The S670 is great for farmers operating a small-to-medium sized operation. But it also has a couple of drawbacks that you should consider to make sure this is the right combine for you.

Benefits

  • Smart CommandTouch™ multi-speed feederhouse gives power to harvest crops faster and match conditions.
  • Isochronous engine governor keeps machine speed constant. It reduces engine operating speed and allows for less fuel usage.
  • ProDrive™ propulsion system makes harvesting on rolling ground and slopes easy.

Things To Consider

  • 30% smaller cab than the S680.
  • Manually need to fine-tune your requirements to get greatest yield.

According to the John Deere S670 manual, “Regular cleaning and other routine maintenance procedures reduces the risk of fire, chance of costly downtime, and improves machine performance.”

Here’s a quick list of routine maintenance procedures for the S670 John Deere combine.

Daily Routine Maintenance & Cleaning

“These areas may need more frequent cleaning, even multiple times per day, depending on harvest conditions. Be aware of harvest conditions and adjust your cleaning schedule to ensure proper machine function and to reduce the risk of fire.”
— John Deere S670 Manual

First, use compressed air to clean the combine, starting with areas accessible from the engine deck. Once complete, do a walkaround of the combine to check and clean the following:

  • Rear underside of fuel tank
  • Areas around bearings and bearing guards
  • Fuse center and battery box areas
  • Grain elevator drives
  • Walk areas and mud shields
  • Transmission
  • Rotor areas and rotor drives
  • Residue disposal drives

A few other things to consider:

  • Every 10 hours, check the surge tank coolant level while the engine is cold. Coolant level must be between ‘max cold’ and ‘min cold’ lines.
  • Every 10 hours, grease the rear axle spindle bearings and motor pivots (if working in wet harvest)
  • Clean air conditioning drain hose on both sides of cab.
  • Turn the sheave on the Feeder House Reverser Drive Gearcase so fittings are in the 12 and 2 o’clock positions. For severe conditions, grease fitting in 12 o’clock position with 5-8 pumps every 10 hours (10-15 times every 50 hours in normal conditions) and 2 o’clock position 2-3 pumps (or 5-8 every 50 hours).
