"why couldn't the ford manual said that ?"
Because it's not what it actually does ;-)
1) Position control is real simple. In position control mode the 3pt lever sets the height of the lift arms and the control mechanism maintains that height across varying terrain. Used primarily for things like mowers.
2) Draft control is more subtle. In draft control mode the 3pt lever sets the initial depth of the plow/implement as it is being pulled through the ground. However, when the plow/implement encounters heavy soil conditions that increase the pulling resistance and would cause the tractor to loose traction the draft control mechanism raises the implement just enough to keep a constant "draft" or pulling resistance on the tractor. When the plow passes through the heavy soil and back into lighter soil it restores the originally set depth. As you might guess when you hit even lighter soil the plow will run deeper than the preset depth.
