4 Advice to Choose a row crop header

What is the difference between a row crop header and a corn head?

Corn is one of the most produced and consumed cereals worldwide, and to ensure efficient harvesting, farmers use specialized machinery tailored to the crop’s characteristics. Among the most vital tools in corn harvesting are combine headers, and here, we will focus mainly on the differences between a row crop header and a corn head.

Row Crop Headers: These are designed to handle a variety of crops planted in rows, such as soybeans, sunflowers, and cotton. These headers are versatile and are characterized by guards and blades that allow cutting the crop close to the ground while preserving the integrity of the rows.

Corn Heads: In contrast, corn heads are specifically designed for corn. They have tines that fit between the rows of corn, detaching the cobs and allowing them to be processed by the machinery, while the rest of the plant remains in the field.

How wide is a 12-row corn head?

The width of a corn head is typically measured by the number of rows it can harvest simultaneously and the spacing between these rows. For a 12-row corn head with a standard spacing of 30 inches (approximately 76 cm) between rows, the total width will be approximately 30 feet (approximately 9 meters). However, it’s important to mention that the width can also depend on additional factors such as the presence of extra parts on the machinery or specific design features.

Why is corn grown in 30-inch rows?

Cultivating corn in 30-inch rows has been the standard practice in US agriculture and many other regions for decades. The reasons behind this method of cultivation are diverse and range from efficient use of space to resource and machinery optimization.

Optimization of Sunlight: 30-inch rows allow each corn plant to have more equal access to sunlight, which is vital for photosynthesis and, therefore, the healthy development of the crop.

Efficient Water Use: This spacing also optimizes water use as it allows for uniform irrigation and minimizes wastage.

Maximization of Production: Additionally, 30-inch rows are ideal for maximizing the amount of corn that can be planted in a specific area, balancing production per hectare.

Adaptation to Machinery: Agricultural machinery, such as planters and harvesters, has been designed to accommodate this specific row spacing, making planting and harvesting processes more efficient and less labor-intensive.

Proper Combine Header Selection for Midwest Crops

Harvest is more than just a season–it’s the result of months of planning and hard work. To get the most out of your harvest, you need efficient tools. That means matching the best combine header with your specific crops to ensure maximum yields. For Midwest staple crops like corn, wheat, and soybeans, the right combine header makes all the difference in minimizing loss and maintaining crop quality. Now, let’s break down the importance of header selection for your Midwestern harvest. 

Corn: Row Crop Header

Farmers in the Midwest–especially Indiana and Ohio–are no strangers to corn harvesting. A corn head, or a row crop header, is designed specifically to strip ears from stalks and effectively manage residue. 

Recommendations

  • John Deere Corn Heads are designed to maximize yield and reduce transport time between fields. Browse all corn heads for desired residue control, profile, stalk deflectors, and more. 
  • Look for key features like row spacing compatibility, hydraulic deck plate adjustments for varying stalk sizes, and stalk roll options based on desired residue. 

Soybeans: Flexible Draper or Auger Header

Soybeans grow close to the ground, and losses from missed pods can add up quickly. That means the ideal header should neatly hug the terrain for minimal crop loss.

Recommendations

  • John Deere’s RDF HydraFlex drapers are designed to harvest crops as close to the ground as possible, minimizing unnecessary loss. 
  • For smaller operations and flatter fields, consider a flex cutting auger platform. Where terrain is simple, opting for a flex auger header can help to cut down on cost.

Wheat: Draper Header

Wheat can be a fragile crop, especially in high-yield operations. For straight cutting taller crops like wheat, a draper header is an excellent choice, ensuring even feeding to maintain throughput and reduce product loss. 

Recommendations

  • On flatter fields, opting for a rigid draper platform will result in a faster, more efficient harvest. On heavily varied terrain, a flexible draper platform will work slower but maximize yields.
  • Leverage Active Header Height Control with your X Series or S Series Combine to minimize crop damage.
