It’s an absolute beast!

I was like a kid waiting 8 months for Christmas to get this animal in my hands. Well worth the wait! I live in the Ozark mountains of Arkansas, and the beast has not met her match yet. I run a 36” with absolutely no issues. Great at felling and rips with amazing ease! The RipSaw team are mad scientists and have built something special. I have ran 15 gallons of fuel now with zero issues. Save yourself some regret and get this, you won’t be disappointed!

Best felling saw

Best felling saw on the market. Great on fuel, and pull 36” full house like it’s a 20. Every faller in my area that has tried it now wants one. I’ve worked this saw for over a year now I’ve waited to give this review. Very strong saw. Zero issues. These gentleman know how to build a work saw.

Blacked Out Stihl 661

I needed a more powerful saw than my Husqvarna 460 to fall, and cut bigger timber, so I started looking at the bigger huskys and stihls online and stumbled upon ripsaw. I bought the blacked out Stihl 661. This saw is absolutely amazing and worth it! Aside from the compliments on its looks, the timber fallers in the park love the sound and can tell it is Mean. I have been falling and cutting 36" - 38" wide 100ft tall white furs and pines with a 36" bar and this thing just rips through these trees. Ripsaw has this 661 dialed in perfect! I'm at 5100 ft Elevation in Northern California and the saw runs amazing.

Ripsaw 661 Mag

This 661 was knocked out the park. It’s everything I wanted in this 661. It’s mean, powerful, and feels good. Revs up quick and nothing will make it bog. I know there a lot of good porters out there but I won’t have any of my saws ported elsewhere. Glad I found these guys at Ripsaw. Awesome professional work with lifelong support. What more can you ask for !? Looking forward to my next Ripsaw 🇺🇸
