BackPac – Lightweight, Stable, and Smart

Advanced slurry spreading equipment with towed nozzles or a towed hose system, designed for supplying slurry through hoses from a stationary supply system.

On large farms, especially in hilly areas, slurry spreading systems in which slurry is delivered through hoses from a separate source are being used more and more frequently. This solution is characterized by high work efficiency and positive effects on the soil, because there is no need to drive a heavy slurry tanker through the fields. The significantly lower weight of the tractor and its attached equipment reduces soil compaction.

Vogelsang-BeTEC offers the following solutions for these projects BackPac – a machine with a reinforced hitch structure, a stronger swivel hitch, and an optimally positioned precision slurry distributor.

The distributor, installed nearly in the center, ensures the correct position of the center of gravity when the device is folded. Improved hose layout and the ability to optimize their length helps maintain a more consistent flow of slurry.

Unique Features of Vogelsang-BeTEC BackPac Slurry Spreading Equipment

Less soil compaction

BackPac is designed to work with a slurry delivery hose system, eliminating the need to drive a heavy slurry tanker through the fields. The lower total weight of the equipment reduces soil compaction, which is particularly important when working in wetter or hilly fields.

Precise and even distribution of slurry

The BackPac is equipped with „ExaCut ECL“ or „ExaCut ETX“ precision slurry distributors, which ensure even distribution of slurry to the discharge hoses. The optimal distributor layout and coordinated hose lengths help maintain a consistent slurry flow across the entire working width.

Automatic Management of Headlands and Sections

BackPac's headland management feature allows you to stop slurry spreading across the entire working width or on a selected side of the machine with a single button press. The system automatically closes the corresponding valves, and with the „Comfort Flow Control“ (CFC) option, individual hose groups can also be controlled. This helps prevent overlap and ensures more precise slurry application when turning at the headlands.

Stability and Easy Handling

The reinforced frame, swivel-mounted drawbar, and optimally positioned center of gravity ensure stable operation of the machine even under the most challenging field conditions. The integrated electrohydraulic system is controlled via an ISOBUS terminal, and the optional flow and pressure measurement function allows you to monitor slurry delivery parameters and record the amount applied.

High quality and efficient work

BackPac is available in two types:

With a drag hose system—for spreading slurry on the soil surface.

With towable pressure tips—for precise spreading of slurry under the crops.

Flow and Pressure Measurement

Using the optional flow and pressure measurement function, the slurry supply pressure can be monitored directly on the tractor's terminal. This allows you to monitor the operation of the filling pump in the slurry delivery system and record the amount of slurry spread on the fields.

Integrated electrohydraulic system

The BackPac electrohydraulic system can be controlled directly from the tractor's terminal. The unit connects to the tractor via an ISOBUS interface, allowing all key functions to be conveniently controlled from the cab.

The Galulaukiai Management Function

A new slurry flow control feature allows the operator to stop slurry spreading on the right or left side of the machine with the push of a button.
When the headland management function is activated, depending on the selected settings, slurry spreading is either completely stopped or continued on only one side of the machine during turns. The system automatically closes the valves of the corresponding sections, shuts down the entire slurry distributor, and, using the „Comfort Flow Control“ (CFC) system, closes the corresponding discharge hoses.

Additional Features

„The “Comfort Flow Control" (CFC) system for deactivating individual sections of the working width.
Digital measurement of slurry flow and pressure, with data displayed on the tractor's terminal.
Automatic beam bending system.
Lifting mechanism.
