[QUOTE="MNBobcat, post: 30116, member: 3234"] Hi Everyone, I could use some advice. Tomorrow I'm renting a concrete breaker for my 763 Bobcat. The concrete I have to break up is a solid 3 foot wide by 3 foot wide block that extends 2 feet above grade and goes down into the ground 5 feet. I only need to break up the block to a depth of 6 inches below grade. Whats left after that can stay in the ground. I've never used a breaker. What would be the best approach? Should I try and enter the block horizontally low to the ground and break the top off and then work my way down or should I start at the top (vertically) on top of the block and break my way down? I don't know what is faster or if trying to go horizontally is not even practical. If you start working in a straight line, top down, can you get a crack going usually? I'm not sure what to expect with something this thick. Also, there is some rebar in it. When I encounter rebar, am I going to need to use a cut-off tool to cut it or can I set the breaker bit on it and break it that way? Right now I have my steel tracks on the machine. I don't need them on the machine any more. Before I take them off, would there be any benefit to having the tracks on for tomorrow or should I just go ahead and remove them today?
