Gashwer Brush Cutter Blade Kit for Weedeater with Universal Adapter, 9" x 20T 2-Set Chainsaw Carbon Round Tooth Steel Saw Blades, Compatible with Stihl, Husqvarna, Ego, Oregon, Hitachi Trimmer

What It Is

This is a 9-inch, 20-tooth round-tooth saw blade kit designed to convert a string trimmer into a brush cutter. It includes two carbon steel blades and a universal adapter, intended for clearing thick weeds, saplings, and overgrown brush.

Fitment & Compatibility

• Check the arbor size: The universal adapter fits most common shaft sizes (typically 1-inch or 20mm), but verify your trimmer’s shaft diameter and drive hole shape before buying.
• Power rating: This blade is for gas trimmers with at least 25cc engines or electric models with equivalent torque. Underpowered trimmers may stall or damage the gearbox.
• Brand compatibility: Works with Stihl, Husqvarna, Ego, Oregon, and Hitachi trimmers, but not all models. Confirm your trimmer has a straight shaft (curved shafts often lack the needed torque).
• Safety shield: You need a dedicated brush cutter shield (not a standard trimmer guard) to use this blade safely. Not included.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the string head, attach the adapter, and torque the blade nut to spec (typically 20-30 ft-lbs). Over-tightening can strip threads.
• Universal adapter may wobble: Some users report slight vibration if the adapter doesn’t fit perfectly. Tighten carefully and test at low speed first.
• Carbon steel dulls quickly on rocky soil: The round tooth design cuts well in grass and light brush, but hitting rocks or gravel will blunt the teeth fast. Resharpening with a file is possible but tedious.
• Not for heavy-duty clearing: This is a light brush blade. For dense saplings over 1-inch diameter, consider a heavier carbide-tipped blade.

Should You Buy It

Buy this if you need a budget-friendly way to clear thick weeds and small brush with your existing gas or high-torque electric trimmer, and you’re comfortable with basic installation. Skip it if you have a low-power trimmer, need a heavy-duty blade for stumps or rocky terrain, or prefer a no-hassle string head.
