Ultimow Carbon Fiber LUBA 6-Blade Disks (pair) review

The quick answer

Ultimow’s Carbon Fiber 6-Blade Disks are a pair of replacement cutting disks for Mammotion LUBA robot mowers (not the Mini). They use PA6-CF carbon fiber nylon, titanium-plated diamond blades and Phillips head screws, ship fully assembled and weigh 25% less than the original disks, according to Ultimow. Choose them to replace worn or blade-sticking stock disks.

Ultimow says orders are projected to resume shipping in late October or early November 2026.

Why we like these disks for LUBA owners

The stock disks on a robot mower are a wear item, and stuck or damaged blades are the common frustration. Ultimow’s disks are made from PA6-CF carbon fiber nylon, ship assembled with six titanium-plated blades each and, per Ultimow, weigh 25% less than the originals. That makes them a simple, low-cost refresh for an owner who wants cleaner cutting and easier blade changes.

Check the fit first

Ultimow guarantees fit for LUBA 1, 2, 2X and 3, excluding the Mini. If you own a LUBA 2 AWD, confirm your exact variant with Ultimow before ordering. Remove the old disks following Mammotion’s guidance, and use threadlocker on the mounting screws as Ultimow recommends.

Blades and everyday care

The diamond-shaped blades are titanium-plated and held with Phillips head screws, so swapping a worn blade needs no special tool. Ultimow also sells replacement blades. Inspect the blades regularly, because a loose or damaged blade is a safety issue; switch the mower off before touching the disks.

What to know before you buy

Ultimow’s claims that the disks resist sticking and survive impacts come from its own testing and we have not tested them. The product page says shipping is projected to resume in late October or early November 2026, so expect a wait. The listing excludes the LUBA Mini, and you are fitting the part yourself.

Our buying advice

Buy these if your stock LUBA disks are stuck, worn or damaged and you are comfortable fitting them. Ultimow lists the pair at $105, and its partner program reports 5% off with SEBASTIANBASSOL, which would bring it to about $99.75 if it applies; confirm the total at checkout because eligibility has not been verified.
