BackPac – The smart trailing shoe and dribble bar system for umbilical slurry systems

On farms with rolling hills, applying slurry using an umbilical system has become a proven and effective slurry spreading method. This approach not only improves the availability of nutrients in slurry for better plant uptake but also reduces environmental impact by minimising nutrient losses. The absence of a heavy tanker means significantly lower ground pressure, helping to reduce soil compaction and protect soil structure.

Vogelsang’s answer to this need is the BackPac umbilical slurry system—designed with a reinforced linkage, a robust swivel joint, and a centrally positioned heavy duty slurry macerator. This central placement improves weight distribution when folded, ensuring a stable centre of gravity. Optimised hose lengths within the linkage ensure a consistent slurry flow, delivering reliable and efficient application across varying terrain.

Models of the BackPac

BackPac

The ideal dribble bar system for hosing systems

The BackPac dribble slurry technology from Vogelsang is a lightweight, high-performance solution, purpose-built for slurry application via umbilical systems. Engineered for easy compatibility with a range of towing vehicles, it delivers efficient, low-emission slurry spreading while minimising soil compaction—ideal for modern, high-demand farming conditions.

Thanks to its reduced overall weight, the BackPac slurry applicator protects soil structure and supports long-term field health. Its continuous, even slurry distribution improves nutrient availability for crops, and with four flexible working widths (21 to 32 metres), it ensures precision across all field sizes. Seamless folding without overhanging frame parts, along with slope compensation, automated headland management, and maintenance-free joints, make operation smooth and user friendly.

Additional features like individual hose group control and dimensionally stable end hoses allow for accurate, contamination-free slurry application directly onto crops—even on uneven terrain. With its smart design and reliable performance, BackPac sets the standard for efficient, adaptable slurry spreading with umbilical systems.

BackPac Slide

Lightweight with high impact force

The BackPac Slide trailing shoe is a lightweight, high-efficiency system built for precise slurry application with minimal soil compaction. Designed for umbilical slurry systems, it offers excellent adaptability and control—ideal for farmers, contractors, and machinery rings.

Its low total weight helps protect soil structure, while up to four working widths are available without any overhanging frame parts. Individually switchable hose groups and durable BaseRunner trailing shoes ensure accurate, low-emission slurry nutrient placement directly beneath crops for better plant uptake.

With slope compensation and fully automatic headland management, BackPac Slide delivers smooth, reliable performance on all types of terrain. Maintenance-free joints and working widths from 21 to 30 metres make it a practical, soil-friendly solution for efficient modern slurry spreading.

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.
Slurry, a valuable commodity, must be spread evenly and reliably in the distribution hoses. Vogelsang slurry macerators 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.
