Leaking hoses on JD 440 loader

[barngal]

I have leaks from 2 hydraulic hoses on my JD 440 loader. I/m hoping its just the hoses, but worried it could be something else.
The leaks are squirting and seeping thru the hoses. The hose on the left (head-end bucket cylinder) squirts out; the hose on the right (rod-end lift cylinder) leaks, but not as much pressure. There are no leaks from hose fittings, or anywhere else that I can see. The bucket functions normally.
The tractor is not not stored under a cover, so I guess it could be sun damage, but I'm concerned that something else may be going on, since 2 hoses have these symptoms, not just one.
Should I just replace the hoses? (I'll replace them all) or ? I replaced all the rest of the loader hoses just a few years ago; these 4 are the only ones I haven't done yet.

Replace the ones that are currently leaking. You had a reason to replace the others; were they leaking then?

Yes, a hose on the front of the loader sprung a leak, so I replaced everything except the 4 main ones. The main ones looked newer, the ones on the front were all original. Just figured they were old and sunbaked so do 'em all.
I'm replacing these 4 that are the supply/return lines, since 2 are leaking and a 3rd one has some big cracks at the bottom, figure they are due. My only concern was if there was something else that was causing the 2 top hoses to leak; didn't want to pay for new ones and then have them ruined too. But I'm on my way to Napa to get them. Sorry I couldn't post the pics yet, will do it later if its will help.

How old is the tractor? How many hours on it? Does it sit out in the scorching sun/rain/ozone? You could coat the hoses with sunscreen!:laughing:
Yes to pics.
