Rated 5 out of 5 Excellent Saw The Stihl 251 Wood Boss is the first chainsaw I have purchased. I was set on a Stihl after using a Stihl 290 Farm Boss that my father in law has owned for years. You get what you pay for and the 251 delivers. I have only run two tanks through it during the break in period. So while only using half throttle, it has plenty of power. The vibration reducing system is great. 4 hours of cutting and no tingly hands. It also seems to sip fuel. Very happy with my purchase. January 30, 2016
Rated 4 out of 5 by Good saw. This is my second Stihl saw. The first, an 021, was a great saw. I've owned this current Wood Boss for 9 months and it is as or more powerful than the 021, but I believe it's a little bit cheaper built. The biggest complaint I have about the Wood Boss is the single chain-tightening bolt. I'm having a heck of a time keeping the chain tight and I'm afraid to really crank down on the tightening bolt head as it has a plastic grommet looking thing around it. Other than that, the saw is powerful and cuts like a demon. It cranks right up, usually on the second pull when cold, first time when warmed up, and I really like the easy-fill oil and gas tank covers. December 12, 2015
Rated 5 out of 5 by MS 251 WOOD BOSS I was looking to buy a saw so I could cut some fire wood and smoking wood. I searched and searched red reviews and all that jazz. I went to a local ace hardware that was stihl dealer and the salesman who also happened to be there mechanic took the time to go over this particular saw with me. After I decided to buy it he took me in the back to his shop and filled it up with gas an bar and chain oil. He started it and tuned it and got it running perfect (it didn't take much). I took it out today the same day I bought it and cut a truck bed full of oak and this saw did phenominal. Never had one issue with it. I ran it hard and never had a problem restarting it. I am very pleased with this purchase and glad I went with a stihl December 10, 2015
Rated 5 out of 5 by Shil 251/Wood Boss Needed a saw, could have done the less expensive, or gone cheaper (route). But I got a Sthil. I needed to trim the 3 large oak trees in my yard. I got the Wood Boss! Well the chain saw DEFINITELY lives up to the name. I used all of the recommended products from the dealer in Deer Park, TX. I purchased the bar oil, fuel oil, lanyard, extra chain, sharpening stone (dremel) and carrying case. Great service, great product. Reliability is the best, I had a bit of trouble starting out but the dealer advised me over the phone and I was underway in no time. The built in safety feature on the Stop-bar, was much appreciated while I was 30 feet at the top of a ladder (while tied off). It prevented me from hurting myself. Great reliability, great fuel economy, and a well designed safety feature. December 6, 2015

Rated 5 out of 5 by This saw worked me We just had an ice storm come through, needed a new saw, so I decided on this one. Used this one first day, and it was great. Plenty of power, easy to operate easy to handle. Very good product. December 1, 2015
Rated 5 out of 5 by Meets my needs I own a Pecan tree orchard and it's a normal event for limbs to fall or for trees to be trimmed. I've had the pleasure of using this saw for an entire year and it has met my expectations, fully. Limbs can be anywhere from 4 inches to 25 inches though, this saw is never too heavy to handle. Only on one occasion did I have an issue with getting it started however, I blame myself for getting into a hurry. Aside from that one episode, it has been flawless. Some would disagree to this but, I run STIHL's Moto Mix fuel only. I do so because there can be periods where the saw could sit for more than 2 months - guess I'm paranoid. Overall, this is probably the best saw for light to medium work. November 30, 2015
