I drained the hydraulic fluid and replaced it with AW46.

When I lift the front blade, the valve chatter is less than before. And the pressure gauge is showing about 800 psi instead of about 600 bedore. The blade seems to move upward a little faster than before.

Maybe also related, I also now have down force on the blade. Previously, I could get the blade to settle back to the ground but it wouldn't apply any downforce. Now I can lift the front of the tractor if I apply downforce on the front blade.

you should have more than enough down force to lift the front of the crawler off the ground ..
