2013 John Deere s660 Combine. This is a pre def machine!!! In great condition. This machine has Kondex concave!! Say goodbye to high Doc grain, our average went done to .80 in wheat. They make it very easy to change out for different crops. Plus it lets this smaller machine harvest faster, 5mph in 55bu/ac wheat. We have also added a 150bu hopper extender, so now it has 400bu capacity hopper! Call for all the info. This is the perfect combine for getting some acs done and saving on FUEL COST!!!
