String line is fine for grass, but the moment the trimmer meets saplings, blackberry canes or a season of neglected brush, line just beats itself to death. The best brush blade for trimmer swaps the spool for steel: a saw-style blade that cuts woody stems instead of slapping them.
Four brush blades made this list: 10 inch steel and carbide options with 3, 40 and 80 teeth, plus a serrated replacement-blade pack for brush cutter heads. Three fit 1 inch or 20 mm arbors on straight shaft trimmers; one fits specific brush cutter heads only. Compare what each listing actually publishes.

Buying guide: best brush blade for trimmer
Tooth count: 3, 40 or 80
Tooth count decides the cut. The ATIE runs 3 steel teeth for hacking through brushwood and dense grass, the FORESTER 40 carbide teeth for faster, smoother cutting, and the AR-PRO 80 carbide teeth for the finest cut here. The Weed Warrior pack uses serrated edges rather than a tooth count. More teeth means a smoother, slower-feeding cut; fewer teeth means aggressive bite in heavy brush. Match the teeth to the stems: saplings want fewer, woody weeds want more.
Carbide vs plain steel
The FORESTER and AR-PRO state carbide teeth, which the FORESTER listing says stay sharper longer. The ATIE is plain steel, 3.0 mm thick, and the Weed Warrior blades are serrated metal. Carbide holds an edge far longer in dirty, gritty brush; steel is cheaper and easier to touch up. Note the AR-PRO title says stainless steel while its bullets say carbon steel; both wordings are in the listing, so the exact alloy is unclear.
Arbor fit: 1 inch or 20 mm
Three blades state their arbor: the ATIE and AR-PRO fit either 1 inch (25.4 mm) or 20 mm arbors, and the FORESTER has a 1 inch arbor hole with a 20 mm bushing included. All three suit straight shaft trimmers; the FORESTER adds that it is not compatible with curved shaft or electric trimmers. The Weed Warrior blades fit only Weed Warrior, Shakespeare and Rino Tuff brush cutter heads, so they are replacements, not upgrades. Check the arbor and the shaft type before ordering.
Conversion kits and guards
A blade needs the right mounting hardware. The FORESTER states a conversion kit is required for setups with a trimmer head and that no kit is needed if the trimmer is already configured as a brush cutter, with the kit sold separately. The FORESTER also pairs blade size to trimmer power: smaller diameters suit 25 to 30cc trimmers and compact guards, while larger blades suit 35cc and up with larger guards. A blade on an underpowered trimmer just bogs down.
Replacement blades vs full blades
The Weed Warrior pack is a different animal: replacement blades for an existing brush cutter head, not a standalone blade. Its listing states it meets ANSI safety standards, the only safety statement in this group, and compatibility with three head brands. If the brush cutter head is already on the trimmer, replacements are the cheap path; if the trimmer still runs line, a full blade plus any needed conversion kit is the upgrade.
Wear eye and hearing protection, long pants and sturdy footwear, and keep bystanders well back while the line or blade spins. Clear stones and debris first, and stop the engine or remove the battery before clearing the head. Refuel only with the engine off and cool. See OSHA landscaping safety. Read our Safety Disclaimer.
Matching It to Your Property
- Overgrown fencelines with saplings: the FORESTER 40T or ATIE 3T for aggressive cutting.
- Woody weeds and brush piles: the AR-PRO 80T 2-pack for smoother cuts, with a spare blade.
- Already running a brush cutter head: the Weed Warrior 3-pack as direct replacements.
- Small trimmer, 25 to 30cc: check the FORESTER size guidance and the arbor fit first.
- Storage: steel blades want a dry shelf; carbide teeth chip if knocked around loose.
The Acre Score explained
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| FORESTER 10in 40T Blade | 9.5 | 32 | 21 | 20 | 0 | 0 |

| Weed Warrior Blades 3-Pack | 9.3 | 23 | 19 | 19 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Each blade is scored on performance, build and value from what its listing states. Performance covers tooth count, stated speed and fit guidance; build covers the blade material and thickness; value covers the pack size and what is in the box. No listing here states a warranty term, so warranty scores nothing across the board. Contradictions inside a listing cost it points.
FAQ: mowing large lots
Can I put a brush blade on any string trimmer?
No. The FORESTER and AR-PRO state straight shaft trimmers only, and the FORESTER excludes curved shaft and electric trimmers. Check the shaft type and the 1 inch or 20 mm arbor before buying, and get the conversion kit if the trimmer still has a line head.
How many teeth do I need?
The picks here run 3, 40 and 80 teeth plus serrated replacements. Fewer teeth bite harder in heavy brush; more teeth cut smoother in woody weeds. The FORESTER notes that more teeth means faster, smoother cutting.
Do carbide blades stay sharp longer?
The FORESTER listing states its 40 carbide teeth stay sharper longer than plain steel. Carbide holds up in gritty brush where steel dulls fast, which is why both carbide picks outscore the steel ones here.
What does a conversion kit do?
It adapts a trimmer set up for a line head to take a blade. The FORESTER states the kit is sold separately and required for trimmer-head setups, while no kit is needed if the trimmer is already configured as a brush cutter.
Are brush blades safe on small trimmers?
The FORESTER pairs smaller blades with 25 to 30cc trimmers and larger blades with 35cc and up, and states a 10,000 RPM maximum. Match the blade diameter to the trimmer’s power and guard size, and wear the protection the trimmer manual calls for.
