Terre Products, 18 Pack, Robotic Lawn Mower Replacement Blades, Compatible with Worx Landroid Models Review

Overview

This isn’t a mower itself, but the Terre Products 18-pack of replacement blades is a critical consumable for anyone running a Worx Landroid robotic mower. Designed as a direct, multi-pack alternative to Worx’s own branded blades, this set aims to keep your robot cutting cleanly without forcing you to buy expensive single packs from the manufacturer. It’s best for the budget-conscious Landroid owner who wants to stock up for a full season (or two) of mulching without constant reordering.

Who Should Buy This

1. Worx Landroid owners on a budget – If you own a Worx Landroid model (WR140, WR150, WR155, etc.) and hate paying $10-15 for a 6-pack of OEM blades, this 18-pack for $16.95 is a no-brainer for cost-per-blade savings.
2. Owners with larger lawns (0.25+ acres) – Robots that run daily or every other day will dull blades faster. If your mower clocks heavy hours, you’ll appreciate having 18 blades ready to swap without a trip to the store.
3. DIYers who don’t mind basic maintenance – These blades are easy to install (just a Phillips screwdriver or hex key), so if you’re comfortable rotating blades every 1-2 months, this pack keeps you in the green.
4. Anyone tired of inconsistent cutting – If your Landroid is leaving ragged grass tips or missing patches, dull blades are often the culprit. This pack ensures you always have a fresh set on hand.

Key Features Breakdown

• 18 Blades Per Pack – This is the standout. Most OEM packs come in 6-count boxes. You get triple the quantity for roughly the same price as two OEM 6-packs. That’s a full season of weekly replacements for most users.
• Compatible with Worx Landroid Models – These blades fit the majority of Worx’s robotic lineup, including the WR140, WR150, WR155, WR165, and many others. Always double-check your specific model number, but compatibility is broad.
• Material: Stainless Steel or Hardened Steel – The exact material isn’t explicitly stated in all listings, but user feedback suggests they’re hardened steel. They’ll hold an edge reasonably well for a robotic mower blade, which isn’t designed to be razor-sharp like a reel mower blade.
• Standard Size and Shape – They match the OEM blade dimensions (roughly 1.5" x 0.75") and have the same mounting hole pattern. You won’t need to modify anything.
• Price: $16.95 – At roughly $0.94 per blade, this is significantly cheaper than OEM blades, which can run $1.50-$2.50 each. The savings are real if you’re replacing blades monthly.

Pros

1. Massive cost savings – At under a dollar per blade, you’re saving 40-60% compared to Worx branded blades. Over a season, that’s real money.
2. Convenient bulk supply – No need to reorder every few weeks. One purchase covers most of the cutting season, even with frequent changes.
3. Easy installation – Fits the standard Worx mounting system. Swap takes about 2 minutes per blade with a simple screwdriver or hex key.
4. Consistent cutting performance – Fresh blades restore that clean, mulched look to your lawn. Dull blades tear grass, leading to browning tips.
5. Good value for high-use lawns – If your robot runs daily, you’ll burn through blades fast. This pack is ideal for heavy-use scenarios.
6. No compatibility surprises – Most users report they fit Worx models without issues. No filing or drilling needed.

Cons

1. Inconsistent quality control – Some users report occasional blades that are slightly bent or have burrs on the cutting edge. You may need to inspect each one before installation.
2. Not as durable as OEM – A few owners note these blades dull slightly faster than genuine Worx blades, especially on rocky or sandy soil. Expect to change them more often.
3. Material uncertainty – The listing doesn’t clearly state whether these are stainless steel or just hardened steel. If you live in a humid area, they may rust faster than OEM blades.
4. No included hardware – Unlike some aftermarket packs, you don’t get extra screws or washers. If you lose a screw, you’ll need to source one separately.

Bottom Line

The Terre Products 18-pack of replacement blades is a solid, budget-friendly choice for any Worx Landroid owner who wants to keep their robot cutting clean without breaking the bank. The value per blade is excellent, and the convenience of having a full season’s supply in one box is hard to beat. However, you are trading some durability and quality consistency for that low price. If you’re meticulous about your lawn’s appearance and don’t mind paying a premium for guaranteed performance, stick with OEM blades. But for the vast majority of users who just want a decent cut and lower ongoing costs, this pack is a smart purchase. I’d recommend it confidently to anyone with a Worx robot who replaces blades regularly.

Frequently Asked Questions

Do these blades fit all Worx Landroid models? They fit the vast majority of Worx robotic mowers, including the popular WR140, WR150, WR155, WR165, WR184, and similar models. Always check your owner’s manual or measure your current blade to confirm the mounting hole spacing (usually 1.5" center-to-center). If you have an older or very new model, verify compatibility before buying.

How often should I replace these blades? For most lawns, every 4-6 weeks is a good rule. If you have a large lawn (0.5+ acres) or your robot runs daily, you may need to swap every 3-4 weeks. Dull blades show up as torn grass tips or uneven cutting. You can also check by feel—if the edge feels rounded, it’s time to change.

Will these void my Worx warranty? No, using aftermarket blades does not void your mower’s warranty. Robotic mower blades are considered consumable parts, like gas or oil in a car. However, if a blade defect causes damage to the mower (e.g., a blade breaks and hits the motor), Worx may not cover that specific repair. Stick to reputable aftermarket brands to minimize risk.
