STIHL Square Ø 2.4 mm Mowing Line – 41 / 83 / 253 / 420 m Rolls
The STIHL Square Ø 2.4 mm mowing line delivers aggressive cutting performance for thick, woody grass and stubborn weeds. Its square profile—featuring four sharp edges—cuts cleanly and precisely, much like a brush knife. Choose from roll lengths of 41 m, 83 m, 253 m or 420 m depending on how much work you have and the tools you use.
Aggressive profile for tough vegetation
This square-shaped line gives firm edges that slice through dense growth instead of just rubbing against it. It resists bending or dulling under load, so it continues cutting effectively even in overgrown or neglected areas where round lines struggle to stay sharp.
Durability & roll-length versatility
Made from durable plastic, the Square Ø 2.4 mm line resists wear and maintains cutting quality through heavy use. With long rolls like 253 m or 420 m, you change spools less often; shorter 41 m or 83 m rolls offer more portability and ease of handling for smaller jobs or lighter machines.
Ideal for demanding trimming work
Contractors, professional landscapers and serious gardeners use this line for large-scale trimming, edging fences, clearing overgrown patches and tackling tough weeds. Its square profile supports crisp edges and superior cutting power in tough conditions.
Professional tip for longer life
STIHL recommends soaking the line in water for 12-24 hours before first use. This improves flexibility, lowers the chance of breakage and delivers more consistent performance throughout the life of the line.
