I do mine with a file by hand as well and take down the rakers from the get go then a little every other sharpening. Also like to use more aggresive chain from the dealers, what a difference. Just bought a new saw a few months ago . Husqvarna 555 auto tune god what a saw. My favorite Husq 350 went to heaven. Is there a chainsaw section on here ?? Hint Hint . Buddy just bought a husq 272 pro and a 4k lb winch to hook to it were gonna try it out this weekend. Ive never used or seen a chainsaw winch have you guys?
