A control system for a machine may include a chassis an implement attached to the chassis, a first sensor, a second sensor, and a controller in communication with the first and second sensors. The first sensor may be configured to generate a first signal indicative of an angle of the implement with respect to the chassis. The second sensor may be configured to generate a second signal indicative of an angle of the chassis with respect to gravity. The controller may be configured to determine an implement mainfall angle based on the first signal and the second signal; process the second signal using a low pass filter to determine a filtered chassis pitch angle; determine a target mainfall angle based on the first signal and the filtered chassis pitch angle; and generate a command signal based the target mainfall angle and the implement mainfall angle.
