Hello everyone. With the fall approaching I am looking for a new chainsaw. My Dad, Uncle, and myself all cut wood together during the winter as we all heat with wood. Few years back I bought a homeowner grade Husqvarna 450, Dad has an old McCholloch Pro Mac 610, and my uncle has a Husqvarna 61. I am looking to upgrade my saw. I'm keeping the 450 and will replace the 20" bar with an 18 probably but need a saw that's happy running a 24" B&C all day long and will happily run a 28" as well. I will also need to use a 32" at times but that will be more rare. The 24" and 28" will mostly be what I'm running. I have narrowed it down between these 3 and wanted to see what you guys think. Husqvarna 372XP, Husqvarna 576XP, Husqvarna 390XP. I know with the 390 I would probably never want more power but that's going to be over $1,000 out the door which I will do if need be because this will be the last saw I buy for a long time. Any opinions would be great. Also my 450 is rated at 3.2HP, the 372XP is rated at 5.5HP. How much difference with a chainsaw does an extra 2HP make? The 372XP is lighter than the 390. If later i felt I needed more power I could get it professionally ported. Then have more power still in a lightweight package. Also for the info I mainly cut hardwoods, mostly red and white oak.
