Yutacorex 9" x 20T Brush Cutter Blade for 1" Arbor — Heat‑Treated Carbon Steel with 2 Adapter Kits

The Yutacorex 9" x 20T chainsaw-tooth brush cutter blade is a durable carbon-steel replacement blade with two adapter kits that lets compatible STIHL, Husqvarna and other trimmer gear heads cut dense brush, saplings and thick weeds quickly and consistently.

This replacement blade package includes two sets of adapter hardware sized for common gear heads and a 1" arbor blade built from heat- and rust-resistant carbon steel. Engineered to work with many popular string-trimmer and brushcutter models, the 20-tooth saw-style blade delivers faster, tooth-by-tooth material removal than a standard nylon line and prolongs service life when used for heavy vegetation and small-diameter woody growth.

Which trimmers and gear heads will this blade fit?

The blade is made for 1-inch arbor mower heads and lists compatibility with many STIHL and Husqvarna gear heads plus several other brands. Before buying, match the adapter and gear-head part number or your trimmer model to one of the supplied adapter configurations to ensure correct fitment.

• Fits STIHL models such as FS56RCE, FS91R, FS70R, FS94R, FS111R, FS131 and related gear head part numbers.
• Compatible with Husqvarna gear heads and models like 128LD, 525L, 130L and others that use a 1" arbor.
• Works with various third-party mowers and brands using the same arbor and gear-head mounting interface.

How durable is the 9" carbon-steel 20-tooth blade?

The blade is constructed from carbon steel that has been treated for heat and corrosion resistance to extend cutting life under regular use. Its saw-style teeth are designed to resist wear while slicing through woody stems and thick grass, so it performs reliably where nylon line slows down.

• 9" diameter with 20 cutting teeth for aggressive material removal.
• Heat-treated carbon steel for improved toughness and rust resistance.
• Designed for longer service life than typical plastic line on heavy vegetation jobs.

What adapters and hardware are included, and how easy is installation?

This set provides two adapter kits that cover different gear-head designs: one kit includes parts for a 10-tooth compatible configuration and the other for 6-tooth gear heads. Each kit contains the thrust washers, rider plate, guard washer, collar nut and the small tools you need to swap the blade, making installation straightforward for anyone comfortable with basic outdoor tool maintenance.

• Two distinct adapter kits: one for STIHL-type 10-tooth interfaces and one for Husqvarna/Jonsered 6-tooth variants.
• Includes collar nuts, thrust washers, rider plates and an L-wrench or screwdriver for mounting.
• Clear note to verify model or gear-head part number before installation to prevent mismatch.

When should I choose this blade over nylon line or a multi-purpose metal blade?

Choose the 20-tooth saw blade when you need faster cutting of medium woody growth, dense weeds or small saplings that quickly wear or tangle nylon line. It delivers cleaner, quicker cuts while the adapter kits let you mount it on many popular trimmer gear heads without modifying your equipment.

• Best for heavy brush, thick weeds and small-diameter woody stems.
• Not intended for cutting large trees or metal; use appropriate safety equipment and guards.
• Ideal when you need durable, repeatable cutting performance on challenging growth.

Who is this for: Landscapers, property owners and maintenance crews who need a robust replacement blade for string trimmers and brushcutters that accept a 1" arbor. If your work regularly involves cutting through tough brush, saplings and dense vegetation and your trimmer model matches one of the supported gear-head configurations, this Yutacorex blade plus dual adapter kit simplifies upgrades and extends cutting capability. Always check compatibility with your trimmer model or gear-head part number and follow safety procedures—wear leg protection and eye protection when operating brush blades.
