A lifting mechanism for moving a trough from a lowered position to an elevated having a pair of guide tracks operably coupled to a trough cradle by a pair of roller mechanisms. A lifting arm operably couples the trough cradle to a drive mechanism. As the trough cradle is elevated, the roller mechanisms move away from the drive mechanism and the trough cradle to rotate about a transverse axis.
