Pros and Cons of the John Deere Combine Harvester

As with any machine, there are pros and cons to consider when making a big purchasing decision. Here are some main factors of the S series.

Benefits

  • CommandTouch multi-speed feederhouse drive—this feature allows users to harvest crops faster and match ground speed to crop conditions.
  • High-performance cleaning system—the multi-levelled shoe design reduces slop sensitivity and delivers results.
  • ProDrive system—valuable harvest time is not lost shifting on uneven terrain. This system automatically shifts between two speed ranges as the ground changes for higher productivity.
  • Power folding grain tank extensions & covers—close the grain tank at the touch of a button with CommandCenter technology. This is designed for use of ease for height-restricted areas.
  • Flexible cab options—the S Series cab options provide high visibility and operator comfort.

Things to Consider

  • Expensive to buy—depending on the model you choose the S Series can be expensive to buy, especially brand new S700 models. Used John Deere combine harvesters range from $85,000 to $500,000 depending on the series model.
  • Maintenance—as technology advances so does the maintenance required. If problems occur you’ll need a technician to diagnose the issue and re-calibrate the machine. This could mean downtime and lost productivity.
  • High fuel consumption—some users have noted high fuel consumption is an issue with the S Series but it’s not clear under what circumstances this occurred.
  • Grain loss—according to anecdotal feedback, early S Series models delivered a higher grain loss. However, with new technology integrated into the latest S600 and S700 machines, some say this problem is resolved.
