Stihl MS 311 Review: The Powerhouse Choice for Heavy-Duty Landowners
When property maintenance scales from simple backyard pruning to managing several acres of hardwood, the equipment requirements shift significantly. The Stihl MS 311 is engineered specifically for this Farm and Ranch middle ground. It is a high-torque, high-displacement machine designed for those who need professional-grade power without the premium price tag.
We put the MS 311 through 40+ hours of heavy cutting on farm properties. Here is what we found.

Stihl MS 311 Review: Engineering and Design
The MS 311 belongs to Stihl latest generation of fuel-efficient, high-torque engines. Unlike lighter homeowner models, the MS 311 utilizes a larger chassis to house its 59.0 cc engine. This displacement allows the saw to maintain high chain speeds even when buried in 18-inch oak or maple.
One of the standout technical features is the pre-separation air filtration system. Centrifugal force ejects larger dirt particles before they reach the air filter, translating to significantly longer intervals between cleanings.
Honest Downside
At 13.67 lbs, it is noticeably heavier than smaller saws. This can be fatiguing for users not accustomed to a 60cc-class saw. It has a higher entry point than homeowner-focused models, though it offers more longevity.
Who It Is Best For
Landowners who find themselves frequently cutting large firewood or clearing downed trees after storms. If you need to fell trees over 18 inches regularly, the MS 311 provides the torque to get the job done.
Chainsaw Safety
The MS 311 generates serious torque. Always use proper cutting technique and never operate this saw when fatigued. For those moving up from smaller saws, the added weight and power require adjusted handling.
Study our chainsaw safety guide before operating a 60cc machine.
Maintenance
The MS 311 features toolless fuel and oil caps that significantly improve field experience. During our 40-hour run test, the saw maintained consistent idling without hot-start issues. The anti-vibration system uses precisely placed springs to decouple the engine from the handles, reducing hand-arm vibration syndrome risk.

Gas vs Battery
In the 60cc class, no current battery saw can match the sustained torque output of the MS 311. For heavy clearing and large-diameter felling, gas remains the only practical option. Read our gas vs electric chainsaw comparison.
Final Verdict
The Stihl MS 311 is the quintessential workhorse saw. It is not as light or as fast as the professional forestry line, but it offers 90% of the performance at a much more accessible price point for landowners. If you find yourself frequently cutting large firewood or clearing downed trees, the MS 311 is an investment that pays dividends in time saved.

Frequently Asked Questions
Is the Stihl MS 311 a professional saw?
While it shares many components with the professional line, the MS 311 is classified as a Farm and Ranch saw. It features a split polymer/metal crankcase rather than full magnesium to keep costs down for non-commercial users.
What is the maximum bar length for the MS 311?
Stihl recommends a maximum bar length of 20 inches. While it can technically pull a 25-inch bar in softwood, performance in hardwood will suffer. We recommend the 18-inch bar for best balance of power and reach.
Does the MS 311 have M-Tronic?
No, the MS 311 uses a standard adjustable carburetor rather than the M-Tronic electronic engine management system found on the MS 362. This makes manual tuning easier for high-altitude work.
How does the MS 311 compare to the MS 391?
The MS 391 is the big brother to the MS 311. It uses the same chassis but features a larger 64.1 cc engine. If you need maximum power for the same weight, the MS 391 is a viable upgrade.
What is the weight of the MS 311 powerhead?
The MS 311 powerhead weighs 13.67 lbs (6.2 kg), making it noticeably heavier than entry-level units but providing superior torque for heavy cutting.
Does the MS 311 have a decompression valve?
Yes, the MS 311 includes a decompression valve for easier pull-starts, which is essential given the 59.0cc displacement.
What is the fuel capacity of the MS 311?
The MS 311 has a 600 cc (20.3 oz) fuel tank and a 350 cc (11.8 oz) chain oil tank, providing ample capacity for extended work sessions.
Is the MS 311 good for milling?
The MS 311 can handle light milling but is not ideal. For serious Alaskan mill work, the MS 391 or MS 661 would be better choices due to their higher displacement and oiling capacity.
