I've got a 322 that I believe blew a hose and pissed out all the hydraulic fluid. I'm pretty sure it was a drive hose since I had something similar happen earlier this summer. Problem is I can't lift the cab due to the machine is in a bit of a hole and i can't get the arms all the way down. So I dumped a pail of hydraulic fluid in, started it up but the hydraulics will not work at all, not even a little bit, not even a sound of them trying absolutely nothing. Any ideas?
