Strike at Harvester Ends

International Harvester Co. and the United Auto Workers union reached a tentative contract agreement, ending a walkout by more than 11,000 workers that had begun less than 48 hours before, a company spokesman said in Chicago. Workers were to return to the job immediately, Harvester spokesman Bill Greenhill said in a statement announcing the proposed three-year contract. He said no further details were available on the pact. The strike began at midnight Friday, with the union saying it was seeking restoration of benefits it conceded to the ailing farm equipment giant in 1982.
