Deere & Co. disclosed Tuesday that it intends to shutter its 800-worker manufacturing facility in Welland, Ontario, and to transfer the Canadian plant's production to existing Deere factories in Wisconsin and Mexico. The Moline maker of agricultural equipment said the closure will generate after-tax charges of about $90 million, with roughly half of that amount coming in Deere's fiscal fourth quarter. Shutdown of the Welland plant, which makes "Gator" brand utility vehicles and other equipment, will be completed by the end of 2009. The Canadian plant's utility-vehicle production will be shifted to Deere's plant in Horicon, Wisc., Deere said; its production of cutting and loading attachments will go to existing Deere plants in Monterrey and Saltillo, Mexico.
