1. A system for calibrating a header flotation system of an agricultural vehicle having a header, the header flotation system configured to manage a downforce of the header against the ground, the system comprising:

  • a controller configured to a) monitor the position of the header as the header is propelled across the ground and floats in a flotation mode, b) determine an acceleration value of the header as it moves between two positions while in the flotation mode, c) calculate a change in the header weight based on the acceleration value, and d) calibrate the header flotation system by calculating a revised upforce signal configured to maintain constant a predetermined downforce of the header against the ground based upon the change in the calculated weight of the header while in the flotation mode.
