Available for the 2018 season, the all-new John Deere V400 Series variable chamber round balers will replace the existing 800 and 900 models. Completely re-styled, key features include a stronger, heavy-duty duty welded frame, a larger diameter pick-up and a one-piece in-line auger rotor for improved intake and crop flow. Other developments include bigger drive chains, oversize roller bearings, a new bale density tension system and Hardox steel rotor tines.
