This tube allowed the oil to enter the bottom of the cylinder always had the large stage move out first followed by 2cd then small stage. Now if some of you out there want a double acting 2 to ? cylinder I can supply the information, there is a trick to it, but it sure makes the dump box come down faster.

I'm intrigued Earl. Our Euclid has a 3 stage cylinder and it powers down because the box tips past center. I would like to know how it works.
