Once I remove the bars across the top I flip them upside down and then use the forks of the tractor to lift the cage. On some the bladder slides right out but on others I need to shake it pretty hard on the forks but they do come right out.
So they were just wedged in there a bit. Took a track bar with me, flipped them on their side and used the bar to pry them our. Didn't take much at all once I got them started.
All the totes I have the black plastic was just at the corners. Once the bladder was out they just fell out
