Deere and the UAW had reached a tentative agreement on October. 1 that required a ratification vote by UAW members at John Deere facilities.
Farm equipment manufacturer Deere and Company says United Auto Workers members have approved a new six-year labor agreement that covers facilities in three states.
Neither Deere nor UAW released more specifics on the deal, saying they had agreed not to make any public comments.
Wearing hoodies and jackets against a stiff cool breeze Sunday, hundreds of workers filed into United Township High School, East Moline, to learn the terms of the contract and place their votes.
John Deere has Iowa plants in Ankeny, Cedar Falls, Dubuque, the Quad Cities, and Ottumwa.
The six-year agreement comes more than a month after negotiations began between the union and Deere.
The new 17-page contract includes the following conditions: an agreement that no plants will close, union workers will get increased paid-time off, pension improvements, 89 paid holidays over the six year contract, and a $3.500 bonus.
