STIHL Round Ø 4.0 mm Mowing Line – Dark Green
The STIHL Round Ø 4.0 mm Mowing Line is a high-performance, universal line designed for a wide variety of trimming and mowing jobs. With its 4.0 mm diameter (≈ 0.157 in), this wear-resistant elastic material line balances strength and flexibility while delivering reliable cutting power across many STIHL line heads.
Durable material & design
Made from abrasion-resistant and long-lasting elastic material, the line holds up well when in contact with hard surfaces, such as stone or wood. It resists fraying and damage, ensuring fewer breaks and more continuous cutting. The rounded profile makes it slightly less aggressive on obstacles, helping protect both the line and surrounding surfaces.
Specifications & size
This line comes in a thread length of 87.0 m, providing plenty of supply for longer jobs. Its technical details include thread shape “Round”, and thread color “Dark Green”, making it easy to identify among other lines in use. The round shape offers smooth cutting and is easier to spool compared to more complex profiles.
Everyday use & compatibility
You can use this mowing line with many compatible STIHL line heads and even non-STIHL heads, provided they accept 4.0 mm diameter line. It works especially well in areas with heavier grass or thicker growth where smaller diameter line might wear down too quickly. For lighter trimming or intricate edging, smaller diameters might be preferred.
Pro tip for line life
STIHL recommends soaking the new line in water for 12–24 hours before using it. This simple practice helps the line become more flexible, reducing the chance of snapping or fading prematurely and improving durability over its lifespan.
