check if not one of the hoses from the loder to the loader valve has worked lose one of the quick fittings, also are you shure the cables to the valve are working. can you hear the tractor work when you operate the loader joystic ?

how is hydrulic lines conectet to tractor? are they coected to pump direktly or at the eksternal copling att the rearend? iff coected to eksternal coplings you need to operate tath valve
when you want to operate the fel

if your tractor has a valve chest being fed from the back of the tractor,with a return in coupling 0,and the feed in coupling 1.bring the lever for hydraulics all the way back and hold it in that position by means of the fixing knob,this will send oil to your valve chest.
