Deere 350 trackloader hydro quit working

[tanda]

I have a john deere 350 track loader. Think its either a 74 or 76 model. I was grubbing around a stump today and the loader just quit! I heard a noise somewhere near the front which sounded like a hose blew. there is no fluid that I can see anywhere, but once I idled down I can hear a rattleing noise that sounds similar to a bad bearing. the hydro fluid is low (which I didnt realise until after the fact!) but everything was working fine prior to all this. Its been a really strong machine!
Any help or ideas would be greatly appreciated!!!!

I'm not an expert at hydraulics "Still learning about them myself" But Could the pump have blown a seal?

Thats kinda what i was thinking but theres no fluid that i can see. im wondering if the shaft snapped. I can see and put my hands on the pump but everything on this loader is so tight you cant get to it!! also i can put two fingers on the shaft and turn it some.... dont think i should be able to do that!!

The snapped shaft could be it. I am too thinking you wouldn't be able to turn it that easy. Because even on my little pump for my backhoe, I have to really have a good grasp on the shaft to turn it.

Even with the pulley attached it still takes a bit of effort to get it to turn.

Or something else could have broke in the pump. A gear etc.

Hopefully someone with more knowledge will chime in.

Hope you get it figured out.
