OWATONNA, MN (WNS) - A Caterpillar forest products plant will close next year in southern Minnesota – and some of the work will be moved to its plant in northwest Wisconsin. About 100 employees are expected to be let go, when Caterpillar shuts down its Owatonna Minnesota plant on March first. John Carpenter, the head of Caterpillar’s forest products division, said the shut-down was necessary for the company to become more efficient and productive. Part of Owatonna’s work will be done at Prentice in Price County – and some of it will also move to a facility in LaGrange Georgia. Caterpillar will continue to employ 20 engineers in Owatonna. But it’s not clear where they’ll go, because the firm says it plans to sell its factory there.
