The Stihl MS 170 is a small chainsaw with a 30.1 cc motor that has a power output of 1.5 kW and weighs 4.1 kg (9.0 lb). The saw can be used for felling small trees, cutting firewood and general garden maintenance.

The MS 170 is best suited for cutting firewood or general clean-up tasks around your home. If you want something easy to carry around while working outside your house during winter months then MS 170 might be better option because it has lighter weight than MS 180 which makes it easier to transport over long distances without causing fatigue or muscle aches.

MS 170 Vs MS 181

The first difference is the engine displacement. The 170 has a 31.8 cc engine whereas the 181 has a 38.0 cc engine.

The MS 170 and MS 181 are both STIHL chainsaws, but the 181 is a newer model that has some additional features. The most notable difference between the two models is the engine displacement, which can affect the power of the chainsaw. You should also consider the weight of each model, as this can affect how easy it is to use and maneuver.

The MS 170 has a 1.8 horsepower engine and a 2.2 cubic-inch displacement while the MS 181 has a 2.3 horsepower engine and a 2.7 cubic-inch displacement. The additional power means that the MS 181 is more suited for cutting hardwood logs and larger trees than the MS 170, although both models can be used for general yard work, including chopping up tree branches.

STIHL MS 170 vs MS 181|Power output

Power output is an important consideration when comparing any two chainsaws. Generally speaking, it takes more power to cut larger trees or do bigger jobs faster, so if you’re planning on tackling big projects, you’ll want higher horsepower.

While it might not be much of a difference in terms of power output, having a longer bar means that you can cut through larger pieces of wood with less effort required from you as compared to using a shorter bar for cutting through large pieces of wood.

The STIHL MS 170 and STIHL MS 181 are both light-weight, compact chainsaws that will help you get the job done. The STIHL MS 170 is great for trimming and pruning small shrubs and trees, while the STIHL MS 181 is a step up in power and size from the STIHL MS 170.

Power-to-weight ratio: Based on measurement of the power output at the engine and the weight for each chainsaw model.

The MS 181 has a slightly more powerful engine that produces 1.5kW. It also has a slightly higher weight of 4.4 pounds, making it less lightweight than the MS 170. Second, let’s compare the design of both chainsaws. The MS 170 has an ErgoStart system that helps reduce pulling effort by up to 40 percent and a manual fuel pump for easy starting.

STIHL MS 170 vs MS 181|Sound pressure level

The biggest difference between these two chainsaws is their sound pressure levels (SPL). The SPL is a measurement of how loud something sounds when it occurs at 1 meter from its source.

The STIHL MS 170 and MS 181 chainsaws are two of the most popular models on the market today. They’re both great machines, but there are some differences between them that you should be aware of before making a purchase. The MS 170 and MS 181 have very similar features and specifications.

STIHL MS 170 vs MS 181|Sound power level

The Stihl MS 170 has a sound power level of 109 decibels. The Stihl MS 181 has a sound power level of 112 decibels. As you can see, there is only a slight increase in noise from one saw to another—this may not seem like much, but it can make a big difference when you’re using your chainsaw for extended periods of time or in an area where loud noise is not allowed.

The MS 170 is part of STIHL’s lightweight compact chainsaw family. This unit weighs in at a mere 10.6 lbs., making it the lightest gas powered chainsaw in the STIHL line-up.

The MS 181 offers some upgrades over the MS 170 including an advanced anti-vibration system that reduces operator fatigue, and STIHL Easy2Start™ technology which makes starting the saw effortless. While this unit is more expensive than the 170, it provides more value to the user thanks to these upgrades and its increased fuel efficiency. 

STIHL MS 170 vs MS 181|Vibration level left/right

MS 181 has a vibration dampener that reduces vibration on the right side of the machine.

Both saws use an auto-return stop switch to protect against accidental starting when not in use; however, only the MS 181 has an anti-vibration system for reduced vibration on only one side of the saw (left).

The vibration levels of these chainsaws are similar. If you’re just casually handling them, the difference won’t be noticeable. But if you’re working with them for several hours on end, it might become an issue. The MS 181 has a slightly lower vibration level than the MS 170, but only by about 0.5 m/s² (0.15 ft/s²). That’s not a big amount at all and shouldn’t affect your decision significantly. Safety features The MS 181 has a chain brake which stops the chain from turning when you release the trigger or engage the chain brake handle.

It has a vibration level of 1 out of 5 which means it’s one of the most comfortable chainsaws on the market today. The MS 181 has a vibration level of 3 out of 5 but still not as high as other models that can reach up to 7 or 8 out of 5. 

STIHL MS 170 vs MS 181|Saw chain pitch

The first thing to consider when choosing between these two chainsaws is the chain pitch.

The MS 171 has a 20″ bar while the MS 181 has an 18″ bar. The shorter bar on the MS 171 makes it easier to maneuver around trees and other obstacles when you’re working in tight spaces, but it also means that you’ll have to sharpen your chain more often than if you had an 18″ bar on your saw. Both of these saws are designed with comfort in mind, so they’re easy to use for long periods of time without getting sore arms or wrists from holding onto them too tightly or straining yourself trying to cut through thick branches or logs with each stroke of the blade instead of.

STIHL MS 170 vs MS 181|which is more better

The STIHL MS 170 has an engine that produces up to 3 horsepower while the STIHL MS 181 has an engine that produces up to 4 horsepower. This means that the MS 181 has more power than the MS 170, which means that it can cut through thicker pieces of wood faster than its counterpart.

The STIHL MS 170 is a great chainsaw for anyone who needs a powerful, versatile tool that can handle just about any job. It’s a great choice for clearing brush and firewood, but it also has the power and control to handle heavier tasks like felling trees and limbing.

The MS 181 is one of the most popular models in the STIHL lineup, so it’s no surprise that there are a lot of similarities between the two saws. Both are lightweight, easy to start and have excellent ergonomics.
