My 572 only has 15 tanks run through it, cutting a mix of fresh black cherry and dead dusty Ash. The filter definitely lets in fine dust, I would say so far that's the only thing I don't care for. Husky nerds to update the filter material it's not up the level of other manufacturers right now, 30 years ago it was the best out there.
Those paper HD filters and filter neck on the 7900 kill the power in my experiences compared to the low top filter, not enough flow. Not as easy to clean or flow as well as a oiled foam filter. I’m surprised none of the manufacturers have come out with a oiled foam filter.
The 7900 filter does seem to hurt power a little, but dust doesn't seen to get impregnated in to the filter media much. The oiled filters work great but can be messy, and most likely wouldn't take care of them properly. The bigger issue with the 7900 HD setup was the pre-filter, it would clogged up in no time and you really couldn't clean it without soap and water. So far tye 7900 filter is the only one filter I've seen that doesn't let anything in, the Stihl 261 was a close second.
I’d like to hear what John says when he finds a random pile of cookies in the woods...lol! Nice running saws Mason.
I figured he’s used to the “science” by now...lol!
I agree. 462 is as fast or faster no question and it is lite... but I felt it was lite on torque... felt like I was fussing with the chain more often than the 572 to keep it cutting well.
Don’t expect much from it new and stock... till you get about a gallon of fuel thru it. The software apparently has a “break in” program. From my experiences it kinda makes it sluggish until it reaches a certain amount of hours.
