STIHL Replacement Blades for PolyCut 6-3, 20-3 & 41-3
These STIHL replacement plastic blades are made to keep your PolyCut 6-3, 20-3 and 41-3 mowing heads performing like new. Supplied in a pack, they provide clean cutting through dense grass and leaves. The blades include a visible STOP mark to show when the blade is worn out and needs replacing, helping you maintain cutting quality and safety.
Clean cutting in tough conditions
The blades deliver a clean cutting pattern even when dealing with thick grass or leaf litter. Their design helps prevent tearing or ragged edges, giving neat results along edges, paths and lawn borders.
Simple tool-free replacement
You can change the blades without any additional tools. The blade’s STOP wear mark makes it easy to tell when it has worn down enough to be replaced. That means less downtime and fewer frustrating stops while maintaining your mowing head.
Broad compatibility
This blade set fits three PolyCut heads: the 6-3, 20-3, and 41-3 models. If you own any of those mowing heads, this pack gives you spares that match perfectly. Having interchangeable blades helps simplify maintenance if you use more than one of these PolyCut heads.
Pro tip for durability
STIHL recommends soaking the plastic blades in water for 12-24 hours before first use. Soaking helps make the plastic more flexible and reduces the chance of breakage during operation. With that simple step, you can extend the lifespan of each blade and keep your mowing results consistent.
