It meshes with the transmission’s drive gear to transfer engine power to auxiliary equipment like hydraulic pumps. You replace it when gear teeth become worn, pitted, or damaged to restore reliable PTO operation and prevent further transmission wear. The ‘S’ designation identifies a specific gear ratio, so always match the same ratio for proper PTO output speed.
