The lighter unit is also easier to hold above your head when you’re cutting branches in trees or making other cuts that require vertical positions with the saw.

STIHL MS 181 C-BE vs MS 251|Power-to-weight ratio

The STIHL MS 181 C-BE and STIHL MS 251 are two popular chainsaws from the STIHL lineup that can be used for a variety of tasks like woodcutting, yard work, or general maintenance. While both are easy to use, lightweight and powerful, there are some key differences between the two that may influence your decision to purchase one over the other. The power-to-weight ratio is an important figure to consider when shopping for a chainsaw. It measures how much horsepower you get out of each pound of weight, which is important because it will tell you how much power it takes to cut with each saw.

The MS 181 C-BE has a power-to-weight ratio of 2.62 pounds per horse power (lbs/hp), while the MS 251 has a power-to-weight ratio of 2.31 lbs/hp. This means that the MS 251 is heavier than the MS 181 C-BE for the same amount of horsepower, so if you’re looking for a balance between power and weight, you may want to consider going with the lighter option.

STIHL MS 181 C-BE and STIHL MS 251 are both mid-range chainsaws in the STIHL lineup, with many features that make them a good choice for homeowners. The biggest difference between the two is their power source: MS 181 C-BE uses gasoline and MS 251 uses a battery. STIHL’s battery-powered chainsaws are great for those who want a quiet alternative to gas models, but still need plenty of power for medium jobs around the yard.

Beyond their power sources, there are some other differences between these two models worth considering before you buy: Sound pressure level – Gas chainsaws are typically louder than battery models, but how loud? To measure this, we use sound pressure levels (dB). In general terms, anything over 85 dB is considered excessive noise exposure. The MS 181 C-BE has a sound pressure level of 108 dB compared to the MS 251’s 90 dB.
