Abstract

In an exemplary embodiment of the present disclosure, a payload determination method associated with a machine includes determining first head-end and first rod-end pressures of a first actuator operably connected to a boom of the machine as the boom is raised across a position at a reference lift angle. The method further includes determining first head-end and first rod-end pressures of a second actuator operably connected to a work tool of the machine as the boom is raised across the position. The method further includes determining a weight of a payload carried by the work tool based on the first head-end pressure of the first actuator, the first rod-end pressure of the first actuator, the first head-end pressure of the second actuator, the first rod-end pressure of the second actuator, and a determined pitch angle of the machine. In such an exemplary method, the payload is carried by the work tool during at least one of the determining steps described above.
