Abstract
An agricultural machine includes a main frame, a rockshaft pivotably coupled to the main frame, a lift actuator couple between the rock shaft and the main frame, a lift arm pivotably coupled to the main frame below the rockshaft, a lift strap coupled between the rockshaft and the lift arm, and a lift actuator coupled between the main frame and the lift strap to pull the lift arm upwards. The agricultural machine includes header, which is supported by the lift arm and the float actuator above the ground at a desired harvesting height. During harvesting, the lift arm may encounter uneven ground, causing the header to move away from the desired harvesting height. By measuring float actuator pressure or header position and by changing the pressure in the float actuator or lift actuator in response, the header can be rapidly returned to the desired harvesting height.
