KUHN baler wrappers

KUHN baler-wrappers: combined technology for high-performance baling and wrapping

KUHN baler-wrappers occupy a central position in modern forage harvesting equipment. Designed to combine round bale baling and wrapping in a single machine, they meet the requirements of livestock farmers and agricultural contractors looking for high throughput, optimum silage quality and great reliability in intensive conditions.

The KUHN range of baler-wrappers includes several iconic models, notably the i-BIO+, FBP 3135, VBP 3200 and VBP 7100 series, based on different baling chamber technologies (fixed, variable and high-density). These machines ensure the formation of regular, dense bales, immediately wrapped to preserve the nutritional value of the forage.

In this comprehensive article, we take a closer look at the presses kUHN baler-wrapper combinations, how they work, their key technologies, their main models and their advantages for modern farms. The aim is to understand why these baler-wrapper combinations are today an essential solution for harvesting silage.

Principle and operation of KUHN baler-wrappers

A combined baler and wrapper in a single machine

A KUHN wrapping press performs two essential operations in a single pass:

• Round bale pressing

• Immediate wrapping with stretch film

The forage is first compressed in the baling chamber to form a dense, even bale. Once bound with net or film, the bale is automatically transferred to the wrapping table, where it is wrapped in plastic film to create an anaerobic environment conducive to lactic fermentation.

This process enables :

• Optimum forage preservation

• Reduced nutritional losses

• Saves time on the job site

• Better feed quality for cattle and sheep

As the bale is sealed immediately after formation, the risk of air ingress is limited, improving the stability and quality of the stored silage.

Key technologies of KUHN baler-wrappers

3D wrapping for optimum preservation

KUHN has developed 3D wrapping technology, which distributes the film more evenly over the entire surface of the bale. This technique first applies the film to the cylindrical part, where sealing needs are greatest, to exclude more air and preserve the bale's shape over time.

This innovation improves :

• Ball sealing

• Forage fermentation

• Long-term storage

• Reducing food waste

3D wrapping combines with IntelliWrap technology to optimize the amount of film used, while guaranteeing even coverage.

Pressing chambers for every application

KUHN wrapping presses can be equipped with different types of pressing chambers:

• Fixed chamber

• Variable chamber

• High-density (HD) variable chamber

The baling chamber has a direct influence on bale density and its suitability for different types of forage. In particular, HD models enable extremely high densities to be achieved, reducing transport costs and improving feed quality thanks to a greater quantity of forage per bale.

This diversity enables farmers to choose the technology best suited to their crops: grass silage, ryegrass, clover, haylage or straw.

The main presses kUHN wrappers

i-BIO+: the compact, versatile baler-wrapper

The KUHN i-BIO+ is a compact, fixed-chamber combination baler designed for farms looking for a light, maneuverable machine with good baling and wrapping quality. It is particularly suited to small and medium-sized operations wishing to produce efficiently wrapped bales with a moderately-powered tractor.

Its compact design makes it possible to work in small plots or on hilly terrain, while maintaining good operating stability. The i-BIO+ is thus an affordable solution for securing the quality of wrapped products without the need for heavy equipment.

FBP 3135: the fixed-chamber baler-wrapper for extreme conditions

The KUHN FBP 3135 is a fixed-chamber baler-wrapper designed for demanding wrapping conditions. It is particularly suited to wet forages and difficult crops, where regular bale formation is essential to ensure good preservation.

The fixed chamber produces very dense, homogeneous bales, ideal for silage making. This robust design also ensures high reliability in intensive conditions, making it a popular machine with dairy farms and agricultural contractors.

VBP 3200 series: the versatility of variable-chamber balers

Maximum flexibility for different cultures

The KUHN VBP 3200 series is one of the most versatile ranges of variable chamber balers. These machines are based on the VB 3260 or VB 3290 balers, combined with an innovative wrapping system to form a high-performance, flexible combination.

Thanks to their variable chamber, VBP 3200 models can adjust bale diameter as required, making them suitable for a wide range of crops and harvesting conditions. This flexibility is particularly appreciated when producing bales of dry hay, silage or straw.

VBP 3260 and VBP 3290 models

The best-known models in this series include :

• VBP 3260

• VBP 3290

These machines feature Progressive Density technology, which ensures progressive bale density to optimize bale shape and stability. They are also equipped with the OptiCut integral rotor, guaranteeing excellent cutting quality and an even flow of crop to the baling chamber.

This technology improves baling efficiency while limiting the risk of blockages, even with large swaths.

VBP 7100 series: high performance for agricultural contractors

Machines designed for intensive use

The KUHN VBP 7100 series represents the top of the range of KUHN baler-wrappers. It is designed for large farms, CUMAs and agricultural contractors working on large surfaces and requiring high throughput.

The flagship model in this range, the VBP 7190, can form bales up to 1.85 m in diameter thanks to its high-performance variable chamber.

Its oversized components enable it to work in intensive conditions, on uneven terrain or with large volumes of forage.

Fast, reliable ball transfer

The bale is transferred to the wrapping table using a system of successive arms, enabling transfer in just a few seconds, guaranteeing continuity of work without loss of time.

This system ensures :

• A high work rate

• Reduced downtime

• Better overall productivity

The advantages of KUHN silage balers

Better forage preservation

Immediate wrapping creates a hermetically sealed environment around the bale, promoting controlled fermentation and limiting dry matter losses. This guarantees the high nutritional value of stored forage, essential for feeding cattle and sheep.

High productivity on the job site

By combining baling and wrapping in a single machine, KUHN baler-wrappers reduce the number of passes through the field and increase overall productivity. A single machine and a single operator are all that's needed to carry out the entire wrapping operation.

Versatility for all types of forage

KUHN baler-wrappers are designed to work on a wide variety of crops:

• Grass silage

• Ryegrass

• Clover

• Haylage

• Hay

• Straw

This versatility makes it an essential tool for diversified farms.

The importance of choosing a KUHN baler-wrapper

Adapting the machine to the size of the farm

The choice between an i-BIO+, FBP 3135, VBP 3200 or VBP 7100 baler-wrapper depends mainly on :

• Herd size

• The volume of forage harvested

• Working conditions

• Level of automation required

The compact models are suitable for individual farms, while the VBP 7100 series is aimed at intensive structures and agricultural contractors.

Conclusion: KUHN baler-wrappers, a complete solution for safe silage making

KUHN baler-wrappers represent a complete technological solution for baling and wrapping forages. Thanks to their different ranges - i-BIO+, FBP 3135, VBP 3200 and VBP 7100 - they meet the needs of all farms, from the smallest to the most intensive.

Their ability to produce dense, perfectly formed bales that are immediately wrapped ensures silage quality, improves forage preservation and optimizes work site productivity. By combining robustness, technological innovation and versatility of use, KUHN balers are today the strategic choice for livestock farmers wishing to maximize the quality of their animal feed and the profitability of their harvesting operations.
