How does KUHN make a good bale?

The KUHN FBP (fixed chamber) and VBP (variable chamber) baler-wrapper combinations have a number of unique features that always create the perfect round bale. Even cutting quality, correct bale density, consistently filled bales, stable shape retention and firmly wrapped are what you can expect from bales produced by the KUHN FBP and VBP series.

Making a good bale is not easy in all conditions. We will address the main components of KUHN baler-wrapper combinations that contribute to a good bale despite changing crop conditions.

KUHN INTEGRAL ROTOR for quick and optimal crop intake

The pick-up tines cleanly collect the grass and feed it directly into the INTEGRAL ROTOR. The large augers on both sides of the rotor force the grass through the OPTICUT cutting rotor. This integral rotor facilitates a more consistently filled bale, uniformly filled right to the sides. The integral rotor is located just after the pick-up unit. This short distance maintains a short and compact inlet channel which guarantees quick crop intake.

After the rotor, the grass passes through the OPTICUT cutting system. Two options are available with a maximum of 14 or 23 knives. The operator can pre-select the number of knives used by retracting some of the knives in the inlet channel. Baling without knives is of course also possible. The knives are individually protected against foreign objects. This gives better cutting quality with as large crop throughput as possible and reduces the sensitivity of the knives to foreign objects. Less downtime and a better cutting quality.

KUHN bales retain their round shape

After the cutting system, the grass is fed into the bale chamber. In the balers with a variable chamber, the triangular starting chamber and the PROGRESSIVE DENSITY system guarantees the bale always forms correctly. The belts apply pressure on the bale from the starting core to the outer layers, maintaining a consistent bale pressure throughout the entire baling process, ensuring tightly formed bales that retain their shape. This ensures that a good, round bale can even be made with short, dry silage. Thanks to the variable chamber design, you can set the bale diameter yourself to range from small and manageable bales to large bales with savings on (wrapping) film.

The fixed bale chamber is designed with 18 fixed rollers, allowing the bale to rotate immediately as the chamber is filled. Sensors in the hydraulic tailgate cylinders help to achieve the correct bale density, bale size and bale fill (left/right). Binding the bales on both the FBP and VBP balers can be done using either net or film.

Film always correctly positioned thanks to the KUHN 3D wrapping system

After binding the bale, it is quickly transferred to the wrapping table without being damaged. This is particularly important if film binding is used. For this reason, after film binding, KUHN uses guide rollers on the bale transfer system that ensure the bale is transferred undamaged straight onto the wrapping table, then wrapping can start.

All VBP and FPB balers can be equipped with the optional, innovative 3D wrapping system. The rolls of film rotate a quarter turn after which the bale is first wrapped around the cylindrical part and then around the flat ends. The result is an evenly wrapped bale that retains its shape better than a conventionally wrapped bale. The 3D wrapping system ensures the film is correctly positioned and evenly distributed over the bale and the vulnerable bale shoulders are well protected. Thanks to the low height of the wrapping table, the bale can then be safely discharged without dropping or deforming it. This will ultimately benefit the storage capabilities of the bale.
