This is a left-wing perspective but the easiest to find, clear summary I found of the outcome.
The contract ratified on November 17 improves greatly on John Deere's first offer to United Auto Workers members.

The third-to-last bullet is interesting. I think you see more and more that companies and labor negotiate to push off a worse deal on future employees (who do not get a seat at the table when the deal is being struck). For example in the NFL the NFLPA got more concessions when they agreed to the rookie contract scale that dramatically lowered rookie salaries, knowing that no future rookies were current NFLPA members anyway. It looks like Deere tried that approach - ending pensions for future hires, which wouldn't affect current union members - but here the workers pushed back and beat it.
