I use TnT. My TnT does not have pilot lock valves. With a constant load the cylinders will eventually drift.
For the top link, I remove the cylinder and attach the solid top link if I'm pulling/carrying heavy loads using the top bar of my QH.
For the side link, I remove the cylinder and attach the solid side link when I'm using my mounted brush cutter so everything stays level.
My uses and equipment is scattered between two farms. Nothing more aggravating than needing to change links and one required being at the other location.....
Thanks for asking.
