Silage Header
Silage is a crucial feed source for livestock, particularly during times when fresh pasture is not available.
Silage headers are specialized attachments used on forage harvesters to efficiently cut and gather crops like corn, grass, alfalfa, and other green fodder, which are then processed into silage. These headers are designed for precision cutting, maximizing both the quality and quantity of the harvested material.
What is a Silage Header?
A
silage header is a front-mounted attachment for forage harvesters that is specifically engineered to cut and collect various crops destined for silage production. Unlike grain headers, which are designed for harvesting dry crops,
silage headers are optimized for green, high-moisture crops. They play a vital role in creating quality silage by ensuring that the forage is cut cleanly and efficiently, preserving the nutrient content.
The use of
silage headers is widespread in dairy and cattle farming, where high-quality silage is a staple in feeding programs. Silage headers can harvest both standing crops, such as corn, and cut grass or hay from the field.
Key Types of Silage Headers
There are several types of
silage headers, each designed for specific crops and harvesting conditions. The three most common types include:
1. Row-Independent Headers
Row-independent headers are versatile attachments designed to harvest crops like corn and sunflowers regardless of their row alignment. These headers are ideal for large-scale farms as they offer flexibility in operation and can cover wide areas quickly. They feature rotating discs that cut the stalks and feed them into the harvester for processing.
2. Grass Pick-Up Headers
Grass pick-up headers are used primarily for hay, grass, and alfalfa. These headers gather pre-cut grass from the field and feed it into the harvester. They are equipped with pick-up reels that lift the forage from the ground without causing damage, ensuring the material is clean and well-gathered for silage production.
3. Direct Cut Headers
Direct cut headers are designed for standing crops like small grains or legumes. These headers cut the crop at its base and feed it directly into the harvester, making them ideal for harvesting green crops destined for silage. They provide a clean cut, which helps to preserve the nutritional value of the forage during the ensiling process.
How Silage Headers Work
The primary function of a silage header is to cut the crop cleanly and deliver it to the harvester’s feeding mechanism. Here’s an overview of how the process works:
-
Cutting the Crop: The silage header’s rotating blades or discs cleanly cut the crop at the base, minimizing waste and preventing damage to the plant material.
-
Gathering the Crop: The cut material is immediately gathered by the header's pickup reels or augers, ensuring that no forage is left behind. Row-independent headers allow crops to be cut in any direction, while pick-up headers lift cut grass or hay directly from the field.
-
Feeding into the Harvester: Once gathered, the crop is fed into the forage harvester’s feed rollers. From there, the material is chopped into small, uniform pieces that are ideal for silage.
-
Blown into Trailers: After chopping, the silage material is blown into trailers that follow the harvester, ready to be transported to silage pits or storage bunkers for fermentation.
