BackPac—the dribble bar linkage for umbilical application systems

The Vogelsang BackPac dribble bar linkage is specially designed for spreading liquid manure with umbilical application systems. This linkage allows you to make best use of the effectiveness of the um-bilical application system. Precision distributors with high distribution accuracy, a carefully designed hose layout, and rigid end hoses ensure highly precise deposition of the manure into the growing crops, for optimal utilization of the nutrients. The BackPac dribble bar linkage impresses with its lightness, stability, and high flexibility. It is simply the most efficient solution, especially for consolidated holdings. Instead of being transported in a tanker, the manure is pumped via a pipework system directly to the field. There the pipe-work connects to the umbilical application system, for spreading directly on the field. With a working width of up to 30 meters, this technology offers both excellent soil conservation and maximum effectiveness. Its weight-optimized frame design gives maximum stability. For transport, it is positioned directly behind the tractor so the driver's view is entirely unobstructed, and it does not increase the width of the vehicle either.

The Vogelsang BackPac dribble bar system is the specialized device for umbilical systems with working width up to 30 meters. This system has been adapted perfectly to the requirements of these umbilical systems. The frame design ensures the greatest possible stability and is also weight-optimized. Customized section control makes the BackPac dribble bar system highly flexible as well. The system can always be folded up behind the tractor, whether the working width is 12 meters or even 30 meters. The driver's view therefore stays completely clear, and the transport width is not increased either.


The unit is designed to be mounted on a 3-point hydraulic system.
Liquid manure, a valuable commodity, must be spread evenly and reliably in the distribution hoses. Vogelsang precision distributors permit precise distribution of the nutrients with a distribution coefficient of less than 5 percent. This makes spreading a safe and reliable process without fluctuations – which also guarantees even plant growth.

The discharge hoses on the Vogelsang dribble bar systems all have similar lengths, thanks to the optimized hose layout. The liquid manure reaches the soil almost simultaneously from each one, and spreading across the entire working width and length is also guaranteed. This not only ensures optimum lateral distribution accuracy in the linkage, but also prevents the V shape that can otherwise form.
The dribble bar linkage adapts to the contour of the soil. This reduces the load on the vehicle coupling and the entire frame structure. It also means that the hose ends are kept close to the soil at all times, and ensures that the liquid manure is deposited precisely across the entire working width.
The hose is a key factor in spreading technology. As such, the hose material and composition of the plastic have been developed specially for Vogelsang over several decades. The combination of raw materials that we use for our special hose is characterized by high robustness, elasticity, and UV resistance. This makes the hoses resistant to the effects of chemicals and environmental influences. The unique manufacturing technique we use for our rigid end hoses brings additional benefits. The hose sections used as end hoses are always straight and absolutely dimensionally stable. Your advantage: there is no need for guide elements, which are heavy and prone to wear, and the hoses always remain open and do not stick. Furthermore, this rigid end hose configuration ensures defined strip spacing.


Comfort Flow Control (CFC) is the universal solution when it comes to shutting off hoses in any system: part-width section cut-offs, tramline switching or DropStop systems. The CFC is installed in the hose outlets of the spreader device, downstream of the distributor. Each hose or group of hoses can be shut off from the cab. The CFC is versatile and can be used in any unit – dribble bar systems, trailing shoe systems or tillage units.

When this option is selected, the flow of liquid manure and oil to one of the two precision distributors is sealed off. This allows you to adjust to a half-tramline over larger working widths and smooth out wedges in the field. It also prevents overlapping.
