Terre Products, 18 Pack, Robotic Lawn Mower Replacement Blades, Compatible with Husqvarna Automower, Gardena Sileno, McCulloch ROB S Series, and More

What It Is

This is an 18-pack of replacement blades for robotic lawn mowers, designed for use with Husqvarna Automower, Gardena Sileno, McCulloch ROB S Series, and similar models. It’s a consumable part that needs periodic replacement to maintain cutting performance.

Fitment & Compatibility

• Brand fit: Compatible with Husqvarna Automower (305, 310, 315, 420, 430X, 440, 450X, 520, 550), Gardena Sileno (city, life, life+), McCulloch ROB S (S600, S800, S1000), and other models using the same blade pattern.
• Check blade dimensions: OEM Husqvarna blades are typically 3.0” long x 0.5” wide x 0.04” thick. Measure your existing blade to confirm these match.
• Mount hole: Verify the center hole diameter (usually 0.25”) and overall shape—some aftermarket blades have slightly different holes that may not seat properly.
• Deck compatibility: Works with standard robotic mower decks (no specific deck size limit), but not for push or ride-on mowers.
• OEM vs aftermarket: These are third-party blades, not genuine Husqvarna. Fitment may vary depending on manufacturing tolerances.

Key Things to Know

• Quality concerns: Only 2 reviews with a 1.6/5 rating—reports of poor sharpness, uneven edges, and blades breaking prematurely.
• Installation: Simple swap—remove old blades, align new ones on the cutting disc, and secure with screws. No special tools needed.
• Common gotchas: Blades may be thinner or softer than OEM, leading to faster wear. Also, some users report the blades don’t stay tight and come loose during operation.
• Pack value: 18 blades at $17.45 is cheap per blade, but if they fail quickly, total cost may exceed OEM replacements.

Should You Buy It

Only if you’re on a tight budget and willing to risk poor performance or early failure. Given the low rating and quality complaints, you’re better off spending a few dollars more on OEM or well-reviewed aftermarket blades from brands like Oregon or Rotary. Skip this if you want reliable, long-lasting cuts.
