Selective position control system and method
First Claim
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 processor programmed with a ground zero position and a programmed maximum depth position for the device, wherein the hydraulic position control system maintains a set position corresponding to the measured device position within a specified position within a specified position window around the 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 one of said programmed positions;
f. a shallow position that places the set position at a minimum deployed depth;
g. a zero position that places the hydraulic position control system in a permanent de-energized mode.

Abstract
A selective position control system and method are disclosed. The system includes a processor, remote control and solenoid valve in conjunction with interacting valving, a potentiometer or ultra-sonic device and necessary wiring. The system interfaces wit the tractor'"'"'s manual hydraulic lever operations which raise or lower equipment by effecting cylinder extensions or retractions. The system is separate from the tractor hydraulic system but interfaces by energizing a solenoid valve that stops oil flow and causes the manually detented tractor hydraulic valve to center from a working position. The system'"'"'s processor establishes two programmed toggle switch settings; one typically slaved to the other. The system accommodates other manually activated positions, up or down, from the programmed positions, with return to set points of programmed positions. The remote control incorporates a toggle device with three positions, an up/down rocker switch, a set switch and an LED readout.
