Rated 5 out of 5 by from Beast of a saw Originally bought this saw for milling,but decided to use it for my felling needs and I've never looked back Im pretty sure I'll never come across anything this saw can't handle.ive ran 066 and 660s and this saw is way above them as far as power and torque and the m tronic take the guess work out of tuning and adjusting for conditions.its been very reliable so far usally two pills and it fires right up.Thos is most definitely a pro grade saw,I had to order mine cause trees companies in my area bought my dealer out.truly the best saw out of the 4 Stihl saws I own and it definitely kept the Stihl reputation up as being the best .thanks Stihl!!!

Rated 5 out of 5 by from Alaskan mill powerhouse I bought this saw to run a 36" Granberg mill through hardwoods. I put a 42" bar with ripping chain on and the mill gives a touch over 33" of cutting width with that set up. The widest I've had a chance to cut has been about 28" over short runs, with sustained cuts out to about 20". With a sharp chain the saw walks through all that without a second thought. I'll be taking down a big maple soon and working the mill at max width all day on it, I'll update my review once I do. My only complaint with this saw is it can be a little finicky to start when it's hot, but we just find clean up tasks to kill 30 minutes and it fires up first or second pull once things have cooled down. That or just hold the throttle wide open rather than using the automatic Start setting. The details on this saw are great too - love the fuel caps, love the easy adjust chain tension, love the embedded bolts on the chain retainer plate so we aren't chasing nuts around a dirty job site. This is my first Stihl and I'm a convert now. This is a big, expensive saw and it's a lot to throw around, but if you need the power it's your only option & it delivers.

Rated 5 out of 5 by from Great Saw I am 16 years old and make money on the side by cutting low risk trees and milling them with an Alaskan Mill into lumber to sell. I am by no means an expert but have a decent idea what I am doing. I love my 661! I purchased it right after Christmas in 2015. The 661 typically runs either a 25" or 36" bar with 33rs3 chain and is unstoppable even in the most gnarly wood. The balance of the saw is great but I find it to be perfectly balanced with a 25" bar. The 36" gets a little nose heavy but keeps the saw very nimble and maneuverable. A little expensive for me, but it continually proves it is worth every penny. On a side note I was cutting some trees for a farmer and got hung up in a gum tree by a gust of wind. As I walked back to the truck to get a wedge and saw tool the wind stopped, my saw fell out of the kerf, and got smashed by a 22" gum tree. This saw is so well engineered that similar to the front of a car folding like an accordion in an accident, the top handle on the saw folded like an accordion and absorbed the force of the tree. A few weeks later the saw was back up and cutting wood again.

Rated 5 out of 5 by from Strong Running Machine We have a new in ground pool, and had an old, large Poplar tree in the back yard. With this huge tree, the pool was going to stay full of leaves, all the time. It had to go. I needed a saw powerful enough to take this tree out. I did some research, and off I went, to purchase the king of saws. I was after the Stihl MS 880 Magnum. I looked in several stores, and nobody had the 880 in stock. Then I found the MS 661 C-M, with a 32 inch bar, and a skip tooth chain. This thing is a beast. It ate that Poplar tree for breakfast, and even ate a Cedar tree, that got too close to it. When I was done, it was looking around for more. Way to go, Stihl !

Rated 5 out of 5 by from Great saw I bought the saw because my old farm boss couldn't keep up with the clean up from hurricane matthew. I have not been disappointed once by this saw. It takes down trees in a hurry. Wind blown pines, white oaks, and large gum trees. Some of those oaks were 44 inches and against a 36 inch bar with a full skip chain, not a problem. My saw runs great but recently I started thinking it could be better. I sent it to a west coast faller and it is now a Magnum Insane-O Magnum. Check his 661c on youtube. hotsaws101 it runs like the terminator on steroids now.

Rated 5 out of 5 by from Powerhouse This saw is an animal. 36inch bar burried in an Oak and the saw pulled like it was wearing a 25inch bar in a maple. Crisp smooth power. A real head Turner when you open it up on a job site.. starts amazing just a great saw.
