Others are brand-specific, such as the Mammotion Cutting Disk for YUKA 1500. Always check your mower’s model number before purchasing.

The Robot Mower Replacement Premium Stainless Steel 24Pcs from RoboUP uses high-strength stainless steel with 52HRC hardness, supporting dual-direction rotation for extended life.
Premium coatings also reduce friction and heat buildup. If you mow wet or dewy grass, coated blades minimize clumping.

Balanced disc construction minimizes vibration, which protects your mower’s motor and reduces noise. The Shophubio Robot Lawn Mower Replacement Disc Blade[/acms_link”>Shophubio disc blade offers a tool-free installation and is balanced for smooth operation across several Husqvarna-style models.
Ease of Installation and Maintenance
Nobody wants a complicated repair job. Most replacement blades come with screws and lock washers. The <a href="Solusoul 50-pack includes pre-coated threadlocker screws to prevent loosening. The Cilivo WA0190 simply requires removing old screws and snapping in new blades.
Cutting discs are typically a bolt-on replacement. The Mammotion Cutting Disk[/acms_link”>does not include blades, so you will need to purchase them separately.

Frequently Asked Questions
How often should I replace robot mower blades?
Most manufacturers recommend replacing blades every 4 to 6 weeks during the mowing season, depending on lawn size and grass type. Dull blades tear grass, leading to a brown, uneven look. For heavy use, consider a bulk pack like the Solusoul 50-pack to always have spares ready.
Can I use any blade on my robot mower?
No, compatibility is critical. Blades must match the disc design and mounting holes. For example, the BHFDKEL 6-Blade Cutterhead only fits Worx Landroid Vision M600. Always check your manual or use our replacement parts category to find model-specific recommendations.
Do I need to replace the cutting disc as well?
Only if the disc is warped, cracked, or worn. Blades wear out faster. Discs can last multiple seasons. The Mammotion Cutting Disk is designed for long life, but if you notice excessive vibration or uneven cuts, it may be time for a new disc.
Are premium stainless steel blades worth the extra cost?
Yes, for longevity and cut quality. Stainless steel blades resist rust and hold an edge longer than standard steel. The RoboUP 24-pack uses 52HRC hardened steel and supports dual-direction rotation, effectively doubling blade life. That means fewer replacements and a healthier lawn in 2026.
