System for machine and dual implement control

A system for controlling the lateral traverse position of a front three-point hitch mounted side-shifting implement and a rear three-point hitch mounted side-shifting implement on a mobile machinery such as an agricultural tractor, while simultaneously assisting the tractor operator of controlling the position of the tractor relative to the positions of each of the two side-shifting implements, the system comprising:

• a) a controller configured to use information from a position monitoring system to control and position the front mounted side-shifting-implement to track a predetermined path, and the controller configured to use information from the position monitoring system to control and position the rear mounted side-shifting-implement to track a predetermined path;
• b) a rear rover data receiver mounted on the rear side-shifting-implement to enable the position monitoring system and the controller to control the position of the rear side-shifting-implement, and a front rover data receiver mounted on the front side-shifting-implement to enable the position monitoring system and the controller to control the position of the front side-shifting-implement;
• c) a first rear sensor mounted on the tractor or mounted in a position representing the tractor position, a second rear sensor mounted on the rear side-shifting implement or mounted in a position representing the rear side-shifting implement position, and the first rear sensor and the second rear sensor sensing a relative position relationship with each other and relaying information to the controller;
• d) a first front sensor mounted on the tractor or mounted in a position representing the tractor position, a second front sensor mounted on the front side-shifting implement or mounted in a position representing the front side-shifting implement position, and the first front sensor and the second front sensor sensing a relative position relationship with each other and relaying information to the controller;
• and
• e) the controller enabled to receive sensor relationship data from the first and the second rear sensors to determine and display the data on a sensor display screen showing the position of the tractor position relative to the rear side-shifting implement position, and the controller enabled to receive sensor relationship data from the first and the second front sensors to determine and display the data on a sensor display screen showing the position of the tractor position relative to the front side-shifting implement position, therefore assisting the tractor operator in determining the required or preferred steering of the tractor.
