KAKO Sawtooth .175 Trimmer Line 298ft Dual-Core Serrated Heavy-Duty String for Walk-Behind & Handheld Trimmers

The KAKO Sawtooth 175 trimmer line is a heavy-duty .175-inch dual-core, serrated nylon string designed to cut thick grass and stubborn weeds faster and last longer than standard round lines.

Built for walk-behind wheeled trimmers and heavy handheld weed eaters, this 298-foot, 3 lb spool combines a sawtooth profile with a reinforced dual-core to deliver higher cutting efficiency, reduced engine drag, and improved durability. It works with major brands and is intended for demanding residential and commercial clearing, edging, and trimming tasks.

How does the sawtooth shape improve cutting performance?

The serrated, sawtooth edges slice through stems and dense vegetation more effectively than smooth round line. Those edges create multiple cutting surfaces so each pass removes more material, reducing the time you spend trimming.

• Sawtooth profile for sharper cutting action
• Multiple edges increase material removal per rotation
• Maintains cutting edge longer than plain round line

Will this .175" line fit my trimmer or walk-behind mower?

The KAKO .175" diameter is compatible with most heavy-duty walk-behind and many handheld trimmers that accept thicker lines. It pairs well with brands like Echo, Husqvarna, Ryobi, Cub Cadet, and Weed Eater, but always check your equipment manual for recommended diameters.

• 0.175 inch diameter fits many commercial and homeowner units
• Works with major brands including Echo and Husqvarna
• Recommended for machines rated for thicker, heavy-duty string

How durable is the dual-core nylon construction?

This line uses high-quality nylon with a reinforced dual-core that resists snapping and excessive wear under heavy loads. The design reduces vibration and engine drag compared with older, brittle lines, giving longer service life per spool.

• Dual-core reinforcement adds tensile strength
• High-grade nylon minimizes breakage and fraying
• Less vibration and lower engine load than traditional lines

What length and weight does the spool provide, and what uses suit it best?

The spool contains 298 feet of .175" line and weighs about 3 pounds, providing ample supply for large yards or professional crews. It's optimized for heavy trimming tasks like thick grass, brush edges, and commercial site cleanup rather than delicate ornamental work.

• 298 feet per spool — long-lasting for large jobs
• 3 lb spool weight for stability and easy loading
• Ideal for heavy-duty trimming, edging, and brush work

Who is this for: KAKO's Sawtooth 175 line is aimed at landscapers, groundskeepers, and homeowners with large or overgrown properties who need a robust, long-lasting trimmer string. If you run commercial equipment or a heavy walk-behind mower and want faster, cleaner cuts with fewer line changes, this product is built for those tougher, time-consuming trimming jobs. For light decorative trimming around delicate plants, consider a thinner, less aggressive line.
