Automatic grading electronic controller

Abstract

A skid steer control box used with a dozer blade attachment and laser control system that integrates the laser controller and native skid steer controller as they affect a selected solenoid related to a hydraulic valve.

What is claimed is: 
     
         1 . An electronic controller for controlling a skid steer vehicle having an automatic grading control system comprising:
 a skid steer vehicle with a manual electronic control configured to allow an operator to manually control the skid steer vehicle with a joystick;   the manual electronic control is electronically connected to the electronic controller through a first relay;   the automatic grading control system is electronically connected to the electronic controller through a second relay;   the first relay and second relay are electronically connected to a solenoid/servo that effects a movement of an implement attached to the skid steer vehicle;   the first relay is biased to isolate the manual electronic control from the solenoid/servo and the second relay is biased to connect the automatic grading control system to the solenoid/servo when there is no signal from the manual electronic control;   when a signal from the manual electronic control is received by the first relay the first relay electronically connects the manual electronic control to the solenoid/servo and simultaneously the second relay isolates the automatic grading control system from the solenoid/servo.   
     
     
         2 . The electronic controller in  claim 1  further characterized in that when the manual electronic control is isolated from the solenoid/servo any signal from the automatic grading control system is first sent to a comparator causing the comparator to send a conditioned power from a source other than directly from the automatic grading control system to the solenoid/servo. 
     
     
         3 . An electronic controller for controlling a skid steer vehicle having an automatic grading control system comprising:
 a skid steer vehicle with a manual electronic control configured to allow an operator to manually control the skid steer vehicle with a joystick;   the manual electronic control is electronically connected to the electronic controller through a relay;   the automatic grading control system is electronically connected to the electronic controller through the relay;   the relay is electronically connected to a solenoid/servo that effects a movement of an implement attached to the skid steer vehicle;   the relay is biased to isolate the manual electronic control from the solenoid/servo and the relay is biased to connect the automatic grading control system to the solenoid/servo when there is no signal from the manual electronic control;   when a signal from the manual electronic control is received by the relay the relay electronically connects the manual electronic control to the solenoid/servo and simultaneously the relay isolates the automatic grading control system from the solenoid/servo.   
     
     
         4 . The electronic controller in  claim 3  further characterized in that when the manual electronic control is isolated from the solenoid/servo any signal from the automatic grading control system is first sent to a comparator causing the comparator to send a conditioned power from a source other than directly from the automatic grading control system to the solenoid/servo.
