STIHL Square Ø 3.0 mm Mowing Line – 53 m, 162 m & 271 m Rolls
The STIHL Square Ø 3.0 mm mowing line delivers aggressive cutting power for thick, woody grass and stubborn weeds. Its square profile, with four sharp edges, cuts precisely like a brush knife. STIHL offers this line in three roll lengths—53 m, 162 m and 271 m—so you can choose the size that matches your trimming needs.
Aggressive profile for tough conditions
This line’s square profile gives firm edges that slice through dense vegetation. Unlike round lines, it resists bending and dulling under load. You get strong performance in overgrown areas, around fences, and places where weeds and coarse grass are problems.
Durability & versatile lengths
Made from durable plastic, the Square Ø 3.0 mm line stands up well to wear. Thanks to its material and shape, it resists fraying and maintains cutting quality even after heavy use. The choice of 53 m, 162 m or 271 m rolls means fewer spool changes for frequent users and more flexibility for smaller jobs.
Practical use cases
Professional landscapers and homeowners use this line where powerful trimming is needed: clearing thick weeds, edging large lawns, or trimming in neglected areas. The square shape ensures neat cutting results and strong resistance to wear in tough conditions.
Professional tip for longer line life
STIHL recommends soaking the line in water for 12–24 hours before first use. Soaking improves flexibility, lowers the risk of breakage, and helps maintain performance across the full length of the roll.
