Abstract
Systems and methods for implementing a machine control system in a construction machine having an implement with an extender. The machine control system may include an acceleration sensor mounted to the implement and a processor configured to perform various operations. The operations may include determining that the extender is not moving and in response operating under a first control scheme. Operating under the first control scheme may include receiving acceleration data from the acceleration sensor, generating an estimated slope of the implement based on the acceleration data, and modifying a slope of the implement based on the first estimated slope by causing movement of at least one tow arm. The operations may also include determining that the extender is moving and in response operating under a second control scheme. Operating under the second control scheme may include maintaining the slope of the implement substantially constant.
