Abstract
A row following apparatus that attaches to the forward portion of the frame of a tractor towed harvester or cultivator which operates to monitor and adjust the position of the harverster. The row following apparatus uses a pair of pivotally attached sensing feet for following the crop rows. These sensing feet are attached to the frame of the present invention by a pair of automotive style ball joints. The use of the ball joints allows the pivotal movement of the sensing feet in a 360 degree manor that is unattainable with other methods of attachment.

An automatic row crop implement positioner for use on an implement having a tongue hitch pivotally mounted in a horizontal plane to a primary frame which is pivotally mounted in a vertical plane to a pivot frame, said automatic row crop implement positioner comprising:
- an implement positioner frame mounted to a said pivot frame;
- a left and right foot ball joint mounted to said implement positioner frame;
- a left and right elongate positioner apparatus foot each of said left and right feet having a forward and rearward end, said forward end being mounted to said left and right foot ball joint such that said left and right foot may pivot about said foot ball joint in both a horizontal and vertical plane;
- a means of detecting vertical movement of said left and right feet and a means of imparting vertical movement to said main pivot frame so as to move said main pivot frame in a vertical plane;
- and
- a means of detecting horizontal movement of said left and right feet and a means of imparting horizontal movement to said main pivot frame so as to move said main pivot frame in a horizontal plane.
An automatic row crop implement positioner for use on an implement having a tongue hitch pivotally mounted in a horizontal plane to a primary frame which is pivotally mounted in a vertical plane to a pivot frame, said automatic row crop implement positioner comprising:
- an implement positioner frame mounted to a said pivot frame;
- a left and right foot ball joint mounted to said implement positioner frame each of said foot ball joints having a ball and socket type fitting;
- a left and right elongate positioner apparatus foot each of said left and right feet having a forward and rearward end and a mid section, said forward end being mounted to said left and right foot ball joint such that said left and right foot may pivot about said foot ball joint in both a horizontal and vertical plane;
- a first and second open spring at said forward ends of said left and right elongate positioner apparatus foot so as to bias said forward ends inward toward each other;
- a first and second close spring at said mid sections of said left and right elongate positioner apparatus foot so as to bias said mid sections inward toward each other;
- a means of detecting vertical movement of said left and right feet and a means of imparting vertical movement to said main pivot frame so as to move said main pivot frame in a vertical plane;
- and
- a means of detecting horizontal movement of said left and right feet and a means of imparting horizontal movement to said main pivot frame so as to move said main pivot frame in a horizontal plane.
An automatic row crop implement positioner for use on an implement having a tongue hitch pivotally mounted in a horizontal plane to a primary frame which is pivotally mounted in a vertical plane to a pivot frame, said automatic row crop implement positioner comprising:
- an implement positioner frame mounted to a said pivot frame;
- a left and right foot ball joint mounted to said implement positioner frame each of said foot ball joints having a ball and socket type fitting;
- a left and right elongate positioner apparatus foot each of said left and right feet having a forward and rearward end and a mid section, said forward end being mounted to said left and right foot ball joint such that said left and right foot may pivot about said foot ball joint in both a horizontal and vertical plane;
- a first and second open spring at said forward ends of said left and right elongate positioner apparatus foot so as to bias said forward ends inward toward each other;
- a first and second close spring at said mid sections of said left and right elongate positioner apparatus foot so as to bias said mid sections inward toward each other;
- a vertical sensing valve for detecting vertical movement of said left and right feet and a vertical adjustment cylinder pivotally attached between said pivot frame and said primary frame for imparting vertical movement to said main pivot frame so as to move said main pivot frame in a vertical plane;
- and
- a horizontal sensing valve for detecting vertical movement of said left and right feet and a hydraulic cylinder pivotally mounted to said tongue hitch and said primary frame for imparting horizontal movement to said main pivot frame so as to move said main pivot frame in a horizontal plane.
