John Deere 510C backhoe

I have been wrestling with a backhoe that is on my property that actually belongs to a fellow down the street. I get to use it when it's operating, but lately that's not been often. I had starter problems and eventually
had to place a second solenoid on it to get it to start. Had to put a tube in the front wheel and thought after that I could use it to dig out a stump. But I went to move the boom and it sprung a hydraulic hose. Now
this hose runs from the control to inside the lower part of the backhoe boom. The crowd cylinder, which is inside the boom, is right in front of the top connection of the hose so I can't get a wrench in there to get it
off. By the way, I haven't gotten to where I am ready to remove it. The other end of the hose is accessible. I am hoping that if I take off the fitting I can get to, I might be lucky enough to turn the hose to get it off,
but I am not counting on it. Does this mean I have to at least remove the crowd cylinder. The boom weighs about 1 ton I think. To me it doesn't seem very well engineered for maintenance, but it is what it is.

Those boom lines are Nasty to change out,,no way of really explaining how to do it,,your just gonna have to wrestle with it till you get it...

I have worked on different parts of 3 brands of backhoe, wonder why they try to make regular wear items so hard to get to, job security for industrial mechanics?
