What it is
The listing behind this page is Oregon’s 2-tooth mulching (shredder) blade: 300 mm across, 4.0 mm thick, with tapered edges, hardened steel at 42–48 HRC and a weight of about 560 g. It meets ISO 7113 and the Machinery Directive 2006/42/EC, and includes a 20 mm aluminium adaptor. It was sold by Amazon when we checked in October 2026. This page’s address refers to a 255 mm 4-tooth blade — the product we link to is this 300 mm 2-tooth one.
2-tooth or 3-tooth?
Two long edges act like a heavy spinning scythe: fast through high grass and lush vegetation, and quick to sharpen. A 3-tooth mulching blade bites better into brambles and woody stems. For lighter machines, Oregon’s thinner 255 mm 2-tooth grass blade is the equivalent.
Will it fit?
A 300 mm blade needs a powerful brush cutter whose manual lists that diameter and the matching guard — larger petrol machines with a bike handle and a full harness. Never fit an oversized blade to a smaller machine.
Safety
Long-edged blades kick back hard if they strike a stump or post in the 12-to-2 o’clock zone — cut with the left side (kickback explained). Fit with the correct washer and nut (how to fit a blade). Compare types in the best brush cutter blades.
