"I have A LOT of blackberry, old forsythia, and brambles to cut; the thickest of which is probably 1.5". I wanted to purchase a brush mower but mowers such as DR's, Billy Goats, and Simplicity are pretty steep; even a used Billy Goat is around $900 in my area."
Look for an old Moz-All. If you take off the side skirt it converts from a mulcher into a VERY aggressive brush cutter. The engine is immune form blade impact damage decelerations because, like the DR, it is belt driven. I've used one to cut off ridiculously thick plants.
The DR brush cutters appear to me to be inspired by Moz-All's earlier design, but the DR can't convert into a mulcher as Moz-All did.
