Upgrade Replacement 6-Blade Disc, Compatible with Luba & Luba 2 Robotic Mower (Fits 2024 and Older Models) Robotic Lawn Mower Blade Mounting Disk with 6 Pcs Blades 2Pack Review

Overview

The Upgrade Replacement 6-Blade Disc is a direct-fit blade mounting disk kit designed specifically for the Luba and Luba 2 robotic mowers, covering both 2024 and older models. This 2-pack includes two complete disks with six blades each, totaling 12 blades—perfect for owners who want a spare set ready to swap in when the originals wear down. It’s best for Luba owners who mow medium to large lawns and need a reliable, easy-to-install replacement that maintains the robot’s factory cutting performance without the hassle of sourcing individual parts.

Who Should Buy This

• Luba owners with lawns over 1/2 acre: If you’re running your robot mower daily during peak growing season, blades dull fast. This 2-pack keeps you cutting cleanly without frequent trips to reorder.
• Homeowners who want no-fuss maintenance: You don’t want to measure blade angles or hunt for compatibility—this kit is plug-and-play for Luba and Luba 2, so you can swap in minutes.
• Buyers on a budget who plan ahead: At $39.99 for two complete disks (12 blades total), it’s cheaper per blade than buying OEM singles. Stock up now and avoid last-minute shipping delays.
• Users who mow tough grass or uneven terrain: The six-blade design provides more cutting points per rotation, which helps with dense Bermuda or fescue and reduces the chance of missed patches on bumpy ground.

Key Features Breakdown

• 6-Blade Design per Disk: More blades mean more cuts per pass, which translates to a finer, more even finish—especially important for Luba owners who want that golf-course look without double-mowing. The extra blades also help the robot chew through taller grass without bogging down.
• Compatibility with Luba & Luba 2 (2024 and Older): This is a direct fit—no adapters or modifications needed. The mounting holes and disk diameter match factory specs exactly, so you won’t waste time filing or drilling. It’s verified to work with both the original Luba and the newer Luba 2 models.
• 2-Pack Configuration: You get two complete disks, each with six blades pre-installed. That’s enough for one immediate replacement and one backup. Given that robotic mower blades typically last 2–4 weeks depending on lawn size and debris, this pack covers about two months of heavy use.
• Blade Material: The blades are hardened steel, similar to OEM quality. They resist bending on small rocks and twigs, though they’ll still dull over time—standard for any robotic mower blade.
• Price at $39.99: That’s roughly $3.33 per blade (12 blades total). Compare to OEM blades that often run $5–7 each, and you’re saving 30–50%. The disk itself is reusable, so future replacements only require new blades.

Pros

1. True Plug-and-Play Fit: Installs in under 5 minutes—just remove the old disk, align the new one, and tighten. No shims, no guesswork. Works perfectly on both Luba and Luba 2.
2. Great Value per Blade: At $39.99 for 12 blades, you’re paying less than $3.50 per blade. OEM alternatives can cost double that for the same quantity.
3. Spare Disk Included: Having a second disk means you can swap immediately when blades dull, rather than waiting for a reorder. This is a huge time-saver during peak mowing season.
4. Consistent Cut Quality: The six-blade design produces a clean, even cut across the lawn. Users report fewer stragglers and less clumping compared to the stock four-blade disks on some older Luba models.
5. Durable Construction: The disk itself is rigid plastic that doesn’t warp under sun or moisture. The blades hold their edge reasonably well on typical suburban lawns with occasional sticks or rocks.
6. Low Maintenance: No lubrication, no adjustments—just bolt on and let the robot do its thing. Perfect for owners who want to set it and forget it.

Cons

1. Blades Not Individually Replaceable Easily: While the disk is reusable, the blades are riveted in place. To replace just the blades, you’ll need to drill out the rivets or buy a new disk entirely. This makes the “spare disk” more of a necessity than a luxury.
2. No Extra Screws or Hardware Included: The kit comes with the disks and blades only. If you lose a mounting screw during installation, you’ll need to source one separately—annoying for a product that’s supposed to be a complete replacement.
3. Moderate Long-Term Durability: Some users report the blades dull slightly faster than OEM on sandy or gritty soil. They’re fine for most lawns, but if your yard has heavy clay or frequent debris, expect to swap disks every 3–4 weeks.
4. Limited to Luba Models Only: This won’t work on other robotic mowers like Husqvarna or Worx. If you switch brands down the line, these disks become useless. Make sure you’re committed to the Luba ecosystem.

Bottom Line

The Upgrade Replacement 6-Blade Disc kit is a solid, cost-effective solution for Luba and Luba 2 owners who want to keep their robot mower cutting cleanly without paying OEM premiums. The two-pack design gives you a spare on hand, the six-blade configuration improves cut quality on dense lawns, and the direct fit means zero frustration. The main trade-offs are the non-replaceable individual blades (you’ll need to replace the whole disk when they wear out) and the lack of included hardware. Still, at $39.99 for 12 blades, it’s a smart buy—especially if you mow more than half an acre or want to avoid downtime. I’d recommend this to any Luba owner who values convenience and savings over brand-name loyalty.

Frequently Asked Questions

Q: Will this fit my Luba 2 from 2024?
Yes, this kit is explicitly designed to fit both the original Luba and Luba 2 models, including the 2024 versions. The mounting pattern and disk diameter are identical across all years. Just remove the old disk and bolt this one on.

Q: Can I reuse the disk and just buy replacement blades separately?
Technically yes, but it’s not straightforward. The blades are riveted into the disk, so you’d need to drill out the rivets and install new ones with small screws or new rivets. Most users find it easier to just buy a new disk kit (which is why the 2-pack is handy). Upgrade doesn’t sell blades alone for this disk.

Q: How often should I replace the blades on this disk?
It depends on your lawn size, grass type, and debris. For a typical 1/4-acre lawn mowed daily, expect to swap disks every
