re: Jackhammering a small concrete pad

It’s all about the slab thickness and if there is metal in there. The absolute worst is firing up the jackhammer and it penetrating the slab in the first 5 seconds in every punch. Lifting the hammer out with a long bit that’s stuck will wear even the strongest guy out in :30min.
Renting a mini bobcat (t450 or something similar) is your answer. Get the forks under the slab and work it.

Anybody tried one of those Vevor jackhammer for under $100? I know they are probably cheap but they might be good for a small.project

You can rent a towable air compressor and Jackhammer. They do a great job. Or a person with a jackhammer and bobcat.
My nephew has a Dingo, it has a jackhammer attachment. He also has my dump trailer.

relatively easy for someone strong and mechanically inclined?
Is 1 day enough for the rental?
Those are great for removing old tile and glue down wood floors. Some come with a wide blade.

Man it broke the concrete just fine. The problem was after holding it and moving it for two hours my back was seized up. It was a plug in unit, somewhere around 100lbs.
Alternately, I brake my grandmother's entire back porch into 18in squares with two sledge hammers in under an hour

Try Dexpan. I've used it numerous times with great results. Drill the holes and pour it in, then wait. Save your back.

It's two different sections. One looks perfect and the other has cracked due to some sinking.
The section that is cracked has no reinforcement and will be easy to get out. 30 minutes.
The section that looks perfect has reinforcement and will take the rest of the day and will be in small pieces.
Please come back and let me know how my assessment fared out.

I actually took a few easy swings with the sledge hammer last night, just to test it out. Got a break all the way through, not sure if I'd want to be doing that all day though. I definitely think I'd need a jackhammer for the stair section.
The concrete is 3". I don't think either side is reinforced, The side in good condition just stayed level and didn't sink like the broken one did.
Gonna consider this too, thanks for all the feedback. I'll try to remember to follow up with how it goes.

Not sure yet, I saw a company off the interstate the other day that said they do concrete recycling. But I haven't contacted them yet.
Do you know anyone with a camp on the water? I have friends that have a camp on Hwy. 90 outside N.O. city limits heading east and they will gladly take "rip-rap" aka broken up concrete, oyster shells, etc. to use as a breakwater on the water's edge to help with erosion.

I live in Utah. Maybe I could just dump it in the Great Salt Lake

You need to figure out disposal first. Because it can be literally 50% or more of the cost for someone that doesn't have options.
As said, breaking up the concrete is one thing. Then you have to rip it up, carry it to a truck or trailer, take the truck/ trailer somewhere, then dispose of it which includes unloading and moving it again.
I'm not all for hiring someone, but sometimes its literally cheaper to hire someone than renting equipment and disposal.

Hell, ammo for pelting Mormon Missionary's when they go knocking on doors---------------just a thought..

Yeah I'm renting a mini ex or even a dingo skid steer for that. Concrete is heavy, breaking it up is just the first part of it.

Are these pre-made stairs or poured in place? You can definitely smash pre-made with a sledge but it will have wire in it.

A Harbor Freight hammer drill...the big one...would help. Drill some holes in a line and whack it with the sledge. It'll break along the holes...usually. I've used that drill a surprising amount over the years.
