BackPac – The intelligent trailing shoe and dribble bar system for umbilical application systems

Especially farms with rolling hills, liquid manure spreading via an umbilical application system has become an established method. Not only because supplying fertilizer via an umbilical application system is extremely effi cient, but also the fact that there is no tanker has a positive effect on the field: The considerably lower weight of the tractor and linkage protects the soil.

Vogelsang‘s solution is the BackPac with a more stable linkage and a stronger pull swivel as well as with a more strategically placed precision distributor: Mounted almost centrally, it provides a corresponding center of gravity when folded. The fact that the hose lengths in the linkage could also be adjusted as a result also contributes to a more constant flow of liquid manure.

BackPac

The ideal dribble bar system for hosing systems

The BackPac dribble bar linkage is a lightweight and highly adaptable solution specifically engineered for hosing systems. Designed for easy compatibility with various towing vehicles, BackPac dribble bar system delivers efficient liquid manure application with minimal soil compaction, ideal for today’s high-demand agricultural operations.

With its reduced total weight, the BackPac dribble bar linkage minimizes impact on soil structure, supporting long-term field health. Its continuous spreading capability ensures high impact and even distribution, while the system’s four flexible working widths and seamless folding mechanisms eliminate overhanging frame parts. Individual hose group control and dimensionally stable end hoses further enhance precise, contamination-free application directly onto crops.

Enhanced with slope compensation and automated headland and folding management, BackPac dribble bar system is user-friendly and designed to adapt to any field terrain. Maintenance-free joints ensure smooth operation, and working widths from 21 to 32 meters make it the efficient, flexible choice for modern hosing system applications.

Features of the BackPac

The unit is designed to be mounted on a 3-point hydraulic system.

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.

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.

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.

To prevent damage to the system and umbilical system as well as excessive liquid manure flow during turning, the control modules for hose groups and part-width valves can be preset so that they react automatically with a single push of a button when driving. If there are lifting devices on trailing shoe systems, they are also raised automatically.

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.

Options of the BackPac

The decision on dribble bar or trailing shoe depends on the condition of the soil and the growing crop. In both cases, the BackPac features facilitate liquid manure spreading using umbilical system technology and contribute to the application of liquid manure at the base of the plants for efficient use of nutrients while protecting the soil.

A digital pressure gauge is available for the BackPac system to monitor the pressure at which the pump is pumping the liquid manure into the umbilical system and onto the field. The measured values are transmitted to the terminal in the driver's cab so that the driver can react accordingly. Flow rate recording by a counter function enables the values to be assigned to specific customers or fields.

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.
