STIHL AutoCut 46-2
The STIHL AutoCut 46-2 is a lightweight and robust mowing head designed for efficient mowing and clearing. Built with a double mowing line system, it is ideal for trimming grass and thinning vegetation, giving you dependable performance even in more demanding conditions. With its low-profile design, it offers better control and precision, making it easier to achieve neat results around edges and across wider spaces.
Strong and efficient cutting
The AutoCut 46-2 uses a double line that automatically extends when you tap the head on the ground. This system keeps the line at the right working length, reducing interruptions and helping you maintain an even workflow. It’s especially useful for extended trimming sessions where consistency is key.
Durability and protection
For longer service life, the mowing head can be combined with a spool that includes metal protection. This extra reinforcement helps guard against wear, ensuring the AutoCut 46-2 continues to perform well over time. Its sturdy build and practical design make it a reliable choice for regular use.
Line compatibility
This mowing head is compatible with 2.7 mm, 3.0 mm and 3.3 mm mowing line. With these options, you can adapt to different vegetation densities, from lighter grass to tougher growth, without needing to change equipment.
Machine compatibility
The AutoCut 46-2 fits several STIHL machines, including the FS 361 C-EM, FS 411 C-EM, FS 461 C-EM / L, FS 491 C-EM, and the FSA 400. This makes it a versatile mowing head across a range of brushcutters and clearing saws, offering strong performance on both petrol and battery-powered models.
Professional tip for longer line life
STIHL recommends soaking new mowing line in water for 12–24 hours before first use. This makes the line more flexible and less likely to break, extending its lifespan and improving reliability during cutting.
