1. ) A manual electro-hydraulic selective depth control system for establishing a set position of a device above the ground as the device is moved across a surface, the selective depth control system comprising:

  • a. a toggle input device for specifying a plurality of position settings;

    b. a device position sensor for determining a measured device position; and

    c. a hydraulic position control system having a programmable ground zero position and a programmable maximum depth position for the device, the hydraulic position control system maintains the current position corresponding to the measured device position within a specified position within a specified position window around a set position programmed relative to the ground-zero and maximum-depth position;

    d. wherein the toggle input device comprises;

    e. a working position that places the set position at a programmed position;

    f. a shallow position that places the set position at a minimum deployed depth;

    g. a zero position that places the remote solenoid in a permanent de-energized mode
