Trimmer Line GEKO G73981 — 2.4 mm x 30 m, pentagonal profile, replacement line for grass trimmers

GEKO G73981 is a 2.4 mm x 30 m replacement trimmer line with a pentagonal profile designed for use in grass trimmers and brushcutters. The five-sided cross-section provides increased edge contact during rotation compared with round lines, which can improve cutting efficiency and produce cleaner edges on turf and weeds. Made of durable nylon material, this shaped trimmer line is intended for general mowing, edging and clearing overgrown patches where a robust, shaped line is required.

Advantages

The pentagonal profile increases the number of cutting edges, improving the ability to slice through stems and dense vegetation while maintaining consistent performance. At 2.4 mm thickness the line balances flexibility and strength for common domestic and light professional tasks. The 30 m length supplies sufficient replacement material for multiple mowing sessions and reduces the frequency of spool refills. The nylon composition offers wear resistance and compatibility with most consumer trimmer heads designed for nylon line.

Suitable for

• General lawn mowing and grass trimming around yards and gardens
• Edging along sidewalks, driveways and flowerbeds
• Clearing light to moderate overgrowth of weeds and tall grass
• Use in trimmer heads that accept 2.4 mm nylon line

Key specifications

• Length: 30 m
• Cross-section: pentagonal (five-sided) profile

How to use

Turn off and, if applicable, disconnect the trimmer from its power source before replacing line. Remove the trimmer head cover according to the tool manufacturer's instructions, wind the pentagonal line onto the spool following the indicated winding direction, and secure the free ends in the retainer slots. Reassemble the head, ensuring the line extends to the recommended length for your trimmer. Start the trimmer at low speed and check line balance and feed operation before regular cutting.

Usage recommendations

Use this 2.4 mm pentagonal line for routine lawn maintenance and edging where improved cutting edges are beneficial. Avoid contact with hard surfaces such as concrete or metal edging to reduce accelerated wear. Check compatibility with your trimmer head and follow the manufacturer's torque and speed recommendations to prevent premature line breakage.
