With hundreds of trees on my property, I'm constantly managing growth, clearing dead trees and removing invasive species. I tested the Husqvarna 455 Rancher chainsaw and it was up to it all.
They refer you to a Husqvarna dealership but they can't help out much neither as far as I'm concerned unless, if you know how to maintain your own saws that's the only time to purchase a Husqvarna.
