Trimmer Line GEKO G73978 pentagonal 3.0 mm × 30 m for brushcutters

GEKO G73978 pentagonal trimmer line with a 3.0 mm diameter and 30 m length is designed for use with brushcutters and grass trimmers. The five-sided profile enhances cutting performance by providing sharper contact edges compared with round lines, which helps deliver cleaner cuts on grass and light vegetation. This trimmer line is suitable for routine trimming, edging and clearing of small overgrowth in gardens and yards and is compatible with many consumer and professional handheld cutting heads that accept 3.0 mm lines.

Advantages

The pentagonal cross-section creates multiple cutting edges that improve slicing action and reduce tearing of stems. At 3.0 mm diameter the line balances flexibility and durability, enabling effective trimming without excessive wear on the head. A 30 m spool length provides a practical amount for recurring maintenance tasks and reduces the frequency of replacements. The material formulation resists breakage during normal use while remaining flexible enough to feed reliably from automatic and semi-automatic trimmer heads.

Suitable for

• General lawn trimming and shaping around lawns and flower beds
• Edging pathways and borders where defined cuts are required
• Clearing light overgrowth and weeds in home gardens and small properties

Key specifications

• Profile: pentagonal (five-sided)
• Diameter: 3.0 mm

How to use

Install the trimmer line according to the instructions of your brushcutter or trimmer head. Measure and cut the required length from the spool, then wind the line evenly onto the spool, keeping tension consistent to prevent tangles. Reassemble the cutting head and test-feed the line at low throttle before normal operation. Use appropriate personal protective equipment and follow the tool manufacturer's safety guidelines when trimming.

Usage recommendations

For best results, use this 3.0 mm pentagonal line on medium-duty trimming tasks and edging. Replace the line when cutting performance declines or the diameter is significantly reduced. Store the spool in a cool, dry place away from direct sunlight to preserve material properties.
