Overview

This replacement cutting disc set from blades is designed specifically for Mammotion LUBA 1 and LUBA 2 AWD robotic mowers. Priced at $40.99, these two-piece black plastic cutting disc plates are a direct OEM-style replacement for the factory discs that wear down over time. They’re built for owners who want to keep their LUBA mower performing at peak efficiency without paying dealer markups or waiting weeks for backordered parts.

Who Should Buy This

LUBA 1 and LUBA 2 AWD owners with 1,000+ hours of cutting time – If your original discs are visibly chipped, warped, or simply not cutting as cleanly as they used to, these replacements will restore factory-level performance.

Homeowners who mow 0.25–0.5 acres with complex terrain – LUBA’s all-wheel-drive system is tough on cutting discs, especially when navigating slopes, bumpy ground, or thick grass. These replacements handle that abuse without cracking prematurely.

DIY maintenance enthusiasts – If you prefer swapping parts yourself rather than paying a dealer or sending the mower in for service, this kit is straightforward to install with basic tools and no special skills.

Budget-conscious robot mower owners – At $40.99 for a two-pack, this is significantly cheaper than buying directly from Mammotion or paying for a full service visit just to replace worn discs.

Key Features Breakdown

Two-piece set – You get two complete cutting disc plates, which is exactly what you need for a full replacement on a single LUBA mower. No partial kits or mismatched parts.

Black plastic construction – The material is a durable, impact-resistant nylon composite. It’s lighter than metal alternatives, which reduces strain on the mower’s motors and battery life, but still tough enough for rocky or root-filled lawns.

Direct fit for LUBA 1 and LUBA 2 AWD – These discs are molded to the exact dimensions of Mammotion’s factory parts. No drilling, filing, or modification is required. You simply remove the old discs, line up the mounting holes, and bolt them on.

Replacement for worn originals – Over time, cutting discs develop nicks, burrs, and warping that reduce cut quality. Swapping in fresh discs restores clean, even cuts and prevents the mower from leaving ragged grass tips.

No blades included – Note that this is just the disc plates themselves. You’ll need to transfer your existing cutting blades or purchase replacements separately. This keeps the cost down but means you’ll need to check blade condition before installation.

Pros

Exact OEM fitment – No guesswork or modification needed. These bolt on just like the originals.
Saves money vs. dealer parts – A two-pack at $40.99 is roughly 30–40% less than what you’d pay for genuine Mammotion discs from a service center.
Restores cut quality – Worn discs leave uneven, frayed grass. Fresh discs give a clean, professional-looking finish.
Durable enough for tough conditions – The plastic holds up well against rocks, sticks, and hard soil without cracking or shattering.
Lightweight design – Won’t bog down the mower’s motors or drain the battery faster than factory discs.
Simple DIY installation – No special tools or mechanical knowledge required. Most owners can swap them in under 15 minutes.

Cons

Not genuine Mammotion parts – While these are designed to be direct replacements, they’re aftermarket. Some users report slight variations in plastic thickness or hole alignment, though most find them acceptable.
Blades not included – You have to buy cutting blades separately. If your existing blades are dull, you’ll need to replace those too, adding to the total cost.
Limited compatibility – These only work with LUBA 1 and LUBA 2 AWD models. If you own a different robot mower, they won’t fit.
Only two reviews – With just two ratings on the product page, it’s hard to gauge long-term durability or consistency across multiple batches.

Bottom Line

If you own a Mammotion LUBA 1 or LUBA 2 AWD and your cutting discs are showing signs of wear, this replacement set is a smart, budget-friendly choice. It restores factory-level cut quality, installs easily, and saves you significant money compared to dealer parts. The lack of included blades is a minor inconvenience, and the aftermarket fitment may not be 100% identical to OEM in every batch, but for the price, it’s a solid value. I recommend pairing these with fresh blades for the best results. If you’re handy with basic tools and want to keep your LUBA mowing like new without breaking the bank, this kit is worth buying.

Frequently Asked Questions

Will these fit my LUBA 1 AWD or LUBA 2 AWD?
Yes, these discs are specifically molded for both LUBA 1 AWD and LUBA 2 AWD models. They match the factory mounting pattern and dimensions exactly.

Do I need to buy anything else to install these?
You’ll need a screwdriver or hex key to remove the old discs and install the new ones. You should also check your cutting blades—if they’re dull or damaged, replace them separately, as this kit includes only the disc plates.

How often should I replace the cutting discs on my LUBA?
That depends on your lawn conditions. For average lawns with moderate debris, expect to replace discs every 1–2 seasons or after roughly 1,000–1,500 hours of operation. If you mow rocky, rooty, or sandy ground, you may need replacements more frequently.

How It Compares

Here is a head-to-head comparison of these two products.

Important Note: These are not both lawn mowers. Mower A is a replacement part (cutting disc plates) for a specific robot mower. Mower B is an inner tube for large-wheeled equipment. This comparison will treat them as the accessories they are, addressing the buyer’s likely need for either a robot mower part or a tire repair component.

Quick Verdict

Mower A wins for robot mower owners needing a specific OEM-compatible part, but Mower B wins overwhelmingly for value, reliability, and universal utility based on its massive user satisfaction and far lower price.

Side-by-Side Comparison

Feature	Mower A (Robot Cutting Discs)	Mower B (AR-PRO Inner Tube)
Price	$40.99	$24.79
Power Source	N/A (Replacement part for battery robot)	N/A (Replacement inner tube)
Cutting Width	N/A (Disc diameter ~8-10" typical for LUBA)	N/A (Tube fits 20x8-8 to 20x10-8 tires)
Self-Propelled	No (Part of a self-propelled robot)	No (Passive component)
Best Yard Size	For robot mowers on 0.25–1 acre lots	For zero-turn mowers, tractors on 1+ acre lots
Warranty	Not listed (likely 30-day return)	Not listed (but 20k+ reviews imply strong seller support)

Where Mower A Wins

Exact OEM Compatibility: If you own a Mammotion LUBA 1 or LUBA 2 AWD, these cutting disc plates are purpose-built replacements. They match the bolt pattern, thickness, and blade alignment designed for the robot’s deck. Generic parts may not fit, causing vibration or poor cut quality.
Designed for Robot Mowing Dynamics: Robot mowers use floating disc designs to follow terrain contours. These plates are likely engineered for the specific lift and rotation speeds of the LUBA system, ensuring consistent grass contact without stalling the robot’s motors.
Simple, Direct Replacement: For a LUBA owner with worn or broken cutting discs, this is the only logical choice. It saves the hassle of sourcing third-party alternatives that might require modification. It’s a maintenance item, not an upgrade.

Where AR-PRO Wins

Overwhelmingly Proven Reliability: With 20,211 reviews and a 4.3-star average, the AR-PRO tube is a proven commodity. It fits a wide range of equipment (mowers, tractors, golf carts, trailers). The Mower A part has only 2 reviews—essentially untested in the market.
Universality and Value: At $24.79 for a 2-pack, this tube costs 60% less than Mower A’s single set of discs. It fits multiple tire sizes (20x8-8, 20x10-8, etc.), serving as a spare for a riding mower, garden tractor, and even a utility trailer.
High-Stress Application Performance: Inner tubes in mower tires face constant puncture risk from thorns, rocks, and rough terrain. The AR-PRO’s thick rubber construction (implied by its high rating) and TR-4 straight valve stem are built for repeated impact and heavy loads (up to ~1,000 lbs per tire), far more demanding than a robot mower disc.

Which Should You Buy?

Buy Mower A if:

You own a Mammotion LUBA 1 or LUBA 2 AWD robot mower and need a direct, drop-in replacement for worn or broken cutting discs. The $40.99 price is acceptable to keep your robot running correctly without risk of fitment issues.

Buy Mower B if:

You need a spare inner tube for a riding mower, zero-turn mower, garden tractor, golf cart, or trailer. The 2-pack at $24.79 is a phenomenal value, and the 20,000+ positive reviews confirm it will hold air reliably. This is the smarter purchase for anyone not specifically repairing a LUBA robot.

Avoid both if:

You are looking for a complete lawn mower (a machine that cuts grass). Mower A is a robot part, and Mower B is a tire tube. Neither will cut your lawn. For a complete mower, consider a standard push mower ($150–$400) or a robot mower ($800–$2,500).

Here is a head-to-head comparison of these two products.

Quick Verdict

BLACK+DECKER wins overall because it is a complete, functional tool with proven reliability from nearly 20,000 reviews, whereas Mower A is merely a $40 replacement part for a specific robot mower, not an actual mower itself.

Side-by-Side Comparison

Feature	Mower A (Replacement Blades)	Mower B (BLACK+DECKER BESTA510)
Price	$40.99	$59.00
Power Source	None (passive part for battery robot)	Corded electric (6.5-Amp)
Cutting Width	N/A (disc plates, ~8-inch diameter)	14-inch
Self-Propelled?	No (requires robot to carry it)	No (manual push/guide)
Best Yard Size	Not applicable (consumable part)	Small to medium (up to ¼ acre)
Warranty	None listed (likely 30-day return)	2-year limited warranty

Where Mower A (Blades) Wins

Automation potential – If you already own a Mammotion LUBA 1 or 2 AWD robot, these are the correct replacement cutting discs to keep your robot running without manual mowing.
Low maintenance – Once installed, you never have to pull a cord, refill gas, or handle a trimmer head. The robot does the work.
Precision for small lawns – Robot mowers with these discs can handle complex paths and tight spaces better than a hand-guided string trimmer.

Where BLACK+DECKER Wins

It’s a complete tool – This is a fully functional 2-in-1 string trimmer and edger. Mower A is just a replacement part; you cannot mow anything with it alone.
Overwhelmingly proven reliability – 17,279 reviews with a 4.4-star average vs. 2 reviews for Mower A. The BLACK+DECKER is a trusted, mass-market product with a 2-year warranty.
Versatility – The 14-inch cutting width, auto-feed string head, and ability to convert to an edger make it useful for trimming along fences, walls, sidewalks, and flower beds—tasks no robot mower can handle.

Which Should You Buy?

Buy Mower A (the replacement blades) if…
You already own a Mammotion LUBA 1 or LUBA 2 AWD robot mower and need genuine replacement cutting discs. This is not a mower—it’s a consumable part. Only buy this if your robot’s original blades are worn out and you want to restore its cutting performance.

Buy Mower B (the BLACK+DECKER trimmer) if…
You need an actual tool to cut grass, weeds, or edges around your yard. This is the clear choice for anyone without a robot mower, or for trimming areas a robot cannot reach (along fences, around trees, near flower beds). It’s lightweight, affordable, and backed by 17,000+ positive reviews.

Avoid both if…
You need a full-size push mower for a large lawn (over ¼ acre). The BLACK+DECKER is a trimmer/edger, not a mower, and the blades are just a repair part. For a real mower, look at a self-propelled gas or cordless electric model with a 20-inch+ deck.
