Stihl AutoCut C6-2 mower head 2.0 mm multicoloured — two-strand tap-feed, snap-on replacement

The STIHL AutoCut C6-2 is a 2.0 mm multicoloured replacement mower head that automatically feeds and realigns cutting line by tapping during operation.

Designed for homeowners and professionals who use compatible STIHL trimmers, the AutoCut C6-2 offers a convenient two-strand cutting line system for mowing and light scraping tasks. It fits a range of small STIHL brushcutters and electric trimmers and restores reliable line feed without tools. The head comes assembled and ready to snap onto compatible models, making it a quick service part when worn or when a thicker line is required.

Which STIHL machines work with the AutoCut C6-2?

The AutoCut C6-2 is made to be compatible with several smaller STIHL trimmers and electric models. Before ordering, verify your machine model and shaft type to ensure proper fit and function. It’s commonly used on entry-level petrol and electric brushcutters where a 2 mm line thickness is specified.

• Compatible models: FS 38, FS 40, FS 45, FS 50
• Also fits electric models: FSE 60, FSE 71, FSE 81
• Line diameter: 2.0 mm for general mowing and clearing
• Type designation: C6-2 two-strand head

How does the automatic feed mechanism work during trimming?

The AutoCut C6-2 uses a tap-feed system: light taps of the head on the ground release extra line from the spool while the cutter runs. This means the line is advanced on demand without stopping the engine or stopping work to manually wind line. The mechanism also recenters the cutting strands so they stay balanced and cut evenly.

• Feeding method: tap-to-advance while running
• Automatic re-adjustment after tapping to keep line centered
• Two-line spool reduces vibration compared with single heavy lines
• No tools required to replace the spool in most compatible models

What cutting tasks is the C6-2 best suited for?

With two 2.0 mm cutting lines, this head is intended for regular lawn edge trimming, light mowing of overgrown turf, and clearing thin weeds. It’s not intended as a substitute for heavy-duty brushcutting against thick saplings or dense undergrowth. For heavy material, choose a thicker line or a different head designed for aggressive clearing.

• Ideal for: grass edging, overgrowth maintenance, light clearing
• Not for: cutting thick woody stems or heavy brush
• Line specs: two 2.0 mm strands for balanced, clean cuts
• Operation: works well with standard trimmer guards and attachments

How do I install and maintain the AutoCut C6-2?

Installation is straightforward—remove the old head per your machine’s manual and snap the AutoCut C6-2 into place, following STIHL’s recommended procedure. Routine checks of the spool and replacement of the line when worn will keep performance consistent. Keep the head clean of grass buildup and inspect the housing for damage after heavy use.

• Installation: follow your trimmer’s spare-parts guide for safe mounting
• Maintenance: clean debris, check spool condition, replace line when short
• Storage: store dry to prevent line degradation
• Replacement parts: use genuine STIHL line and spools for best fit

Who this part is for: the STIHL AutoCut C6-2 suits DIY gardeners and trade users who need a quick, dependable head for everyday trimming and light mowing tasks on compatible FS and FSE series machines. Choose this head if you want a 2.0 mm two-strand feed mechanism that simplifies line advancement and reduces downtime while maintaining a balanced cut for lawns, edges, and light vegetation control.
