Pressure to hold or raise the head for a work implement

A method of controlling an agricultural machine, the method comprising:

• providing an agricultural machine having a frame, an implement linkage system attached to the frame and configured for attaching a selected work implement from a plurality of different work implements to the frame, wherein the implement linkage system includes a left connecting arm and a right connecting arm, a left float cylinder attached to and interconnected with the frame and the left connecting arm, a right float cylinder attached to and interconnected with the frame and the right connecting arm, wherein the implement linkage system is controllable in a float operating condition allowing the selected work implement to vertically track a ground surface during horizontal movement over the ground surface, a controller including a processor and a memory having a float control algorithm stored thereon;
• identifying via the controller the selected work implement from the plurality of different work implements;
• soliciting a desired operating condition from a plurality of predefined settings from the operator via an input operable to receive instructions from the operator, wherein the desired operating condition corresponds to a designated pressure setting of the left and right float cylinders in a database;
• operating the work implement in a float mode of operation;
• commanding the work implement to a raised position;
• automatically determining via the controller a maximum pressure and a position that the maximum pressure corresponds to for each of the left and right float cylinders;
• and
• automatically modifying, via the controller, the designated pressure setting of the left and right float cylinders in the database based on the maximum pressure and position for each of the left and right float cylinders.
