Trimmer Line GEKO G73998-4 square 1.6 mm × 10 m – replacement spool

The GEKO G73998-4 trimmer line is a square-profile replacement line with a 1.6 mm diameter and 10 m length, made for compatible grass trimmers and brushcutters. Its square cross-section increases cutting edge contact and improves cutting efficiency on thicker grass and light weeds. The spool is designed for straightforward winding and fits home garden maintenance tasks and small landscaping jobs that require a durable trimming line.

Advantages

The square geometry of the line provides sharper cutting edges and more consistent performance compared with round line of the same diameter. At 1.6 mm thickness the cord balances flexibility and toughness, reducing breakage when encountering moderate resistance. A 10 m length offers sufficient material for multiple spool refills or for trimming larger areas before replacement. The spool’s construction allows easy winding and installation in trimmers that accept this line size and profile.

Suitable for

• Home garden lawn edging and trimming
• Clearing thicker grass and light weeds
• Small landscaping and grounds maintenance tasks
• Replacement in compatible string trimmers and brushcutters

Key specifications

How to use

Prepare the trimmer according to the manufacturer’s instructions and ensure the unit is turned off and cooled. Remove the spool cover and unwind any remaining line. Cut a length of the GEKO square trimmer line from the spool and wind it evenly onto the spool in the direction indicated by the trimmer housing, keeping moderate tension to avoid tangles. Refit the spool cover securely and trim excess line to the recommended length for your machine. Operate the trimmer following safety guidelines, using steady, controlled passes over vegetation.

Usage recommendations

Use the GEKO 1.6 mm square line for routine garden trimming and edging. Avoid hitting hard surfaces such as concrete or stone to extend line life. Replace the line when wear reduces cutting efficiency or when frequent breakage occurs. Store the spool in a dry place away from direct sunlight to preserve material flexibility.
