1996 963b track loader blew trans hose replaced and not have no bucket function at al

I had a hose wear and leak it was the transmision I assume as when I noticed the leak the Hydrostatic oil was low. on the drivers side below the floor there is a bell housing that the HS filters are in, behind it at the base there is a 1 inch or bigger hose that goes to the back of the passenger side left just below the fuel pump its a pump the size of an old car starter. I had to jack the cab up to replace it and when finished I started it I had no bucket controls at all nothing. I thought the bucket ran on a seperate system? as the oil tank is in the front or I may have pinched a hose when I let the cab down but they are very neatly run and the cab tilted to front and it does not look like I did pinch it. My question is could I have some how lost the prime when I replaced the hose maybe the controls run on hydrostatic and there is air and it needs to bleed the air out. My thought is the controls for the bucket may run of the trans oil maybe?? help
