Working Principle of Tractor PTO Driven Forage Harvester for Silage Harvesting

The working principle of a tractor mounted PTO driven forage harvester for silage harvesting involves several key steps, each contributing to the efficient cutting, chopping, and collection of forage crops. Here’s a detailed explanation:

1. Power Transmission: The forage harvester is mounted on the tractor and connected to the tractor’s Power Take-Off (PTO) shaft. When the PTO is engaged, it transfers mechanical power from the tractor’s engine to the harvester. This power transmission drives various components of the harvester, enabling it to perform its functions effectively.

2. Crop Gathering: As the tractor moves forward, the harvester’s gathering unit, typically consisting of rotating drums or pick-up reels, collects the standing forage crops. These gathering mechanisms are designed to lift and feed the crops into the harvester smoothly, ensuring minimal crop loss and efficient feeding.

3. Cutting Mechanism: Once the crops are gathered, they pass through a cutting mechanism, usually composed of sharp, rotating knives or blades. This mechanism cuts the forage crops at the desired height, based on the adjustable settings of the harvester. The precision cutting ensures uniformity in the harvested crop, which is crucial for consistent silage quality.

4. Chopping Unit: The cut forage is then conveyed to the chopping unit, where it is further processed into smaller pieces. The chopping unit typically consists of a series of rotating knives or flails that chop the forage into uniform lengths, ideal for silage fermentation. The chopped forage’s particle size can be adjusted based on the specific requirements of the silage.

5. Blowing and Collection: After chopping, the forage is blown through a chute into a trailing wagon or a truck for collection. The powerful blowing mechanism ensures that the chopped forage is efficiently transferred without blockages. The collection wagon or truck is usually towed behind the tractor, moving in tandem with the harvester.

6. Silage Compaction and Storage: Once the forage is collected, it is transported to a silage storage facility, such as a silo, bunker, or silage bag. Here, the forage is compacted to remove air, which is essential for the anaerobic fermentation process. Proper compaction and sealing ensure that the forage ferments correctly, preserving its nutritional value and preventing spoilage.
