Stihl MS 201 TC-M Review: The Scalpel of the Professional Arborist

If you have spent any significant time hanging from a harness sixty feet up a spread oak, you know that your saw is not just a tool—it is an extension of your forearm. For years, the industry lived in the shadow of the legendary Stihl MS 200T. When that saw was discontinued, we all panicked. The initial replacement, the first-generation 201T, felt like a step backward.

Then came the Stihl MS 201 TC-M.

The M stands for M-Tronic, and that single letter changed the game. We have put over 400 hours on our primary 201 TC-M over two seasons. This is not a homeowner weekend toy. If you are looking to cut firewood in your driveway, go buy a Stihl MS 170 and save your money. But if your paycheck depends on how fast you can dismantle a canopy without your shoulders giving out, stay tuned.

Stihl MS 201 TC-M Review: The M-Tronic Brain

The heart of this saw is not just the piston—it is the microprocessor. The M-Tronic system is an electronic engine management system that adjusts ignition timing and fuel metering in all operating modes. It accounts for temperature, altitude, and fuel quality.

The Death of the Adjustment Screw

You will notice the absence of L and H screws on the carburetor. Old-school grease monkeys find this terrifying. But the M-Tronic 3.0 system handles the fuel-air mixture so precisely that it eliminates manual tuning. During our field notes from last February, the saw started on the second pull in 15-degree weather and maintained a perfect idle without that cold-blooded stall we used to suffer through with the 200T.

2-MIX Engine Architecture

Stihl 2-MIX engine uses a stratified charge system. A layer of fuel-free air sits between the burned charge and the fresh charge. This reduces unburnt fuel lost during scavenging. The result is more torque through a wider RPM range and about 20% less fuel consumption compared to older non-M-Tronic saws.

Honest Downside

This is one of the most expensive top-handle saws on the market. The E-clip holding the sprocket is a nightmare to change in the field—if it pings off into the brush, you are done for the day. The air filter cover plastic latch feels clicky and could snap in sub-zero temperatures. If the M-Tronic chip fails, it requires a dealer diagnostic.

Who It Is Best For

Professional arborists who need the most refined, powerful, and balanced climbing saw available today. If you are a homeowner, you are buying a Ferrari to go to the grocery store.

Chainsaw Safety

Top-handle saws demand rigorous safety discipline. The chain brake on the MS 201 TC-M is inertia-activated and sensitive—this is a feature, not a bug. Always engage the chain brake when moving through the canopy.

For comprehensive safety protocols, see our chainsaw safety guide.

Maintenance and Serviceability

Spark plug access requires a single screw on the top cover. The HD2 filter is water-resistant and washable with warm soapy water. The captive bar nut on the sprocket cover is one of our favorite features—you cannot lose it.

Gas vs Battery

The Stihl MSA 220 T is a beast but heavier when factoring in the battery. For quick pruning in residential areas where noise is an issue, battery is excellent. For full-day commercial removal, the MS 201 TC-M still wins on power-to-weight and uptime. Read our gas vs electric chainsaw comparison.

Final Verdict

After years of testing every top-handle saw that hits the market, we keep coming back to the MS 201 TC-M. It is the most refined, powerful, and balanced climbing saw available today. While the Husqvarna T540XP has slightly more raw displacement, it feels bulkier in the hand. The Echo CS-2511T is significantly lighter but lacks the grunt for larger limbing tasks.

The Stihl MS 201 TC-M is the Goldilocks saw. It is just right.

Frequently Asked Questions

What fuel mix should I use for the MS 201 TC-M?

Always use a 50:1 ratio of high-quality 89-octane unleaded gasoline and dedicated two-stroke air-cooled engine oil. Stihl HP Ultra is recommended. Since M-Tronic is sensitive to fuel quality, ethanol-free gas will significantly extend the life of fuel lines and the carburetor.

My MS 201 TC-M will not start after sitting for a month. What do I do?

The M-Tronic system needs to re-learn its environment. Put the saw in the Start position, engage the chain brake, and pull until it fires. If stubborn, perform a Reset: start the saw, let it idle for 90 seconds, then make five uniform cuts at full throttle. This recalibrates the chip.

Can I put a 16-inch bar on this saw?

Yes, but we do not recommend it. The 201 TC-M is perfectly balanced for a 14-inch bar. A 16-inch bar makes the saw nose-heavy and puts unnecessary strain on the 35cc engine when cutting hardwoods like Oak or Hickory.

How often should I replace the spark plug?

In a professional setting, swap the plug every 100 operating hours or at the start of every season. If the saw stutters at high RPMs, the plug is usually the first culprit.

Why does my chain keep coming loose?

New chains stretch. If an old chain is coming loose, check your bar nuts and tensioning screw. Also ensure you are not running the saw dry—a clogged oiler causes friction-induced heat that expands the chain metal and makes it sag.

Is the M-Tronic system reliable in the long run?

Yes. Early M-Tronic 1.0 systems had some solenoid issues, but the 3.0 version in the current MS 201 TC-M is bulletproof. Most electronic failures are actually just clogged fuel filters or bad gas.

How does this compare to the battery-powered Stihl MSA 220 T?

The MSA 220 T is heavier when factoring in the AP 300 S battery. For quick pruning in noise-sensitive areas, go battery. For full-day removals in the woods, the MS 201 TC-M still wins on power-to-weight and uptime.

What is the best chain for this saw?

We recommend the Stihl 3/8" Picco Super (PS) full-chisel chain. It cuts significantly faster than the Picco Micro (PM3) safety chain that comes standard. Be aware it is more prone to kickback, so keep your wits about you.
