A large round baler is equipped with a chassis, including an outer pair of fixed side walls, that extend rearwardly beyond a pair of inner side walls which form opposite sides of a baling chamber. A deck is supported by a frame with a linkage for raising and lowering the deck with rest to the green. The sidewall is thinner than each of the ends. The isolated metallization is provided in an outmost one of the sub-regions, the outmost one being surrounded by the loop interconnection and corresponding ones of the lattice interconnections.
