High efficiency, less effort with Corn Head Automation features
Auto adjustable deck plate cane sensor
Available only on Ultimate Tech Package, Corn Head Automation enhances harvesting efficiency by automatically adjusting critical settings to optimize performance in varying crop conditions. This technology reduces operator workload, improves throughput, and minimizes grain loss.
Auto Adjustable Deck Plate: The system uses a cane sensor mounted on the corn head row unit to continuously measure stalk diameter variety. Based on these readings, it automatically adjusts the deck plate spacing in real time to match crop size and conditions.
Customer Benefits:
- Optimized ear retention: Keeps ears intact while minimizing kernel loss.
- Adaptability: Responds instantly to changing crop conditions without operator intervention.
- Reduced operator workload: Eliminates the need for manual adjustments during harvest.
- Improved efficiency: Maintains consistent performance across the entire field.
Auto BackShaft Speed: The system automatically adjusts the corn head back shaft speed based on combine ground speed and crop load. As the combine accelerates or slows down, the back shaft speed is regulated to maintain optimal crop flow and prevent overload.
Customers Benefits:
- Consistent crop flow: Prevents bottlenecks and uneven feeding.
- Reduced wear and tear: Avoids excessive strain on gear cases and row units.
- Higher productivity: Maintains throughput without manual intervention
- Operator comfort: Eliminates constant speed adjustments during harvest.
Corn Head Automation allows operators to focus on harvesting rather than constant adjustments. This results in Higher productivity and lower operator fatigue.

Consistent feeding and easier cleaning with High Slope Cover
X9 1000 Combine with CF 18 Corn Head with five center crop dividers with High Slope
The High Slope Covers are an innovative design enhancement for CF and CR corn headers. They feature an increased slope angle on the deck covers, specifically engineered to handle challenging fluffing conditions during corn harvesting
- Improved crop flow: The steeper slope prevents residue and husks from accumulating on the deck, ensuring smooth material movement toward the auger.
- Reduced blockages: Minimizes downtime caused by crop buildup in high-residue or fluffy corn conditions.
- Enhanced productivity: Maintains consistent feeding, allowing operators to harvest at optimal speeds without interruptions.
- Lower cleaning effort: Less material retention on covers means reduced time for cleaning and maintenance.
In fluffing conditions, traditional designs can lead to crop accumulation, feeding issues, and accelerated wear on critical components. The combination of High Slope Covers and Chain Paddles solves these challenges by improving residue shedding, actively moving crop, and protecting the row unit chain for longer service life.

More bushels per hour and more acres per day
X Series Combine with CF18 30 Corn Head (45 ft [13.7 m] wide)
You have more acres to harvest, which means starting harvest earlier 鈥� and sometimes at moisture higher than 32 percent 鈥� to get all your work completed on time. The solution is the CF and CR Corn Heads from John 91黑料专区. Available in a wide range of row spacings, these corn heads match the capacity of John 91黑料专区 combines, letting you harvest up to 7,200 bu (253,721 L) per hour in high-yielding, dry corn. With the new CF18 30 expect 11 percent less passes / quarter section with the CF18 30 versus CF 16 30. 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 鈥� The larger, 19-in. (48.3-cm) auger with increased torque helps you cover more acres per hour than John 91黑料专区鈥檚 current 700C Corn Heads. This ensures you can harvest high-yielding or high-moisture corn with ease. What鈥檚 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庐 system.
- Relax and enjoy worry-free, automated, on-the-go unloading 鈥� The massive capacity boost of an X Series Combine with a 16-row corn head means you鈥檒l 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鈩� Row Sense鈩� is the perfect choice whether you harvest six or 18 rows at a time 鈥揟o 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鈥檚 stress.

All-day performance in all crops and conditions
John 91黑料专区 corn head harvesting corn
No cornfield is perfect. John 91黑料专区 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 鈥� 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鈥檚 a benefit you鈥檒l 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 鈥� 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
CR12 Corn Head with Stalk Deflectors
John 91黑料专区 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.
- Size residue right at the corn head 鈥� Compare the RowMax Chopping Stalk Rolls to similar competitive models from Calmer庐 and the benefits are easy to see. RowMax Chopping Stalk Rolls provide 30 percent better wear life, consume less power, and keep more trash out of the combine. They also size 50 percent of the residue less than 6-in. (15.2-cm) long, which speeds breakdown and burial without washing or blowing away in the field.
- Reduce tire and track wear while increasing trade-in value 鈥� Minimize tire and track damage with John 91黑料专区 Stalk Deflectors that are one-fifth the weight of Lankota庐 Stalk Stomper庐 equipment. John 91黑料专区-designed and factory-installed Stalk Deflectors are lightweight and directly installed onto the frame. Set behind each row, they fracture corn stubble by pushing it down toward the ground, reducing the chance of damage to the tires and tracks of your combine, as well as any other equipment you take into the field. Not only does it extend the life and increase the trade-in value of your tires, but it also reduces overall maintenance costs.

Harvest down crops with confidence
Wind damaged corn can be very difficult to harvest
You have little control over the challenges that weather can bring. Wind damaged crops are often blown down, hiding the rows and making it nearly impossible to see where to harvest. The AutoPath鈩� system addresses these issues by providing accurate guidance lines even when the crop rows cannot be seen.
- AutoPath uses data gathered during the source operation (first pass) to map the location of each crop row. This data is used to create a series of guidance lines for the entire field which precisely follows the crop row, regardless of crop condition. You no longer need to manually create or reuse guidance lines, which can be very difficult when crop is down.
- AutoPath guidance lines position the machine accurately to start in the right place. When harvesting down crop, it can be nearly impossible to know where to start operating. AutoPath gives you accurate starting points for opening new fields, even in tough field conditions.
- AutoPath guidance lines track crop rows accurately, even when rows are not visible. When operating in the field with down crop, it is disorienting to manually drive the machine. Twisted down crops make it easy for you to move off the proper line, increasing harvest time. AutoPath lines accurately follow crop rows, even when they are not visible.
- AutoPath guidance lines allow the operator to focus on other important tasks. Harvesting in down crops can be overwhelming. Dealing with down crops increases the chance of slugging the machine. Unloading on the go is even more challenging in down crops. AutoPath gives you accurate guidance in all conditions, including down crops. This allows you to focus on other important tasks like crop feeding or unloading.
