Hello there. I was looking into purchasing a brush cutter to handle a bunch of pretty dense overgrowth both on the side of my house and in my backyard; figure about 1/4 acre of total brush. Some of these plants are more than 6 feet high. Said brush consists of a LOT of woody stems (think overgrown forsythia), green, pulpy stems (think blackberry bushes), and some other general mis-mash. The largest diameter stem/sapling is probably about 2" in diamter. There is this brush cutter for sale in NJ, not too far from me that I was thinking of buying:

I've heard speak that Gravelys are "tanks" and are excellent machines. My question is will this machine do the job, or is it meant more for just high grass? I've seen simplicitys, DR brush cutters, and Billy Goat machinery that seems to chop the stuff I mentioned above with ease. Will this do the same job, or am I wasting my time/money? Thanks!
