Husqvarna chainsaw model numbers identify different saws, but the name alone doesn't tell you every spec. Compare engine size, bar range, weight, and features to find a model that fits your work.
The 120 Mark III and 435 have 16-inch bars, while the 450 Rancher and 455 Rancher have 20-inch bars and larger engines. Their specs are more useful for comparing them than assuming a higher number is automatically an upgrade.

Bar range and weight matter too. Compare them with your planned work and the saw's instructions.
