How thick of a branch can a gas hedge trimmer cut?

Manufacturer specs in the listings range from roughly 4/5 inch (Husqvarna 322HD60) to about 1 to 1-1/8 inch on the higher-capacity SENIX and PROYAMA units. Specialist-community contributors caution that real-world performance drops off fast on anything thicker than a finger, and a hedge trimmer is not a substitute for a pruning saw or pole saw on woody limbs.
