<p>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....<br>

<div style="font-family: arial, helvetica, sans-serif; color:

If this is caused by the relief valve sticking or leaking, can
I access and replace it through the RIGHT access panel?</div>

Thanks for any advice,</div>
