Stihl FSA 86R AUTOCUT 36V AP System Loop Handle String Trimmer – Tool Only
Maintain immaculate turf borders without exhaust fumes, gas mixing, or loud engine noise using the STIHL FSA 86 R 36V AP System Cordless String Trimmer (Tool Only). Purpose-built for professional landscapers, groundskeepers, and property owners working in noise-sensitive zones such as schools, hospitals, HOAs, and municipal parks, it matches commercial gas trimming performance with whisper-quiet battery power.
Driven by a high-efficiency brushless EC motor and STIHL's CONSTANT POWER electronic control, this trimmer keeps line speed steady even as battery charge decreases or when cutting through thick weeds. It features a wide 13.8-inch (350 mm) cutting swath powered by an AutoCut® C 6-2 bump-feed head that reloads line in seconds without opening the housing. The lightweight aluminum straight shaft and adjustable loop handle (R) give you full maneuverability around trees, park benches, and fence lines, while the fold-down wire spacer bracket shields tree bark, vinyl posts, and delicate flower beds from accidental string strikes.
Key Features:
- Commercial 36V Brushless EC Motor: Delivers smooth, instant torque with virtually zero maintenance and ultra-quiet operation.
- CONSTANT POWER Technology: Maintains uniform head speed throughout the battery cycle so performance won't fade.
- AutoCut® C 6-2 Trimmer Head: Easy-loading bump-feed head advances fresh line with a tap and spools line from the outside without disassembly.
- 13.8" Cutting Width (350 mm): Wide cutting swath covers extensive turf areas and lawn borders quickly.
- Fold-Down Wire Spacer Guard: Prevents line impact against tree trunks, flower borders, siding, and painted posts.
- Variable-Speed Trigger: Smooth finger-throttle control allows you to dial in low RPMs for delicate edging or full throttle for heavy grass.
- Ergonomic Loop Handle (R): Soft-grip loop handle provides comfortable, balanced control when trimming on slopes and tight angles.
- IPX4 Splashproof Certified: Tested to operate safely in damp grass and light rain across commercial jobsites.

Frequently Asked Questions
Does this bare tool include a battery and charger?
No. The FSA 86 R is sold as a bare tool (tool only). It runs on any STIHL AP System 36V lithium-ion battery (the AP 200 or AP 300 S is recommended for ideal balance and runtime) and charges on an AL series charger.
How do you reload trimmer line onto the AutoCut® C 6-2 head?
The AutoCut C 6-2 head features STIHL's EasySpool system. You don't have to disassemble the head: simply line up the eyelets, feed the precut trimmer line through, and turn the outer knob by hand to wind the line inside.
Can this trimmer use plastic cutting blades or metal brush blades?
Yes, you can swap the string head for an optional STIHL PolyCut™ 6-2 head using replaceable thermoplastic blades. However, it is not approved for heavy steel brush knives or metal saw blades.
What is the purpose of the fold-down metal wire bracket?
The wire spacer bracket flips down in front of the cutting head to serve as a physical buffer. It keeps the rotating line from stripping bark off fruit trees or scarring fence boards, and flips up out of the way when trimming open grass.
Can the FSA 86 R be used in the rain?
Yes. As part of the STIHL AP professional battery series, the FSA 86 R is certified splashproof to IPX4 standards, making it safe for operation in damp conditions and light rain.
