The Green Piece replacement blade kit is engineered specifically for Anthbot robotic lawn mowers, offering a precise fit with a slightly larger hole that simplifies installation. This 30-piece set includes matching screws, so you have everything needed for multiple blade rotations over the season.
The blades are made from high-quality stainless steel with a titanium coating, providing excellent edge retention and resistance to rust and corrosion.

Buying Guide: What to Look for in Robot Mower Blades for St Augustine Grass
St Augustine grass has a tough, fibrous texture that can challenge standard blades. Choosing the right replacement set means understanding a few key factors. Here’s what we consider most important.
Blade Material and Coating
Stainless steel is the baseline for rust resistance, but a titanium coating takes durability further. Titanium‑coated blades, like those from FOTEEMO and Antanker, stay sharper longer against abrasive grass fibers. High‑hardness steel (52 HRC or above) also reduces the need for frequent changes. For deeper insights, read our comparison of OEM vs aftermarket blades.
Compatibility with Your Mower Model
Not all blades fit every robot mower. St Augustine lawns often require specific mounting holes and screw sizes. Sets like Green Piece® Robot Mower Blades for Anthbot are precision‑matched to that brand, while universal packs (e.g., M METERXITY) work across many models. Always verify compatibility before ordering.
Cutting Performance and Double‑Sided Design
Double‑sided blades allow you to flip them for extended life, a huge advantage for St Augustine grass, which can wear down one edge quickly. Multi‑direction blades, like those from RoboUP, wear evenly on both sides. Look for packs that include multiple blades and screws so you can rotate fresh edges throughout the season. For additional tips on handling tough turf, check this guide for tough grass.
Value and Quantity
St Augustine grass may require blade changes every 4 to 6 weeks during peak growth. Kits with 30 or 36 blades (like Green Piece or M METERXITY) provide year‑round supply without repeat purchases. A good balance of cost and volume keeps your mower running at peak efficiency without breaking the bank.
Final Thoughts
For St Augustine grass, we recommend starting with Green Piece® Robot Mower Blades for Anthbot if you own an Anthbot mower, their 30‑piece kit and double‑sided design are ideal for fibrous turf. If you need a universal option with titanium coating, the FOTEEMO Robotic Lawn Mower Blades Compatible pack offers outstanding edge retention across multiple brands, including Worx Landroid and Einhell. Both options deliver the clean, even cut that St Augustine grass demands, keeping your lawn lush all season long.
