Looked at several ways we could break up the rocky soil we have in TX. Found this on special during the holiday with a percentage off sale. We are simple homeowners on a farm and found this to be easily used by both husband and wife. Like that it comes with the dolly to move it around and keep it stored upright. The dolly also has holders for attachments, which we bought a shovel attachment too in addition to the chisel points it comes with. It is not some lightweight either. It does weigh about sixty plus pounds, but is manageable. If it was lighter I do not think it could do a good job or hold up over time. Chiseled through almost two feet of rock for a distance of thirty feet for a carport foundation with ease. Next task is sending it out to the field powered by generator to dig holes for fence posts.Thought possibly could be hard on hands, but this was not the case. Wear heavy leather gloves and found that the handles absorb the vibrations without fatigue. The hardest part was getting the Brute out of deep holes since it is no lightweight. With two people we were able to hoist it out of the holes. Like that this model runs on electric. We have an air compressor and could run an air jack hammer,but the Brute made it convenient to use by generator where ever we needed to hammer rock. Definitely has paid for itself by avoiding all the hours of back intensive labor breaking rock by hand. Definitely worth the bucks and tool envy of others.
