Like RalphVa said, the LX4 will handle much bigger brush than what we saw in that picture. If stems are under 2" in diam for sure it will chop it up, which is about 3 times the apparent diam of the brush shown. (Maybe there are bigger stems that we are not seeing ?)
Not to diminish your effort or your picture, but that looked like an relatively easy task for the rotary brush cutter. /forums/images/graemlins/wink.gif
