Abstract
A method for determining a load in a working machine including a linkage to be connected to an implement includes determining pressure in a first hydraulic cylinder and pressure in a second hydraulic cylinder arranged to control the linkage and determining at least one link angle between at least two links in the linkage. The method further includes, for a selected linkage bearing, determining at least two perpendicular force components acting on the selected linkage bearing, based on the determined pressure in each of the first and second cylinders and the at least one link angle; and determining a load on the selected linkage bearing as a linear combination of the at least two perpendicular force components using predetermined constants for the linear combination.
