Chain saw / hedge trimmer hybrid.

it seems to me that brush cutters from Stihl, Husqvarna, etc. equipped with saw blades (e.g. Trimmer & Brushcutter Cutting Heads and Blades | STIHL USA) are designed for that task.

I have a Stihl Kombi with a brush blade in it... I regularly take down honeysuckle and buckthorn with it up to about 2" diameter... best part is I don't have to bend over to do it. The Stihl brand blade is extremely durable, even when occasionally hitting dirt.

I also have the Power Scythe attachment, but that is for tall weeds, not brush. The string trimmer head with a brush blade works the best. Gotta have a pretty powerful string trimmer to handle it though.
