MS 251 WOOD BOSS® is rated 4.3 out of 5 by 360.
Rated 5 out of 5 by from Easy to use The MS251 is a great machine.I feel very comfortable with it. I have the wood boss with an 18 inch chain. It just kept cutting with no jamming or kicking. I was amazed how it went through a 32 inch diameter stump in no time at all.The cut around the stump was fairly even.I went through 2 Pine stumps about 32 inches diameter,2 Locust stumps about 16 inches and a 24 inch Gum tree stump with the same blade and it still kept going with no problem.The last Stump was a 30 inch diameter Pine that was still a bit damp and the chain started to dull.Not a bad performance for an impressive first time with this saw. I recommend it.

Rated 5 out of 5 by from This is a handy compact chainsaw Used the saw extensively for two weeks after the purchase and it has performed flawlessly. Starts easy, is light enough for long hours of limbing trees and has enough power to fall trees up to 24" (mine has an 18" bar). I was even able to cut rounds out of larger tree trunks (+/- 30").The chain adjustment was simple, as was re-fueling and oiling with bar oil.

Rated 1 out of 5 by from Hard to start Hard (ie won’t start). Used it once. Was hard to start out of the box. Wouldn’t run at idle. Adjusted carb as directed to keep it running at idle, but still wouldn’t idle. Now, 4 weeks later, it won’t start period.

Rated 5 out of 5 by from Better than expected! So much better than I could have hoped for. Power for days, and very efficient, both in terms of fuel and in making short work of any project.

Rated 5 out of 5 by from Amazing saw for the price Got this saw when a buddy of mine had 4 trees blow down in his yard. Got to his house with a husquvarna and that was a joke. Went to the Stihl dealer told the salesman what I was doing and he said this saw here is the one for you and man was he right. Im only 22 years old but this saw is light and the vibration control system it has is amazing. My buddies dad has this same saw and his is 5 years old and you can tell a huge difference in the vibration in the saw after running it for 30 mins. My buddy and I cut those trees up in 2 evenings after work and loaded up a 16 ft long 6 ft wide trailer with wood 4 times. The saw performed flawlessly. The bad thing is it burns fuel like crazy. I wish Stihl had put a bigger tank on this saw. Also if you plan on cutting up more than one mature hardwood tree definitely buy more chains it will make life easier in the long run. I could go on about this saw all day. Overall just an amazing saw and it cannot be beat by any other brand.
