Power down on a disc would allow for the cylinder to lower the disc to the point where the disc is in the ground, and holding the valve further would raise the wheels off the ground, raising the wheels and adding their weight, allowing for further penetration of the disc into the ground. ie: single spool remote valve has one hose, double spool remote has two hoses.
