The MS 170 is a light, powerful chain saw for homeowner use. This unit is ideal for cutting firewood and for light clean up tasks around the yard. It features a high power-to-weight ratio and STIHL anti-vibration technology to reduce operator fatigue. The MS 170 also features redesigned ergonomics that improve operator comfort, including a low vibration handle and carburetor preheating system for quicker starts in colder weather. 

Fuel injection systems use an injector to spray fuel into the engine’s cylinders instead of using a carburetor. This allows them to deliver a more precise mixture of air and fuel, which makes them more efficient than a traditional carburetor system. 

The STIHL MS 170 is part of STIHL’s popular line of homeowner saws. The smaller model in the series, the STIHL MS 170 offers excellent power to weight ratio with an improved fuel efficiency compared to previous models.

For a homeowner or part-time woodcutter, the MS 170 is a versatile chain saw that will come in handy for storm cleanup or general tree maintenance. 


The STIHL MS171 is the latest evolution of the successful MS170. With its improved performance, the new model offers a better balance between power and weight. This makes it a good choice for smaller cutting jobs. The STIHL MS171 weighs just 4.8 kg (10 lb.), which is 2 kg (4 lb.) lighter than its predecessor. The STIHL MS171 features a durable two-stroke engine that delivers higher torque at lower revs than four-stroke engines. This means you can get more work done with less effort and fuel consumption is reduced too! A LowVib system reduces vibrations at the handle by up to 95%.

This makes it much easier to use over long periods of time without getting tired hands or arms. The STIHL MS171 features an Xtra low-emission exhaust system with catalytic converter, giving it an air/fuel ratio that complies with current European emission standards. A special air filter system ensures clean air intake from the outside atmosphere through the carburetor and into your engine’s combustion chamber — preventing any dirt particles from entering your engine’s crankcase oil during operation, which could.

The MS 171 weighs about 10 pounds more than the MS 170 due to its larger engine size and additional features like an auto-oiling system.

MS 170 Vs MS 171

This makes it easier to use overall but may make it less portable than its smaller brother depending on what sort of task you’re doing with it. The MS 171 comes equipped with a longer bar than does the MS 170 (16″ vs 14″). This means that it can cut through thicker branches faster than its little brother can since there’s less resistance in the wood as it passes through them (assuming they’re not too big).

The STIHL MS 171 has been designed keeping in mind the safety of both the user and the environment. STIHL MS 170 is another popular chainsaw from STIHL Power Tools (formerly known as Echo). It features an automatic chain oiler which ensures proper lubrication of your chain at all times, thereby increasing its life and durability.

This stihl chainsaw features an anti-vibration system that reduces vibration at the handle by up to 25%. It also has a low noise level which makes it suitable for use in residential areas as well as commercial sites where noise pollution is not allowed. The MS 171 has been rated highly for its power and performance when used for cutting thick branches or logs. However, it does not perform well when used to cut small twigs or wood chips due to its large size (16″). On the.

STIHL MS 170 vs MS 171|Engine Displacement

The MS 170 has a 24 cc engine while the MS 171 has a 26 cc engine. Engine Displacement The main difference between these two models is their engine displacement. While they both have an 18″ bar and chain, one model has a 24 cc engine while the other has a 26 cc engine.

The larger displacement allows for more power from each pull of the trigger, but also increases fuel consumption slightly due to increased heat generated by the increased compression ratio of larger engines. Fuel Capacity Fuel capacity varies based on whether your chainsaw has been converted to run on premium fuel or not (see below). If running on regular 87 octane gasoline, then you can expect between 15-20 minutes worth of cutting time before needing refilling with fuel depending on how much you’re cutting down at any given time during use.

MS 170 is a high-powered, gas-powered chainsaw with a 20-inch bar and chain. It features an engine displacement of 170 cc, which helps it deliver a powerful performance. Built for professional use, the MS 170 can be used to cut branches up to 2 inches in diameter.

STIHL MS 170 has an engine displacement of 16.2cc while the STIHL MS 171 has an engine displacement of 17.2cc. This means that both machines have the same amount of power, but the larger engine means that it can handle bigger branches with ease.

STIHL MS 170 vs MS 171|Power output

Both chainsaws have an engine power output of 0.75 kW, but the MS 171 has a slightly higher maximum cutting speed than the MS 170. The maximum cutting speed for the MS 170 is 8,000 RPMs and for the MS 171 it is 9,000 RPMs. However this difference isn’t likely to be noticeable when you are using either chainsaw on trees or small branches as both machines can cut through wood at this speed without any problems.

The fuel type that each machine uses is important because if you have access to one type of fuel but not another then you won’t be able to use that particular machine until you find somewhere with that type of fuel available. The STIHL MS 170 uses unleaded petrol while the STIHL MS 171 uses 2-stroke oil mixed with unleaded petrol or diesel oil mixed with unleaded petrol.

The STIHL MS 170 and STIHL MS 171 both come with a 20.6 cc engine that produces up to 1.3 hp of power. With this powerful engine, you can easily cut through even the toughest branches and limbs. The two chainsaws also have a 14 inch bar, which gives you a lot of cutting power in one pass. Both chainsaws are powerful enough to take down large trees or branches, the 171 has a slightly lower power output than the MS 170.

STIHL MS 170 vs MS 171|Weight

The Stihl MS 170 and MS 171 are both light weight chainsaws commonly used for cutting firewood, pruning trees and other small yard work. The MS 170 was first brought to the market in 2002 by Stihl as a lighter version of their MS 180 chainsaw. It ended up being so popular that Stihl decided to keep it around after discontinuing the MS 180. The MS 171 was introduced not too long ago in 2014 as an upgraded version of the Stihl MS 170.

As far as weight goes, they are virtually identical. The Stihl MS 170 has a dry weight of 5.9 lbs while the upgrade, the MS 171 has a dry weight of 5.8 lbs. Both weights include an empty fuel tank and bar/chain oil reservoir but do not include the guide bar or chain itself.

STIHL MS 170 vs MS 171|Power-to-weight ratio

They have similar power-to-weight ratios (3.78 kg/kW and 3.66 kg/kW respectively), which means that they are both relatively powerful for their size and weight. This is useful when you need to cut down larger trees or branches in your garden, as it will be easier to control the saw when it’s light enough to hold with one hand.

The MS 171 has a larger engine, which makes it more powerful than its smaller counterpart. It also has a higher weight-to-power ratio than the MS 170, which means that it will be easier to handle because it’s more powerful per pound.

The MS 170 has a power-to-weight ratio of 0.45hp per kg. This is quite low compared to other chainsaws in its class, but it’s still enough to make short work of hardwood and softwood trees. The 171 has an even lower power-to-weight ratio of 0.27hp per kg, which makes it one of the lightest chainsaws on the market today.

STIHL MS 170 vs MS 171|Sound pressure level

Sound pressure level (LpA) is the primary difference between these two models. The MS 170 has a sound pressure rating of 98 decibels, which is about as loud as a household drill. Some states require hearing protection to be worn at this level, so it’s best to check your local regulations.

The MS 171 has a lower sound pressure rating of 94 dB(A), which is about as loud as a food blender. This means that no hearing protection is required in most states when using this saw, and you’re less likely to disturb your neighbors and other people around you with excess noise. Both chainsaws feature STIHL’s Quick Chain Tensioning system, ErgoStart technology (which makes it easier to start the engine), and have an anti-vibration system that increases operator comfort while reducing fatigue after extended use. Both saws also feature the same cutting power: 3 PS with an engine speed of 11000 rpm. This means that the two.

The sound pressure level of a chainsaw measures how loud it is to the human ear.

When you operate a chainsaw, you are required to wear hearing protection to prevent long-term hearing loss—the sound of a chainsaw can exceed 115 decibels (dB). The MS 170 has a lower sound pressure level than the MS 171 (106 dB vs 109 dB) but both are still very loud and require hearing protection.

STIHL MS 170 vs MS 171|Sound power level

The sound power levels of these two chainsaws are very close. The MS 171 has a sound power level of 98 decibels while the MS 170 has a sound power level of 97 decibels. The difference is only 1 decibel, which is not much at all. STIHL MS 170 vs MS 171|Weight and balance The weight and balance of these two chainsaws are also very similar.
