This cost about as much as two days hire! I've taken down a couple of brick and reinforced concrete gate post - I reckon each one weighs about half a tonne or so. I've also broken some quite think ground concrete, up to about six inches thick.Breaking the gate posts was hard work as it's mostly horizontal use of the hammer (which weighs about 15 kg), but breaking the ground concrete simply meant holding the hammer in position and letting its own weight do most of the work.Recommended, especially for the price.
