I have owned a 462 for just over a year now.
I am not a professional logger or arborist but I have done a lot of work with this saw.
In October of this year me and a friend cleared over an acre of Noble Fir. I was cutting and he was hauling the logs out.
I also cut a lot of wood for my dad (falling, bucking etc) who owns a Sitka plantation. A lot of that work is cleaning up blowdown patches.
I agree that the saw is not the torqiest machine I have ever used but the light weight and high power with anything 30' or less makes it a joy to use. I especially like it for blowdown patches where I have to often climb over logs, jump out of the way of loaded logs and just avoid getting hurt in general lol. Having a saw light enough to swing around with ease and still use a long enough bar to not have to get too close to what you are cutting is a real pleasure.
HOWEVER, I know what you guys are saying about Stihl's recent "ideas". Why do their 70 and 80cc saws cave such tiny felling dogs? Why are wrap handle bars so hard to get as stock, why the flippy caps, why such restriced mufflers, why the one piece top covers that make it hard to install bigger air filters etc etc.
As to stihl dealers, well I never buy saws or have repairs done by my local dealers. They always charge as much as they can and take ages to get anything done and if you dont call them about your saws then they will just keep the damn things.
I traveled 25 miles to another dealer to buy my 462 in November of last year. Ended up walking out with a 462, 261c and 193t for €2000 and the guy through in bar oil, HP oil and a stihl helmet for free.
here's some pics of my 462 in action.
I have found this saw best suited to a 25' bar. I have had this saw bury a 25' bar and full comp chain with only half an inch sticking out on the other side of the log and didnt experience any bogging unless my chain was dull. A 30' bar and chain doesnt cut so good but I would love to try a full skip chain but unfortunately they are hard to get around me.
Cant speak for the 572 but it looks and sounds good.
