Rated 5 out of 5 by from Should have bought a long time ago Great saw. Idles wonderfully. Cuts like butter. Not too heavy. Starts easily with very little force required. Love the ability to adjust chain tension without tools.

Rated 5 out of 5 by from Nice upgrade. I went to the Stihl dealer with my mind set on the Farm Boss and ended up buying the lighter duty MS 251 C-BE. Personally, I cut and split approximately 3 to 4 Federal cords of wood each year around our 15 acres. This saw motors through red oak with no problem. At first, I was having issues with starting the saw but it was due to not following the recommended starting procedures. The quick chain adjuster is very convenient and has not given me any problems. I will probably appreciate the weight of this saw as I age.

Rated 5 out of 5 by from Great chainsaw for commercial or private use In my younger years, I was a line clearance tree trimmer and I also did a ton of sidework trimming and removing trees of all sizes. We used a lot of Stihl chainsaws including the 011T, 017, 036 and 044. This new generation of chainsaw is all of what the older saws were and more. The easy start feature and easy chain tension adjustment feature work excellently. I've spent several hours removing trees on my property from 2" diameter all the way up to 16" diameter and it easily cuts through all of them and has never bogged down or stalled. There is virtually no vibration feedback through the handles so it has been very easy to use it almost non-stop for several hours, pausing only to refill it with fuel and bar oil.

Rated 5 out of 5 by from Powerful, easy to start and convenient chain adjustment without tools. At 72, I absolutely love the easy start feature and the no tool chain adjust feature. The power and 18 inch bar length is excellent for my needs. I have a 20 year old 017 chain saw that still runs and I"m confident tha my new 251 C will do the same.

Rated 4 out of 5 by from Very easy to start and restart Too bad they don't offer this start system in all their models. The MS-250 I owned previously was a total PIA to start and restart. I followed their start and restart procedures to a T, and it was still not reliable. If I attempted to use anything other than very expensive premix, it would not start at all. This was using Shell premium and Stihl 2-cycle oil. I spent a small fortune on premix.As I said, the 251 is much better and I have not had any starting issues. I am, however, still using only the premix I purchased when I bought the saw. It will be interesting to see if this is still the case when I change over.It is just a shame they don't offer this starting system on other models. I really would have liked more horsepower, but just couldn't risk another saw with starting issues.

Rated 5 out of 5 by from Stands up to abuse This is my 1st chain saw, it has an 18" chain,. It originally cut like butter, no bucking. The 1st start easy when use the prime bubble, afterwards usually starts on the 1st pull, even after long down times. I cut out a juniper stump the 2nd time I used it & hit some dirt under & between roots & it dulled my chain; but got the stump out even with a dull chain. Chain saw OK after abusive use & a smoking chain. Point to make, it put out a lot of oil when the chain started smoking which saved the blade & chain saw. I just do not like stopping in the middle of a job & at the time had no chain files. Since I got some chain files & sharpened the chain, it is back working fine. I will never cut out a tree stump again. I was originally really afraid of chain saws, but this one is so smooth & reliable I am not scared to death using it.
