Rated 5 out of 5 by best choice of saws My wife bought me this for Christmas and it has cut down my cutting time by over 50% ...I sold my off brand saw and moved up ...the duel port muffler is extra power and let's the neighbor know my Stihl 660 is running! This cuts through 25 bundles of wood so fast its amazing...the .404 chain and 25 inch bar makes me smile every time I use it...a load of logs just seems to be a wheelbarrow size when this saw chews through it so fast! Thanks STIHL! May 26, 2013
Rated 5 out of 5 Ultimate Saw! I originally had a MS390 with good success but wanted a saw with more power and faster cutting ability. I chose the 660 with a 28" bar and it's become my favorite saw. I added a factory dual port muffler and it woke up even more. I also use a stihl tach for precise carb tuning if needed. I found out a full skip-tooth chain works better with the 28" bar. I mostly use it for firewood cutting and clearing trees from storm events on my hunting lease. Torque is what I wanted and I highly recommend this saw if you need to use a 28" + length bar.

Rated 5 out of 5 by This saw is a beast I've been a proud owner of stihl products for many years I purchased this chain saw a little over a month ago I looked at other brands of chain saws and none could hold a candle to the stihl also great dealer support was a major factor in this purchase as well this chain saw has tons and tons of power I'm running a 36" bar cutting red and white oak around 34" in diameter at the base and this saw just absolutely destroyes anything that it encounters I'm really impressed at the power this saw has and the more you run the saw the stronger it gets as it breaks in this is a very large and powerful saw I would not recommend this saw to the comon homeowner but for a professional who wants quality power and reliability I'd say buy it it's simply a beast March 22, 2014
Rated 5 out of 5 by Power!! This is my first big saw. It is also my first Stihl saw. I cannot begin to explain how quickly and smoothly this saw will cut. It is remarkably light for its size. I have been quite a few full days with it now with no problems. It does drink gas! I use a lot of bar oil too, but I have the oiler turned up as high as it will go for the application I am using it for. The first thing I cut with it though was a 4ft diameter yellow poplar. I was using the 36" bar and 33rs114 stihl chain. It cut through it fast. The saw never bogged down at all in the poplar. The real test will be cutting through a live oak or white oak of the same size. This saw is a robust piece of equipment, and I am very happy with my choice. I purchased this saw to be primarily used for milling. I am running a 36" Stihl bar with a 3/8-.50"-114DL ripping chain. For milling, the ripping chain is a must, and I really wish Stihl manufactured a ready to use ripping chain. March 12, 2014
Rated 5 out of 5 by Incredible Chainsaw I recently purchased my MS660 after having looked at the competition. I chose Stihl due to the several factors. The power to weight ratio is awesome this allows you to get the most out of the 90 plus cc power. The easey filter access not to mention the standard heavy duty filter, which if maintained is reusable. The MS660 clearly puts Stihl in a class of their own. I have found this saw to perform beyond my expectations. Whether I am felling trees or slabbing wood on my portable mill, I have been pleased at every task. March 3, 2014
Rated 5 out of 5 by Love the MS660 and you will too! I bought my MS660 about 3 years ago after some tornados tore down some trees to big for my MS290 to handle. I absolutely love this saw! It really handles BIG WOOD with no problem! It's NOT for a beginner/ greenhorn ! I have a 25" & 36" bar for mine and it handles both very impressively. If you are looking at a MS660 and not sure if it's worth that much cheese I would say Yes! If you buy one you'll be glad you did! I have the value at good because it is a bit pricey, but as always it has the dependability you would expect from Stihl! February 24, 2014

Rated 4 out of 5 by Great saw could use some upgrades Great saw, i use with 36" bar, 7 tooth sprocket, mainly for bucking large hardwood, i did change the muffler casing from the pencil eraser size output to the thumb size output and added HD2 filter, retuned a little richer, and sounds and works great, except with oiler that puts out less than my old Husqvarna 394, i definitely had to switch to winter bar oil when it gets cold or it won't oil good enough. I guess some replace the oiler with the higher output. The Husqvarna 394/5 may have slightly more power, but is also heavier, and has the outboard clutch, whereas the Stihl is easier to change chains. Very durable saw, i have original 066 that are 20 years old and still run after serious abuse. I am looking forward to 661 mtronic release that will be smoother AV but good to have this in stable.
