Textron Specialized Vehicles will add from 100-150 jobs to its Augusta workforce during the next year as it combines operations with Jacobsen, of Charlotte, N.C., a leading manufacturer of turf-care equipment under the Jacobsen, Dixie Chopper and Ransomes brands. Those new jobs will come in addition to an expansion announced earlier this year, which will create about 400 new jobs over the next five years, said Brandon Haddock, the director of communications for Textron Specialized Vehicles.
