Trimmer Line GEKO G73997 karbowana (serrated) 2.4 mm × 100 m for grass trimmers

Replacement trimmer line GEKO G73997 with a serrated (karbowana) profile, 2.4 mm diameter and 100 m length. This trimmer line is designed for use in grass trimmers and brushcutters that accept round or serrated nylon line. The serrated edge increases cutting efficiency on thin stems and tougher weeds while maintaining a stable diameter for reliable feeding from compatible spools and cutting heads. Intended for domestic and light professional garden maintenance, it is suitable for edging, trimming around obstacles and clearing overgrown patches of vegetation.

Advantages

The serrated profile improves cutting performance compared with smooth round line on fibrous weeds and grassy growth. A consistent 2.4 mm diameter balances flexibility and durability, reducing breakage during normal trimming tasks. The 100 m length provides extended runtime between spool refills and can be cut to fit a variety of spool sizes. Made from resilient nylon material, the line resists wear from contact with stones and hard surfaces while remaining compatible with common trimmer heads and refill systems.

Suitable for

• Lawn edge trimming and finishing work
• Clearing weeds, light brush and overgrowth
• Home garden maintenance and seasonal tidying
• Refilling compatible trimmer spools and universal bump heads

How to use

Measure and cut the required length of trimmer line to fit your trimmer spool or bump head according to the manufacturer's instructions. Wind the line evenly onto the spool, maintaining tension and leaving the recommended end lengths for proper feed. Install the spool or head onto the trimmer and test feed operation at low engine or motor speed before full use. Replace worn or damaged sections of line promptly to maintain cutting performance and avoid overloading the trimmer motor.

Usage recommendations

For best results, use the serrated 2.4 mm line on grass and fibrous weeds; avoid prolonged contact with hard surfaces such as concrete or stone to reduce wear. Follow your trimmer manufacturer's guidance on maximum line diameter and spool capacity to ensure compatibility and safe operation.
