Is the Stihl MS 311 a Pro Saw? No – It’s a Farm and Ranch Saw

If you searched “is the Stihl MS 311 a pro saw,” you’re probably standing in a dealer’s showroom or already own one and want a straight answer. Here it is: Stihl itself does not list the MS 311 as a professional saw. On Stihl’s own site, the MS 311 is cataloged under the Farm and Ranch lineup, a tier below the true Professional Series that includes saws like the MS 261, MS 362, and MS 462. That doesn’t make it a bad saw or even a weak one – it’s a capable 59 cc chainsaw built for property owners who cut a lot of firewood, clear brush, or manage a few wooded acres. It just isn’t the saw Stihl builds for someone running a chain eight hours a day, five days a week. Below is exactly how Stihl classifies the MS 311, what actually separates a “Professional” Stihl saw from a Farm and Ranch model, and who the MS 311 is genuinely built for.

The Short Answer: Stihl Puts the MS 311 in Its Farm and Ranch Lineup

Go to Stihl’s own website and look up the MS 311, and you’ll find it filed under chain-saws/farm-and-ranch-saws, not under the Professional Series. That’s not a marketing quirk – Stihl uses this split deliberately across its whole lineup. Farm and Ranch saws (the MS 251, 271, 291, 311, and 391, among others) are engineered for landowners doing regular but not continuous cutting: firewood processing, storm cleanup, fence-line clearing, and felling the occasional tree on a few acres. The Professional Series (MS 261, 362, 400, 462, 500i, and the rest) is built and warrantied for full-time commercial use by loggers, arborists, and tree services.

What Actually Separates a “Professional” Stihl Saw From a Farm and Ranch Saw

The Professional/Farm-and-Ranch split isn’t just a label Stihl slaps on for pricing. A few real differences show up across the lineup:

• Duty-cycle engineering: Professional-series engines and clutches are built and tested for continuous, all-day operation. Farm and Ranch saws are designed around intermittent use – a few hours at a stretch, not eight-hour shifts, day after day.
• Handle configuration: Most true Professional saws (MS 261 and up) offer a full-wrap handle option for felling and bucking from awkward angles, standard equipment for arborists working in a tree. Farm and Ranch saws like the MS 311 only come with the standard rear handle.
• Materials: Higher-end Professional models use magnesium housings and components in places Farm and Ranch saws use reinforced plastic – lighter and more heat-resistant for saws that run hot, all day, every day.
• Parts and dealer support: Professional saws are backed by Stihl’s commercial parts and service pipeline through pro dealers, prioritized for fast turnaround when a saw goes down mid-job. Farm and Ranch saws get full dealer support too, just not the same commercial-priority track.

None of this means the MS 311 is underbuilt. It means Stihl engineered it for a different duty cycle than the saws it sells to commercial crews.

Stihl MS 311 Specs at a Glance

Spec	Stihl MS 311
Engine displacement	59.0 cc
Power output	2.8 kW (3.8 hp)
Powerhead weight	14.1 lbs
Bar length options	16″, 18″, or 20″
Stihl series	Farm and Ranch

A 59 cc engine putting out 3.8 hp is genuinely strong for a homeowner-class saw – it’ll drop a 20-inch hardwood without complaint. But compare that to a true Professional saw like the MS 362 (59.0 cc as well, but tuned and rated for continuous commercial duty) and the difference isn’t raw displacement, it’s what the engine and drivetrain are built to sustain hour after hour.

Where the “MS” Name Actually Comes From (It’s Not What You Think)

You’ll see it claimed online that “MS” stands for “Magnum Series.” It doesn’t. Stihl is a German company, and “MS” is short for Motorsäge – literally “motor saw,” the German word for chainsaw. Every Stihl chainsaw model, from the homeowner-grade MS 170 up through the professional MS 500i, carries the MS prefix for that reason; it’s not a tier or quality indicator by itself. The number after it (261, 311, 362, 462) identifies the specific model, and that’s where the real Professional vs. Farm-and-Ranch distinction actually lives – not in the letters.

Who the MS 311 Is Actually Built For

The MS 311 is aimed squarely at rural property owners, hobby-farm operators, and serious DIYers – people who need real cutting power on a regular basis but aren’t running a saw as their full-time job. Typical work it handles well:

• Processing several cords of firewood a season
• Felling and bucking small to medium trees on a few acres
• Storm and windfall cleanup
• Fence-line and brush clearing on a farm or ranch

Where it’s genuinely the wrong tool is full-time commercial tree work – a tree service running a saw all day, every day, or an arborist doing technical climbing cuts that call for a full-wrap handle. That’s what Stihl’s Professional Series exists for, and it’s priced and warrantied accordingly.

How the MS 311 Stacks Up Against Stihl’s True Professional Saws

For context, here’s where the MS 311 sits next to two saws Stihl does classify as Professional:

Model	Series	Displacement	Full-Wrap Handle Option
MS 311	Farm and Ranch	59.0 cc	No
MS 261	Professional	50.2 cc	Yes
MS 362	Professional	59.0 cc	Yes

Notice the MS 362 matches the MS 311’s displacement almost exactly. The gap between them isn’t engine size – it’s the duty-cycle rating, handle options, and commercial parts/service tier that come with Stihl’s Professional badge. If your work genuinely calls for a saw in that Professional tier, our breakdown of the Stihl MS 391 – another Farm and Ranch model often confused for a pro saw – covers the same distinction from a different angle.

Frequently Asked Questions About the Stihl MS 311

Is the Stihl MS 311 a pro saw?

No. Stihl classifies the MS 311 under its Farm and Ranch lineup, not its Professional Series. It’s a capable 59 cc homeowner and farm/ranch saw, but it isn’t rated or warrantied for full-time commercial use the way Stihl’s true Professional saws (MS 261, 362, 462, and up) are.

Is the Stihl MS 311 a good chainsaw?

Yes, for its intended job. It’s a reliable, powerful 59 cc saw well suited to firewood processing, brush clearing, and cutting small to medium trees on a few acres of land. It’s simply built for regular property-owner use, not continuous commercial duty.

What does “MS” mean in Stihl saws?

“MS” is short for the German word Motorsäge, meaning “motor saw” or chainsaw. It appears on every Stihl chainsaw model regardless of tier – it does not stand for “Magnum Series,” and it isn’t itself a quality or professional-grade indicator.

What size bar can you put on a Stihl MS 311?

The MS 311 is available with a 16″, 18″, or 20″ bar from the factory, and 20″ is the maximum bar length Stihl specifies for this saw.

Conclusion

The Stihl MS 311 is a strong, dependable 59 cc chainsaw – just not a “pro saw” by Stihl’s own definition. It’s cataloged under the Farm and Ranch line, built for landowners handling regular firewood, brush, and small-tree work rather than commercial crews running a saw all day. If that’s your use case, the MS 311 is more than enough saw. If you genuinely need Professional-series durability, handle options, and commercial parts support, look at the MS 261, MS 362, or MS 462 instead.
