CZS 6 Steel Razors Trimmer Head & 3 Teeth Brush Cutter Blade for Weedeater, 65Mn Weed Eater Blades, Weed Eater Head with Adapter Kit for Brush Cutter, Trimmer, Weed Eater

What It Is

This is a 2-in-1 trimmer head system that swaps between a steel razor line head and a 3-tooth brush cutter blade, designed for heavy brush, thick weeds, and saplings up to 1-inch diameter. It’s for gas brush cutters and straight-shaft trimmers, not electric or curved-shaft units.

Fitment & Compatibility

Before buying, measure your trimmer’s shaft diameter and drive system. This kit includes adapter bushings for 25.4mm (1 inch) and 26mm shafts, plus a universal adapter plate with 8mm, 10mm, and 25.4mm center holes. It fits most straight-shaft Weedeater, Echo, Husqvarna, Ryobi, and Craftsman models, but does not fit curved-shaft trimmers or units with a 9-tooth splined drive system (common on some Stihl models). Check your owner’s manual for shaft type and drive system – if you have a 9-spline or 3-spline output, this won’t work without modification. Also verify your trimmer’s cutting head thread is M10 x 1.25 left-hand (standard for most gas trimmers).

Key Things to Know

• Build quality: The steel blades are 65Mn (manganese steel) – tough but can dull fast on rocky soil. The plastic head housing is average; some users report cracking after hitting hard objects.
• Installation: Moderate difficulty. Requires removing the old head, installing the adapter plate, and securing with the included lock nut. You’ll need a wrench and a locking tool (or a screwdriver to hold the shaft). Not a 5-minute job.
• Safety: The brush cutter blade is aggressive – always wear chaps, boots, and eye protection. The blade can throw debris up to 50 feet. Do not use on a trimmer rated under 30cc.
• Conversion time: Switching between line head and blade takes about 2 minutes after initial setup, but the adapter plate stays on the trimmer, which adds weight and may affect balance.

Should You Buy It

Buy this if you have a straight-shaft gas trimmer (30cc+) and need a budget option to clear heavy brush without buying a separate brush cutter. Skip it if you have a curved-shaft or electric trimmer, or if you want a premium, long-lasting head – the 3.7-star rating reflects mixed durability. For occasional heavy use on a standard gas trimmer, it’s a good value at $18.
