Compax: Comfortable liquid manure spreading with maximum accuracy

The Vogelsang dribble bar system Compax combines innovative spreading of liquid manure with modern self-propelled vehicles. Combined with a self-propelled tractor vehicle, this linkage is an excellent way to spread liquid manure that is easy on the soil. Vogelsang's design is also aimed at maximum accuracy in distribution, because that is the only way to make optimum use of the nutrients in the fertilizer. This is achieved with precision distributors with a variation coefficient of no more than 5%, an optimized hose layout, and rigid end hoses. Thus, preventing the characteristic "V shape" that can form at the start, and ensuring a set distance between the discharge lines, with precise deposition into the crops.

The dribble bar system Compax also boasts high flexibility and stability at the same time. It’s especially designed for the requirements of self-propelled vehicles that are in use around-the-clock during the fertilizing season. The system for the fluid, the hoses, and the precision distributor ExaCut used here are specially designed for high spreading capacity and maximum speed. The transport position is likewise unique.  No matter whether the working width is 12 meters or 18 meters, the Compax folds up completely behind the vehicle so the driver's view is not obstructed, and it does not exceed the width of the vehicle either.

The Compax dribble bar system — efficient spreading of liquid manure and maximum efficiency with a large working width and compact transport dimensions.

Features of the Compax

The unit is designed to be mounted on a 3-point hydraulic system.
Maximum hose diameter for maximum spreading performance from precision distributor to hose end, with a uniform DN 50 hose nominal diameter.
The Comfort Flow Control seals the discharge hoses, reliably preventing them from dripping.
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.

Options of the Compax

In order to ensure that the linkage follows the soil contour as closely as possible, the control can be used to adjust its angle.
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.
