Field performance: How the Fiellday ЖНС-4 handles the load

When you head out into the field to harvest sunflowers, the main issue isn't the speed of the combine, but how cleanly the header works. The Fiellday ЖНС-4 is a predictable machine in this regard. Throughout my time operating it, it became clear: this is a reliable, no-nonsense piece of equipment that is forgiving of minor setup mistakes. Its main advantage is the simple design of the lifters. They don't clog, even when harvesting high-moisture stalks, which saves a lot of stress during the peak season.

Operation and Maintainability

For a mechanic, this is a very straightforward machine. Access to the main components is open; you don't have to be a gymnast to tighten the drive chain or replace a finger on the cutter bar. Parts for the ЖНС-4 are standardized, which is a huge plus: if something goes wrong in the field, you don't have to wait weeks for parts from abroad. The bolted joints hold up well against vibration, although after the first 50 hectares, I strongly recommend going over the entire frame with a wrench—settling is inevitable.

Key Takeaways

• Losses: When the header angle is set correctly, sunflower head losses are minimal. It is crucial to monitor the gap between the lifter plates.
• Adjustments: The hydraulics work smoothly without any jerking. Adjusting the reel is intuitive and allows for quick changes based on sunflower height.
• Efficiency: Due to its lightweight construction, the load on the combine's feeder house is reduced. This leads to a 5–8% fuel saving compared to heavier analogues.

Of course, this isn't a premium segment machine loaded with electronics, but in agriculture, it's this kind of durability that counts. The Fiellday ЖНС-4 earns its keep by simply doing the job day after day without requiring major overhauls during the off-season.
