Trimmer Line GEKO G73964-4 reinforced square 1.3 mm × 15 m for brushcutters

Reinforced square trimmer line GEKO G73964-4 with a 1.3 mm diameter and 15 m length is designed for use with a wide range of brushcutters and grass trimmers. The square cross-section delivers a sharper cutting edge than round lines, improving cutting efficiency on grass, weeds and light woody stems. Reinforced construction increases wear resistance for prolonged use in demanding conditions while maintaining compatibility with standard line-fed heads that accept 1.3 mm line.

Advantages

The reinforced material and square profile provide improved cutting performance and longer life compared with standard round lines of similar diameter. The 1.3 mm thickness balances flexibility and strength, allowing reliable feed through many automatic and semi-automatic trimmer heads. A 15 m spool length offers enough line for multiple jobs and reduces the need for frequent replacements during routine lawn maintenance.

Suitable for

• General lawn mowing and trimming around lawns
• Edge trimming along paths and flowerbeds
• Clearing dense grass, weeds and light brush
• Use with brushcutters and trimmers that accept 1.3 mm line

Key specifications

• Cross-section: square profile for improved cutting edge
• Line diameter: 1.3 mm
• Length: 15 m
• Construction: reinforced for increased wear resistance
• Compatibility: suitable for trimmer heads designed for 1.3 mm line

How to use

Unload the required length of line from the spool and follow the trimmer head manufacturer’s instructions for winding and securing the line. Ensure the trimmer is switched off and the spark plug or battery is disconnected before replacing or loading line. After loading, test the feed mechanism at low speed to verify smooth operation and proper seating of the line in the head before normal cutting.

Usage recommendations

For best results, use the reinforced square line for regular maintenance and tougher vegetation where improved cutting performance is needed. Replace the line when wear reduces cutting efficiency or if noticeable fraying occurs. Avoid striking hard surfaces such as rocks, concrete or metal objects to extend line life and prevent accelerated damage.
