Choosing the Right Stihl Mowing Line

Stihl produces a wide range of nylon line types to suit different jobs, head types, and trimmer power levels. Line is colour-coded by profile, helping you choose based on durability, noise level, and cutting strength. All Stihl line is made to resist fraying, welds, and premature snapping under load.

Mowing Line Types by Colour & Profile

  • Yellow (Round): Flexible and low-noise — ideal for general trimming
  • Green (Quiet): Twisted profile — reduced noise and smooth operation
  • Red (Square): More aggressive cut — better on thick grass and coarse weeds
  • Black (DuroCut segments): Tough pre-cut line for DuroCut heads — high durability on heavy ground

Line Diameter Guide

  • 2.0 mm: Light domestic trimmers
  • 2.4 mm: Most mid-range heads (e.g. AutoCut 25-2)
  • 2.7 mm – 3.3 mm: For pro brushcutters and tougher vegetation

Steel Grass Blades Also Available

For jobs where mowing line isn’t enough, Stihl’s GrassCut blades (2, 4 or 8-tooth) offer reliable cutting in dense grass and coarse growth. These are only suitable for machines with blade guards and enough power to handle them.

Used by All Types of Operators

  • Home users replacing line on Stihl strimmers or Kombi tools
  • Gardeners and contractors upgrading to tougher profiles or diameters
  • Tool hire firms restocking line and blade consumables
  • Grounds teams switching to metal blades for seasonal clearance
