[AT] Ferguson TO20 weak hydraulics

[Cecil Bearden]

Years ago when I worked on at least 2 massey hydraulic lifts a week, the 
relief valve very rarely was the problem.  It was the easiest to 
replace, but very few times solved the problem.  If it has been popping 
off a lot, then it might be the problem.  If it could have been rusty 
and then popped off a few times it might have a broken spring.    It is 
accessed from the PTO shifter side as I remember.  You can take off a 
side cover plate and try to lift the blade while running and watch for 
oil dripping from t he top or spraying from the bottom.   The top would 
be the lift cylinder.  You do not specify how the loader is connected, 
but if it is plumbed into the tractor hydraulics, the loader supply has 
to be shut off for the lift to work....
