Features may include:

More bushels per hour and more acres per day

You have more acres to harvest, which means starting harvest earlier – and sometimes at moisture higher than 32 percent – to get all your work completed on time. The solution is the CF and CR Corn Heads from John Deere. Available in a wide range of row spacings, these corn heads match the capacity of John Deere combines, letting you harvest up to 7,200 bu (253,721 L) per hour in high-yielding, dry corn. Additionally, you can harvest 65 more acres per day with a 16-row corn head compared to a 12-row corn head at the same ground speed.

  • Cover more acres per hour and put more clean grain in the tank – The larger, 19-in. (48.3-cm) auger with increased torque helps you cover more acres per hour than John Deere’s current 700C Corn Heads. This ensures you can harvest high-yielding or high-moisture corn with ease. What’s more, you can reduce the pinching of kernels since the auger has a smaller and more consistent gap between the auger flighting and floor compared to the Geringhoff Rota Disc® system.
  • Relax and enjoy worry-free, automated, on-the-go unloading – The massive capacity boost of an X Series Combine with a 16-row corn head means you’ll need to unload more often. Take the worry out of on-the-go unloading by choosing Machine Sync, which allows the combine operator to control the tractor and grain cart's movement to make unloading more comfortable than ever.
  • AutoTrac™ Row Sense™ is the perfect choice whether you harvest six or 18 rows at a time –To get harvest done on time, you need to run faster, which will make you appreciate AutoTrac Row Sense. Corn heads offer AutoTrac RowSense in base equipment to closely follow the rows with less operator effort. In down corn, terraces, or pivots, it works efficiently while reducing operator’s stress.
All-day performance in all crops and conditions

No cornfield is perfect. John Deere corn heads make the best even better by offering features to help you tackle any field without hesitation, no matter how imperfect the conditions might appear.

  • Match changes in stalk and cob size throughout the field - with on-the-go robust, reliable, and low maintenance (compared to Drago) hydraulic adjustable deck plates.
  • Quickly harvest less-than-ideal fields – Down or leaning crop is no problem with Active End Fenders. They improve harvest in down or flat stalks by letting you maintain a consistent speed without worrying about losing ears. It’s a benefit you’ll notice in the down crop, but it can be equally crucial in standing crop. Plus, Active End Fenders reduce the need to stop and clear crop buildup from the outer row-units.
  • Decrease harvest loss – Longer end fender extensions on rigid and folding corn heads rise higher in the air to help save ears from being tossed over the side. This industry-unique end fender allows you to use the extensions and Active End Fenders together while still using them independently. On folding corn heads, the end fender extensions automatically lower when folded.
Treat residue like an asset rather than an afterthought

John Deere CF and CR Corn Heads are built to handle corn residue. You can start managing residue right away during harvest by appropriately sizing and distributing the residue evenly across your field to speed decomposition and improve soil warming to make planting manageable and effective.
