Yeah, only 35#. I've only used a 15# before. I can only imagine what a pneumatic feels like. I'll worry about that when the driveway starts to fall apart.
Way better than a sledgehammer though.
I think when the driveway gives, you should think about something like a bobcat with the attachment to bust up the concrete. Then just flip around and use the bucket to load the pieces into a dump truck?
Was it an electric 35#?? If so, those things really are nothing. I grew up around a 105# Thor air hammer hooked to a tow-behind air compressor. That thing would kick your azz after a few hours............
Like jomama said,you could call yourself a man after spending a day on one of those,here is something similar at 90#
