After you invest in a new or used piece of equipment from John Deere, it’s critical to put in the work to maintain it over time. Maintaining John Deere combine parts, for instance, is essential to keep everything in working order over time. That being said, there are several steps you need to take in order to keep your combine parts operating like new.

Let’s take a look at the steps for maintaining John Deere combine parts.

  • The two main areas you’ll want to check on your combine before harvest are the elevator chains and augers.
  • John Deere combines have two elevator chains: the clean grain and the tailings. Too much tension is the most common reason for excess wear. Failing to address this can cause shaft failures.
  • To adjust the chains, remove the latch and open the elevator door.
  • Next, remove the nuts from the bearing cover.
  • Use the adjusting nut to loosen or tighten the chain as necessary.
  • Afterward, move the bearing carrier downward to tighten the chain.
  • When the chain loosens up to six millimeters or a quarter of an inch from the sprocket, readjust the chain. One half link may be removed to adjust the chain further. Once this has been removed, it’s time to replace the chain and sprockets.
  • Checking wear on the augers is essential to maximizing efficiency and ensuring the best grain quality. Bent or excessively worn augers can result in leaking grain within the system.
  • If flighting is worn to a sharp edge, this can result in excessive grain damage.
  • Schedule an offseason inspection with your local dealer to address any auger concerns.
  • When it comes to your corn heads, you’ll want to ensure that you choose the right stalk rolls for your specific operation.
  • Intermeshing stalk rolls aggressively process stalks, which is best when harvesting high moisture corn.
  • Opposed stalk rolls process less aggressively, leaving residue larger usually 12 inches or longer. This is best in dry corn conditions.
  • The tensioner and built-in gauge are your indications of when it’s time to replace your gathering chain. When there are no more adjustments that can be made, it’s time to replace your chain.
  • To extend the lifespan of your gathering chain and sprockets, switch them to the opposite side of the row unit.

If you have any questions about the John Deere corn heads or combines, you can contact your local John Deere dealer.
