After running my bush hog for 15 to 20 minutes the tractor pto and lift stop. Fluid is full and no leaks that I can see.
Any suggestions
 
Hello Msmith welcome to YT! Not familiar with those
tractors or really Fords in general. A common first
thing to do is change fluid and the filter. I am not sure
what type of hydraulic filter it has or where it is
located. I am just going to make a broad statement
about your symptoms. I see your tractor has wet
brakes. I do not know if your tractor model can suffer
from this problem, but in some brands and models the
brake lining can delaminate from the brake disc or
pads. As it peels away it finds its way into the suction
screen for the pump. Eventually enough builds up that
it plugs it enough to stop flow or severely restrict.
Then after it has been stopped a while the crud falls
off the screen and when you restart it works again for
a while. Might try draining a gallon of two of the fluid
out into a clean pan. Then see what might be in it. Not
sure if you will get a better response on the Ford topic
section or not. I am adding a link to it.

Filter is the large cannister below the left hand foot rest. How long since you changed fluid and filter? Is the hyd fluid clean or dirty?
 
Just recently replaced oil and filter. If I kill the tractor and let it set for a few minutes it goes back to working for another 15 minutes or so and this can be repeated all day. I thought I had something sucking against the pickup tube but the tractor has been cleaned thoroughly. Nothing blocking it
