It also would be a fix for a broken cylinder in the top deck. However
if you try it hold the lift arms down with the drawbar stay bars and
then use the external outlet for a single acting ram, it will bend the
stay bars. They are only to be used in tension.
We used to install a diverter valve on the top deck of the masseys to
run an external control valve. We would dump the oil back into the top
deck through a port in the top deck. To use the external valve, the
lift arms were raised to the top, then dropped about an inch, then the
diverter valve was opened and the quadrant control lever raised to the
top and the pump then ran oil to the external valve.
