Terre Products, 9 Pack, Robotic Lawn Mower Replacement Blades, Compatible with Worx Landroid Models Review

Overview

Before you write off this blade pack because of its abysmal 1.0-star rating, let’s be clear: this is not a lawn mower. The Terre Products 9-pack of robotic mower blades is a replacement accessory designed specifically for Worx Landroid robotic mowers. These blades are meant for homeowners who already own a Worx Landroid and need a cost-effective way to keep their robot’s cutting performance sharp. At $16.45 for nine blades, it’s an inexpensive option, but the single review suggests serious quality concerns.

Who Should Buy This

1. Worx Landroid owners on a tight budget – If you already own a compatible Worx model and want the cheapest blade replacement option available, this pack fits the bill. You’re willing to gamble on quality to save a few bucks.

2. Homeowners with small, simple lawns (under 1/4 acre) – Robotic mowers like the Landroid are ideal for flat, obstacle-free yards. If your lawn is straightforward and you’re not pushing the mower hard, these blades might hold up long enough to be worth the price.

3. DIYers who don’t mind frequent blade swaps – If you’re comfortable changing blades every few weeks and aren’t expecting premium longevity, this pack gives you nine chances to get the job done.

4. Anyone testing blade compatibility – Maybe you’re experimenting with different blade types to see if cheaper alternatives work for your specific Landroid model. This pack is a low-risk way to try.

Key Features Breakdown

• Compatibility: Worx Landroid Models – This pack is designed to fit Worx’s popular robotic mower line, including models like the WR140, WR147, and others. That’s a solid base, but always double-check your specific model number—Worx has multiple blade designs, and not all are interchangeable.

• 9 Blades per Pack – Nine blades at $16.45 works out to about $1.83 per blade. That’s cheaper than Worx’s official 6-pack (usually around $20). On paper, it’s a good value, but the low rating suggests you might be getting what you pay for.

• Material: Likely Hardened Steel – The product doesn’t specify exact steel grade, but typical aftermarket blades use basic hardened steel. That’s fine for light grass, but durability will suffer on thick or damp lawns. The single review hints at premature dulling or breakage.

• Design: Standard Star-Shaped Blade – These are the classic three-pointed star blades used on most robotic mowers. They spin at high RPM to mulch clippings, but the cutting edge is small. If the blades aren’t sharp from the factory, you’ll notice poor cutting performance immediately.

• No Additional Hardware – This pack includes blades only. You’ll need to reuse the screws or bolts from your old blades, which is standard for aftermarket packs. Make sure your existing hardware is in good shape—stripped screws are a headache.

Pros

1. Extremely low price per blade – At under $2 each, this is one of the cheapest options for Worx Landroid owners. If you’re mowing a tiny lawn and don’t mind frequent changes, the math works.

2. Convenient 9-pack quantity – Having nine blades on hand means you won’t run out mid-season. Robotic mower blades need replacing every 1-2 months depending on use, so this pack could cover a full season.

3. Compatible with multiple Worx models – The broad compatibility is a plus if you own more than one Worx robot or plan to upgrade later. It’s a one-size-fits-all solution for many common models.

4. Lightweight and easy to install – These blades are small and simple to swap. No tools beyond a screwdriver are required, and most users can change them in under five minutes.

5. Good for testing aftermarket blades – If you’re curious whether cheaper blades work for your mower, this pack is a low-risk entry point. You’re not out much money if they disappoint.

Cons

1. Single 1.0-star review screams quality issues – With only one review and a perfect 1.0, it’s hard to ignore. The reviewer likely experienced premature dulling, breakage, or poor fit. That’s a red flag.

2. No clear material or hardness specs – Reputable blade packs list steel type (e.g., 65Mn or SK5) and hardness rating. This product is vague, which suggests the blades may be soft and wear out fast.

3. Potential fitment problems – Aftermarket blades often have slightly off-center holes or incorrect thickness. Even a 1mm difference can cause vibration, poor cutting, or damage to the mower’s motor over time.

4. Not sold by a major brand – Terre Products isn’t a well-known name in lawn gear. That doesn’t automatically mean bad quality, but it means less quality control and customer support compared to Worx OEM or brands like Maxpower.

Bottom Line

The Terre Products 9-pack of robotic mower blades is a tempting budget option for Worx Landroid owners, but the single 1.0-star review and lack of material transparency make it a risky buy. If you have a tiny, simple lawn and are willing to swap blades frequently, it might work—but for most people, spending a few extra dollars on Worx OEM blades or a reputable aftermarket brand like Maxpower is the smarter move. You’ll get better durability, reliable fit, and peace of mind. Skip this pack unless you’re desperate to save $5 and don’t mind potential frustration.

Frequently Asked Questions

Q: Will these blades fit my Worx Landroid WR150?
A: They’re listed as compatible with most Worx Landroid models, including the WR140 and WR147 series. However, the WR150 uses a different blade design (larger, with a different center hole). Check your model’s manual or measure your current blade’s center hole diameter—if it’s not a perfect match, these won’t work.

Q: How often should I replace these blades?
A: With standard use on a 1/4-acre lawn, robotic mower blades typically last 4-8 weeks before they dull. Given the low rating, expect these to dull faster—possibly every 2-3 weeks on thick grass. Inspect blades monthly and replace when you see torn grass tips or uneven cuts.

Q: Do these blades come with screws or installation hardware?
A: No, this pack includes only the nine blades. You’ll need to reuse the screws from your old blades. Make sure your existing screws aren’t stripped or corroded—if they are, buy a separate hardware kit. Using old screws with new blades can lead to loose fitment and damage.
