Breaking concrete?

My 50 year old concrete stoop is in bad shape. It's 3' high and 48" square at the top. Today I sunk a 7" long masonry bit into it in several places and found nothing but concrete. I'm thinking it might be solid through and through. I need to bust this thing up and get it out of here, along with a 15'x20' concrete slab that is 3-4" thick.

Ideally this might be a good job for a large air compressor and full-sized pneumatic jackhammer. I'm wondering what my other options are? Is an electric jackhammer up to the task? How about a bobcat with a breaker attachment?

The local rental place has all the above options, I'm just not sure which is the most painless and cost-efficient?

Opinions?

You seem like a bobcat with breaker attachment gal to me.

concrete

The Bobcat will be more kidney friendly, and faster, but might cost a lot more. The electric breaker will take forever if it is actually all concrete.

I have a 3 function hammer-drill that is invaluable for small concrete breaking and hole drilling, but this sound like a job for super breaker. A number of years ago I had to remove concrete steps, and I rented a big jack hammer and compressor. I was overpowered. I ended up hiring a guy with a backhoe and dump truck. He just pulled and rolled the whole thing to the street and into the truck! It gave real meaning to the expression, "Cast in concrete".

I'd go with the bobcat. The jackhammer will certainly do the job but then you have to deal with moving the concrete to your disposal area/dumpster/neighbors pickup.

I have personally spent a lot of quality time with a Hitachi 70lb demo hammer. It'll get the job done (eventually) and maybe do you in as well, but you can't hang a bucket off of it to move and load the debris when your done.

If the stoop is solid, you could always try some non explosive demolition agent

Another vote for the bobcat.
