I guess I just wanted to take the time to make my first post and say hi. LOL I heat my house with a wood burning stove and cut 4-6 cords a year. My current saw battery: Stihl 180. (3-4 years old) Husqvarna 440. (7 years old) Husqvarna 445. (9 years old) I have a new addition to the family. I have been bugging my lovely wife for a bigger saw for a couple of years. After I cut down an Oak tree the beginning of this month that was 36in at the base with my trusty 445 Husqvarna, she agreed. So now I have a Stihl 391. I wanted the 362, or even better the 462, but they were out of my price range. I love the 391. I have had it for about 1 week and I have already put over 10 hours on it.
