STIHL FS 311

One Machine, Four Attachment Types
The FS 311 accepts mowing heads, grass cutting blades, brush knives, and circular saw blades, so one powerhead handles a wide range of jobs.

230 to 255mm Grass Cutting Blades
Swap to a grass cutting blade for tougher, taller growth that a standard string head can’t keep up with.

200mm Circular Saw Blades
Step up to a 200mm circular saw blade for clearing small saplings and heavier brush.

Proper Deflector for Every Attachment
Each attachment pairs with a matched deflector, keeping the operator protected no matter which tool is mounted.

36.3cc Displacement, 1.9 BHP
A 2.22 cubic-inch, single-cylinder four-stroke engine delivers 1.9 brake horsepower at 8,500 RPM for serious cutting power.

7,360 RPM Max Output Shaft Speed
A max output shaft speed of 7,360 RPM keeps attachments spinning fast enough to power through heavy growth.

24-Ounce Fuel Tank
A 24-ounce fuel tank keeps you working longer between fill-ups.

Simple Mixture Lubrication
Mixture lubrication (50:1 gas-to-oil) keeps maintenance straightforward in the field.

Adjustable Bike Handle
An adjustable bike handle gives two-handed control for stability on heavier attachments like blades and saw blades.

Swings to Transport Position
The handle swings to a transport position for easier carrying and storage between jobs.

Throttle Trigger With Lockout
A throttle trigger with lockout helps prevent accidental engagement for safer operation.

Simple Choke Knob Starting
A straightforward choke knob makes cold starts easy in any season.

Beyond Standard String Trimming
With brush knife and circular saw blade options, the FS 311 tackles saplings and dense brush that standard trimmers can’t touch.

Clear Fence Lines & Ditch Banks
Heavier-duty attachments make quick work of fence lines, ditch banks, and overgrown property edges.

15.9-Pound Powerhead
At 15.9 pounds dry, the FS 311 balances cutting power with a manageable weight for extended use.

One Trimmer, Fewer Tools to Own
Swapping attachments on one machine means fewer separate tools to buy, store, and maintain.

2,800 RPM Idle Speed
A steady 2,800 RPM idle keeps the engine running smoothly between cuts.

Stop Switch for Quick Shutdown
A dedicated stop switch shuts the engine down quickly and reliably at the end of a job.

Consistent Cold-Start Performance
The choke knob delivers consistent starting performance even in cooler conditions.

Built for Confident Operation
Simple, well-placed controls keep the operator focused on the job, not fighting the machine.

Built for Daily Commercial Use
The FS 311 is a professional-grade trimmer engineered for daily commercial use, not just occasional yard work.

Handles Whatever the Job Calls For
From routine trimming to heavier brush clearing, the FS 311’s attachment flexibility keeps it working across seasons.

Built on STIHL’s Professional Standard
Every FS 311 is engineered to STIHL’s professional-grade standard for reliability season after season.

A Real Workhorse, Not Just a Homeowner Trimmer
Don’t let its trimmer roots fool you — with the right attachment, the FS 311 is built for serious commercial and ag work.
