Overview

The STIHL Mowing Head SuperCut 20-2 is a fully automatic, two-line cutting head engineered for professional landscapers and demanding homeowners using STIHL petrol and battery-powered trimmers. Designed to maximize operational efficiency, the SuperCut 20-2 automatically maintains the nylon line at the optimal cutting length during use, eliminating the need to manually tap the head on the ground or stop to pull out line.

Equipped to hold 2.4 mm (0.095″) nylon trimmer line, the SuperCut 20-2 continuously feeds line via centrifugal acceleration as the nylon wears down against obstacles. This makes it ideal for rapid edge trimming, mowing large grassy areas, and working around fence lines, trees, and stone walls. Compatible with a wide variety of STIHL straight-shaft and backpack trimmers (such as the FS 55, FS 56, FS 70, FS 91, FS 131, and FSA 135), it delivers continuous, high-performance cutting action with minimal downtime.
