Rated 5 out of 5 by Very easy Starting I just got the 660 mag after x-mas (about 1 month now). I have only used it a few times..actually just got done cutting down a 3' diameter red oak tree. I love the saw, but it is a little heavy#I needs to be heavy for all the power# It starts very easy in the cold. It has been around 0 and when it is cold 4 pulls and its running...amazing. Hope it stays this way the rest of its life. GO BUY ONE February 12, 2014
Rated 4 out of 5 by Love this saw it has great power. Just bought this saw and it is a power house. I own a Husky 272 XP about 5 hp and the difference is very noticeable in power. My first cut was on a 4ft diameter red oak . I'm using the 25 inch bar and the cut was fast and straight. I find with the power the cuts are fast and fuel burn is less than the Husky. Two thumbs up for this saw. The weight was noticed at first but once I started using the saw then the weight was not a factor. Stihl did their home work on this unit. January 27, 2014
Rated 5 out of 5 by The best pro saw I've used. I love powersaws, Ive cut professionally for 13 years with many saws. My 660s are the fastest and pull chips on a 36 or 42" bar 6-8 hours a day, day in and day out. Theyre not too heavy and very reliable. Really hoping they arent discontinued. January 17, 2014
Rated 5 out of 5 by 660R STIHL Chainsaw Gets the Job Done This is a great chainsaw. It has proven that it is reliable, powerful, easy and fun to use. We bought this tool for my wife to use and she loves it, overall. The only downside for her is the weight. Our property has a lot of trees that were destroyed by the fire in our area. Over the last few years, we have been taking trees down as they have proven to be a danger to either structures or lives leaving the rest for the use of wildlife and providing shelter for the new trees and foliage as they develop. The STIHL MS660 has made this chore easy to keep up with over the last year. Our family can highly recommend this saw for year round use. October 5, 2013
Rated 5 out of 5 by Love the 660 I have run and owned many 66 Stihls, from the Red Light 066 to the very newest MS660, and love them all. The newer ones lack in power compared to the older ones, but that can be overcome. The things I like about my new MS660 are the new version of the full wrap handlebar, the 088 style bar studs, and the fact that it is the only pro Stihl saw to come with threaded fuel/oil caps, especially since that means the gas cap is larger than on any of the other saws. In western softwoods, even bone stock the MS660 will pull a 42" bar just fine. Hands down, I feel the 66 (regardless of which side the 0 is on) is the best made Stihl ever, and it is still almost the same as it was when it came out back in the early '90s. This is a saw that is used day in and day out to bring down a lot of timber in the Pacific Northwest, there is a reason for every feature (or lack thereof) and for every bit of the design. This saw has stood the test of time. July 16, 2013
Rated 5 out of 5 by Very Good Saw I run 660s for my full time logging job and my firewood business. I currently own three of them, two of which have the wrap handles. I have never had any trouble with any of them. They are very dependable saws. If you purchase the 660R you also get the larger clutch cover and chip deflector and it also comes with the roller on the dogs to catch the chain if it were to come off. My regular 660 did not come with these features. The one thing to keep in mind with the 660R is that the handle can make it a little difficult to get your stumps tight to the ground when your felling. Over all I really trust my 660s and I don't believe they are too heavy for the amount of power they have. July 13, 2013
Rated 5 out of 5 by Very reliable. Depending on cap, fueling is easy. I believe in my 66. Very good for felling trees, bucking and cutting fire wood. Used on all summer last year. High school student use it for bucking contests in forestry. May 25, 2013
Rated 5 out of 5 by All the power you need Tons of power all the way through the power band. Weight is a bit heavy but thats what you get with a 92cc saw. I run a 32" .063 Oregon reduced weight bar with full wrap. When you pick up saw by handle its perfectly balanced. Also got a 42" Oregon bar with .063 full skip chain and 660 spins it no problem even if whole 42" bar is in wood. Added the OEM stihl dual port and, maxflow filter, oversized dogs, pro safety aftermarket full wrap, then tuned carb and I couldnt ask for a better felling/bucking saw. Bit pricey but well worth every penny. March 20, 2013
