Really like the .404 chain and Bar combo , installed it on my MS661 ! Makes it cut a lot faster and shouldn’t have to worry about breaking any more chains
I’ve been cutting for 30 years now give a take a little time off…I can’t sharpen my saws as frequently as I used to so this 404 really helps keep an edge longer. I used to have to dress the chain every 3 or 4 tanks…now I can make it through an entire day of cutting and go home and sharpen in my vice. Much easier on my back than doing it in the field. Wish I would have known about this years ago…Thanks RIPSAW. Great people, great service, tons of knowledge…
I ourchased a 661 from these guys…they told me it would have more power than I could imagine and man did they deliver!! I run 28” bar and chain and the saw has so much torque it was stretching my chains in hardwood. They recommended the “big tooth” kit and man am I glad I picked one up. The 25” bar is great for plunge/ bore cuts and this is primarily what I do being a tree feller. Thanks again Ripsaw y’all know your shit! Can’t wait for my 881 build!!
