Conclusion: Reviewers say the Husqvarna 450 offers plenty of muscle without being too heavy to maneuver. It's not perfect, however; a few owners complain that it can throw its chain, and the tensioner requires a wrench to adjust. Still, this saw is fast, durable, easy to start and powerful enough for a 20-inch bar.
Pros: Fast, powerful, Relatively light, Easy to maneuver, Starts easily
Cons: Sometimes throws chain, Can plug with sawdust
