Ultimow Carbon Fiber 6-Blade Disks for Navimow X430, X450 and Terranox review

The quick answer

Ultimow's pair of PA6-CF carbon fiber 6-blade disks fits the Segway Navimow X430, X450 and Terranox CM120M1 and CM240M1. The disks ship fully assembled with titanium-plated diamond blades and mounting screws, and the single-layer blade layout makes blade changes quick. Ultimow's US store listed the pair at $120.

Why we like it

PA6-CF carbon fiber nylon, chosen by Ultimow as the strongest material it tested
Six titanium-plated diamond-shaped blades per disk, supplied fitted
Single-layer blades halve the screws to remove and let you change blades without removing the disks
Sold as a pair, with premium mounting screws included
Guaranteed fit for the Navimow X430, X450, Terranox CM120M1 and CM240M1

Before you buy

Fit is specific to the X430, X450 and Terranox models listed, so check your mower before ordering.
Use threadlocker on the mounting screws and the blades, as Ultimow recommends.
Switch the mower off and take care around the blades whenever you handle the disks.

Why we like these disks for a heavy-duty lawn

Blade disks take the hits from roots, stones and toys, and a jammed or cracked stock disk is a common reason a mower stops mid-job. Ultimow's disks are molded from PA6-CF carbon fiber nylon and ship assembled, with six titanium-plated diamond blades on each disk. The diamond shape gives a longer cutting edge and a clean, quiet cut, and the disks are designed so blades rotate freely rather than sticking. They are a practical upgrade for X430, X450 and Terranox owners who mow rough ground.

Easier blade changes

The blades sit in a simple single-layer arrangement, which cuts the number of screws you remove for a blade change in half. You can swap blades without taking the disks off the mower. That turns a routine job into a short one, and it makes it more likely that you keep sharp blades on the mower through the season.

Check the fit first

These disks are made for the Segway Navimow X430 and X450 and the Terranox CM120M1 and CM240M1. Ultimow sells separate disks for the Navimow i series, Mammotion Luba and Yuka, so match the part to your mower. Our [Ultimow Navimow i-series disk review](/reviews/ultimow-navimow-i-series-disk) covers the smaller Navimow range.

Our buying advice and the Ultimow code

Buy these if your stock disks are worn, cracked or prone to jamming and you own one of the listed mowers. The pair is $120, and the price box shows the with-code estimate for SEBASTIANBASSOL.
