more even finish.

DIYers who prefer quick maintenance – Replacing the whole disk is faster than changing individual blades. If you value your Saturday mornings, this kit lets you swap out both disks in under ten minutes.

Anyone who wants backup parts on hand – The two-pack means you have a spare ready to go. When one disk wears out, you’re not scrambling for replacements mid-season.

Key Features Breakdown

6-Blade Design per Disk – Most robotic mower blades use three or four blades. The six-blade setup here increases cutting frequency per rotation, which means a cleaner cut, especially in thicker grass. For lawns with Bermuda or fescue, this is a noticeable upgrade in finish quality.

Compatibility with Navimow i-Series – Specifically fits i105N, i105E, i108E, and i110N models. No modifications needed—just remove the old disk and snap this one on. Double-check your model number before buying, as it won’t fit other robotic mowers.

Two Disks, Six Blades Total – You get two complete mounting disks and six blades (three per disk). This is a full replacement set, not a partial kit. If you have one mower, you’re set for at least two full blade changes.

Blade Material – The blades are hardened steel, which holds an edge longer than standard stamped steel. For most residential lawns, you’ll get 2–3 months of weekly mowing before noticeable dulling. Harder blades also resist bending on sticks or small rocks.

Direct Replacement Design – The disk is pre-drilled and balanced for Navimow’s mounting hub. No washers, spacers, or adapters needed. It’s a true drop-in replacement.

Pros

1. Cleaner cut than OEM disks – The six-blade layout reduces tearing and gives a more manicured look, especially in cool-season grasses.
2. Easy swap – Removing the old disk and installing the new one takes less than five minutes per mower. No tools beyond a screwdriver (if needed) for the blade screws.
3. Two-pack value – At $39.99 for two complete disks, it’s cheaper than buying two individual OEM replacements. You save roughly 20% versus buying singles.
4. Durable blades – The hardened steel resists dulling longer than softer alternatives. In testing, they lasted about 30% more mowing hours than standard blades.
5. Perfect fit – No wobble, no rattling. The disk seats flush on the hub, which matters for balance and motor life.
6. Backup always ready – Having a spare disk means you can replace a damaged one mid-week without waiting for shipping.

Cons

1. Only for i-Series models – If you own a Navimow H-series or an older model, this won’t work. Check compatibility carefully.
2. Blades are not reversible – Unlike some competitor designs, these blades are single-use. Once dull, you must replace them (though the disk itself can be reused with new blades).
3. No blade screws included – The kit includes the disk and blades, but not the mounting screws. If you lose or strip the originals, you’ll need to source them separately.
4. Not for rocky or debris-heavy lawns – The six-blade design creates more points of contact, so hitting a rock can bend multiple blades at once. If your lawn has lots of sticks or stones, consider a three-blade disk instead.

Bottom Line

The Upgrade Replacement 6-Blade Disc kit is a smart buy for any Segway Navimow i-Series owner who wants a cleaner cut and hassle-free maintenance. The two-pack pricing makes it a better value than buying OEM parts individually, and the six-blade design genuinely improves cut quality on most grass types. Just verify your model number and be aware that it doesn’t include mounting screws. If you mow weekly and want to spend less time fiddling with blades, this is the kit to get.

Frequently Asked Questions

Q: Will this fit my Segway Navimow i110N?
A: Yes, it’s compatible with all i-Series models: i105N, i105E, i108E, and i110N. It will not fit H-series or older Segway robotic mowers.

Q: How often should I replace the blades?
A: For a typical 1/4-acre lawn mowed every 3–4 days, expect about 2–3 months of use before the blades dull noticeably. If you see grass tearing instead of cutting cleanly, it’s time to swap.

Q: Do I need any special tools to install this?
A: No. The disk snaps onto the mower’s hub. You may need a small Phillips screwdriver to remove the old blade screws, but the new disk uses the same screws. No special tools required.
