#$%^&*AU2006201954B220120223.pdf#####HEADER HYDRAULIC FLOAT SYSTEM Abstract of the Disclosure In an agricultural combine, a header float system using a floating header having a frame, a support member supporting the frame from the ground, and a suspension variably supporting the frame from the combine. The suspension comprises a subframe removable attaching to the combine, links movably attaching the frame and the sub-frame, and one or more float cylinders moveably supporting the frame from the sub-frame. A float circuit connects to the float cylinder, and a float valve connects the float circuit to a main hydraulic circuit. A pressure sensor connects to the float circuit, and a controller communicates with the float valve and the pressure sensor. The controller maintains pressure in the float circuit at a target value by continuously reading the pressure sensor and commanding the float valve to add or subtract hydraulic fluid in the float circuit until pressure equals the target value.3/10 0%0. i~czz O O
