We have removed a # of concrete decks from pool surroundings to driveway entrances. I have always used a skidsteer with forks and a mini x with thumb. I cut the lines first with a quick cut to score it and its removed with minimal time and mess. If the concrete is over 6" then I agree a jackhammer may be better suited. Side note, we all have our preferred methods which usually means whatever we own we try to use first. If we are renting a machine its the logical choice to use a jackhammer att. on a mini x.
