Compatibility
Compatible with STIHL FS56RCE FS91R FS70R FS94R FS111R FS131 FS91 and related equipment. Before purchasing, make sure your machine’s model number appears in the compatibility list, since blade arbor sizes and bolt patterns can vary between models.
Installation notes
Unscrew the bump-feed head from the gear head and install the blade adapter if not already fitted. Place the blade over the shaft, add the thrust washer, and tighten the lock nut firmly. Spin the blade manually to confirm it turns true before starting the engine. Full protective gear, including a face shield and leg guards, is mandatory when using bladed attachments.
Common questions
Q: Will this 10” x 80T brush cutter blade fit my STIHL FS91R or FS56RCE, or do I need any special adapter?
This blade is listed as compatible with STIHL FS56RCE, FS91R, FS70R, FS94R, FS111R, FS131, and FS91 models. Before installing, verify that your unit is set up to accept a metal brush blade and that the arbor/hardware on your gearbox matches the blade mounting requirements, since some trimmer setups need the correct rider plate, thrust washer, and nut.
Q: Is an 80-tooth 10-inch blade good for thick weeds and brush, or is it mainly for grass?
A 10” 80T blade is typically best for dense grass, heavy weeds, and light brush where you want a cleaner, finer cut than a lower-tooth brush knife. If you’re regularly cutting woody stalks or thicker saplings, make sure your STIHL model has the power and proper guard setup for metal blade use, and avoid forcing the blade through material that’s beyond its intended range.
Q: How should I install and maintain this 10” x 80T blade on my STIHL FS94R or FS131?
Install it with the machine off, spark plug disconnected, and use the correct STIHL blade hardware so the blade is centered and tightened securely in the proper direction. For maintenance, keep the teeth clean, inspect for missing or damaged teeth after each use, and replace the blade if it becomes bent, cracked, or excessively worn rather than continuing to run it.
