BE 20 Kuhn BE 20 Specifications & Technical Data (2018—2026)

A pivoting hood for most working conditions

The pivoting hood provides greater versatility. It can be adjusted according to the quantity and type of plants to be shredded.

Important Points for an Increased Service Life

The coupling device ensures that the tractor/tool link is very rigid.The free wheel is integrated in the gearbox as standard.A double skinned hood is available as option.

Easy Tool Exchange

The rear hood can be lifted manually for better access to the rotor. Therefore the shredding tools can be changed in total ease.

Make Your Life Easier!

Limited Maintenance You will benefit from the maintenance-free rotor thanks to bearings that are greased for life. Also the free wheel in the central gearbox needs no maintenance. Hydraulic Offset BK 230 and BK 280 shredders can be fitted with hydraulic offset of 40cm to the right to shred in fields with obstacles: orchards, rocks, etc. Lengthways Transport The BK 320 can be transported lengthways for passing narrow paths and roads at ease.

Easy and fast maintenance

Changing tools is easily made through the hood opening. As for the belts, you only have to remove one bolt on the guard to have access to the belts.

One Passage, Three Operations

Windrowing is provided by a worm screw attached behind the rotor. This is driven by a hydraulic motor connected directly to the tractor. Rotation speed can be adjusted to adapt to the working conditions (quantity of material, forward speed). The shredded product is discharged uniformly via a central opening at the back of the shredder. This avoids crushing by the tractor wheels. Baling, in combination or not, will be all the easier.

For Each Use a Shredder!

Requirements for shredders, intended for agricultural use and landscape maintenance, differ according to the shredded material, prevailing conditions and operator demands. In the vast KUHN range of agricultural and landscape shredders, you will find a model for almost every situation.

High-Quality Shredding is Most Important

Well-shredded crop residues and green spaces are a friend for your soil when fighting weeds, pests and diseases and for rapidly transforming organic matter into humus. This is best achieved if the residues are shredded very finely, the working height stays uniform, and the residues are spread regularly over the surface.

Why shred?

On pastures and fields, shredders have multiple areas of operation and agronomic benefits. An adapted crop residue management is an integral part of today’s agricultural production systems, especially in conservation agriculture, where crop residues are normally not ploughed under but only incorporated superficially into the soil. Fine shredding and a uniform distribution are the key points: to accelerate decomposition and conversion into humus, to provide favorable conditions for uniform germination of the subsequent crop, to control certain pests, diseases and weeds.

Maintain or improve pasture quality

Cattle pick out the best grass to feed on, leaving less attractive species on the pasture. If this low-quality grass is not shredded, it will spread through seeds or vegetative propagation. This reduces pasture quality on the whole and consequently also animal productivity.

Supporting soil fertility

To improve soil fertility, incorporation of organic matter into the soil is the most important measure. The finer the residues are shredded, the bigger the surface area for microorganisms to attack and transform the organic matter into humus. Strong points for high humus content include improved capability to retain water and fix nutrients, reduced nutrient leaching, improved soil structure and stability, and increased biological activity.

Don’t let weeds in

Weeds migrate from field borders into the plot. Shredding the grassy strips along the edge of the field is a good preventive measure to limit the spread of brome grasses.

Shredding quality and technology at its best

KUHN’s agricultural and landscape shredders are developed based on two main challenges: robust machines for long service life, high shredding quality, meaning complete and fine shredding of all residues on the field, intermediate crop covers, and undesirable growth or grasses on pastures.

Kuhn advantages for optimal shredding

Concrete technical solutions are numerous and versatile, as is the product range of our landscape and field shredders. Each one is optimally adapted or adaptable to its intended use and prevailing conditions. However, all of them feature common specifics for improved shredding work as well as more robust and reliable machines. More about the KUHN advantages can be found in the overview below!

A versatile family presents itself

From landscape maintenance work in parks and gardens to the upkeep of all kinds of green spaces and orchards: The KUHN range of landscape shredders will perform excellently in low to medium amounts of residues. With its short tools and adapted casing size, the machines are perfect for working in grassy areas.

Ideal for green spaces

Height control by roller Forward roller position: for perfect ground following, roller self-cleaning by means of the tools, projection of shredded residues over the roller to prevent compacting shredded grass and to facilitate its decomposition for a perfect result.

Quick Decomposition of Residues

Thanks to the optimized casing and roller position, shredded grass is ejected over the roller and consequently can’t get compacted. It is evenly delivered at the rear, where the decomposition can start immediately without delay.

A truly multipurpose range

With KUHN multipurpose shredders, you have a range of shredders suitable for maintaining pastures and fallow land, but also for destroying intermediate crops and plant cover.

Easy management from grass to brushwood

VKM shredders are designed primarily for use in pastures and fallow land, but can also be used for shredding prunings. With the VKM, you will find an adaptable multipurpose shredder best suited to your needs!

When Shredding Becomes Everyday Work

BP 10 and BPR 10 series shredders are designed for shredding all kinds of grassy areas, from managing weeds at the edge of fields to maintenance work on pastures or the upkeep of parks and gardens. This multipurpose shredder offers excellent value for money for individual crop and livestock farms and local authorities for daily shredding operations. With their front and rear-mount options and lateral offset feature, BPR 10 series models are the perfect solution for diverse conditions and difficult-to-access corners.

A Range to Cope with High Amounts of Residues

Well-shredded crop residues are beneficial for you and your soil, fighting pests and diseases and rapidly transforming the organic matter into beneficial humus structures. Discover the KUHN range of field shredders, which provide fine shredding and good spreading for all necessary jobs in the field!

The Meaning of Efficient Shredding

Shredding improves the decomposition of crop residues. A satisfying result is achieved if the majority of residues are less than 5cm long, the shredding height is uniform, and the residues are distributed regularly over the soil after shredding. With KUHN shredders, you can count on proven solutions to achieve these requirements.

Control the shredding height

The shredding height is adjusted either by pivoting wheels that are adjustable in height and laterally for shredding crop residues, or by a roller for management of set-aside land and grassland. For improved contour following, the 3-point linkage is in a “floating” position.

Adapt Shredding for Crop Harvest

The rotor speed is reduced to achieve shredding lengths of more than 15cm. Only then can they be baled. If you need finer shredding, we recommend the use of a shredder under the baler. The roller can be adjusted to provide the desired cutting height, from 4 to 15cm.

Practical and safe transport

For a machine of this size, innovative transport solutions have to be found. On the RMS 820, both the hydraulic transport device and the hydraulic drawbar are fitted with double acting cylinders with pilot-operated valves. Both safe and practical!

Bp 24 / bp 28 / bp 30 bpr 22 / bpr 24 / bpr 28 / bpr 30

The range for lighter jobs with both rear (BP) and reversible (BPR) versions with working widths from 2.10 to 3.03 m.

A compact unit

The VKM is equipped with an offset by sliding tube (mechanical as standard, hydraulic as option). This design allows the machine to gain in compactness with a centre of gravity close to the tractor.

Different Linkages

BP 24/28/30: Fixed Linkage On BP 28 and BP 30, the gearbox is positioned centrally due to a fixed central frame. The hitch pins are supported at each end. BP 24/28/30: Shiftable Linkage The linkage frame can be shifted mechanically or hydraulically on a sliding tube and comes with an off-centre gearbox to provide an extended offset of up to 45cm to the right. Frame and top link are connected via an articulated rod for improved ground contouring. BPR 22/24/28/30: Dual-Purpose Linkage with Lateral Offset The BPR’s double attachment frame can be front or rear mounted by simply inverting the transmission. These models are fitted as standard with a hydraulic lateral offset of the hitch frame by 45cm. For increased reliability and compact machine dimensions, it is displaced by sliding it over two tubes guided on Teflon rings.

A structure to last

The hitch frame design, a lasting structure of assembled parts, is especially robust. As standard, the BP 100 models can be offset mechanically by 58cm to the right. This is obtained using a sliding double tube system (one lower and one upper tube). This design reduces the machine overhang and limits stress on the hitch frame when working in offset position. The hitch pins are blocked and thus stopped from rotating. The upper link is equipped with a long hole for improved following of irregular grounds.

Offset by sliding movement

The sliding offset of 58cm allows it to reach the most difficult to access corners. The BPR 100 models are equipped with a hydraulic offset as standard.

A versatile implement

The BPR 100 PRO can be easily attached to the front or rear of your tractor. As with the BPR 100 models, the BPR 100 PRO range is also equipped with a 580mm hydraulic offset as standard. The shredder slides on two tubes of 70mm diameter, including Teflon bushes and greaser for more reliability.

High resistance to stress

The main frame is made up of heavy profiles that ensure good rigidity and mechanical strength. Moreover, each half shredder is fixed to the main frame with a bushed pivot pin that cannot rotate and therefore prevents the whole attachment from wear.

For uniform germination of subsequent crop

Finely shredded and homogeneously distributed residues facilitate precise seeding of the subsequent crop. There shouldn’t be many undecomposed maize or cereal straw left that could hinder a regular germination and crop growth.

No home to pests and diseases

In close crop rotations with high shares of maize and wheat, pests and diseases find a wonderful playground to develop. Shredding is an effective instrument to destroy the maize stems, which serve as winter retreats of pests such as the European corn borer. An accelerated decomposition, moreover, ensures that no residues rest on the surface until the next wheat flowering to avoid the transmission of fusarium spores.

An Ally in Maintenance

Offset possibility, adjustable rear hood, different tools to choose from: Owing to its versatility, this shredder is able to meet very varied applications such as maintenance of pasture land, orchards, unsown areas, but also shredding crop residues or intermediate crops.

Adding versatility

With a reversible BPR shredder you can enjoy the benefits of maintaining pastures and fallow land. It will also enable you to shred crop residues. When in frontal position, the tractor does not drive over the plants, providing smoother shredding action. A BPR fits all tractors: It is coupled at the front or back. Work can also be done with a front and back combination including the KUHN verge maintenance equipment or hedge and grass cutters.

Considerable shredding output!

Contractor or large-farm owner, the BP 8300 multipurpose shredder is made for you. As a triple combination with a BPR 280 PRO or BPR 305 PRO, output rates are impressive with working widths reaching 8.30 m. It is mainly designed for the maintenance of pasture, fallow land and grassy areas, but its versatility means it can shred plant cover (mustard, phacelia...) as well as crop residues and maize stubble. The tractor wheels do not run over the residues, so intake into the shredding units is easier.

Three Criteria for Impeccable Shredding

A large diameter rotor, a sufficient overlap between the tools and a high linear tool speed: If these three conditions are fulfilled, nothing stands in the way of superb shredding results. KUHN meets these criteria with its rotors, adding also the helical tool layout in order to increase the suction for an improved cut and even residue distribution over the soil.

High-quality mowing and shredding

Specific articulated scoop knives care for superb grass mowing operations, as does the high number of tools. A counter knife in the casing enhances the shredding quality.

Excellent Ground Follower

The working height is set by a 160mm diameter roller with fixed ends, mounted on double-row ball bearings with greasing points. It is positioned very close to the rotor, ensuring the best possible adaptation to the terrain. Another advantage is that the roller is automatically cleaned by the shredding tools!

Optimized Design for Superior Work

The optimized shredding casing profile ensures that large volumes of plant residues can be shredded while limiting power consumption. Equipped with a roller positioned very close to the rotor, the machine follows the ground perfectly and achieves improved decomposition.

Less Wear, Improved Protection

The optional bolted 4mm thick sheet metal lining inside the casing minimizes wear and provides protection against foreign bodies. Select the roller with removable ends and fitted with reinforced roller bearings that only need minimum maintenance and reduce replacement costs.

For Even Better Ground Following

The skids combined with the roller protect the side walls, improve the machine's stability, and provide additional guidance.

Bp 8300

Two side-shredding units combined with a central unit, BPR 100 PRO, for a large working width of 8.30 m.

High-quality shredding

The helical layout of tools on the VKM rotor is optimized for: smooth rotation without jolts, good suction for a clean cut, even distribution of shredded residues for improved decomposition.

Reliability of the Roller with Removable Ends

Double row of ball bearings for increased longevity, perfect sealing through chicanes and greasing system. The roller is fitted closest to the rotor for efficient ground hugging and self-cleaning by means of the shredding tools.

A Universal Design

The low construction with rounded edges, internal rotor bearings, and smooth sides with no sharp edges facilitates shredding almost everywhere, including under trees and vines. It can also be equipped with raking tines for ligneous residues. With an adjustable rear hood, the shredding degree can be adapted to the amount of residues.

A Robust Structure

Long service life and resistance against impacts is an important issue for KUHN. Therefore, the casing of BP/BPR 10 series shredders consists of a 6mm thick sheet metal lining and 8mm thick side walls. The two counter-blades (1 notched, 1 smooth) are welded on the casing.

Performing Shredding Unit

The helical tool layout on the rotor ensures a perfect residue suction and homogeneous spread over the ground behind the rotor. More strong points for a long-lasting and high performance include robust tool holders and anti-rotation attachment screws, a rotor speed of up to 2,356 min-1 for clean shredding, and high-capacity rotor drive by four SPBX V-belts.

Cutting Height Under Control Means Work Quality Under Control

For efficient shredding and plant cover preservation, it is essential to have control over the cutting height. Working height control is either done by: a 220mm press roller with fixed or removable ends positioned very close to the rotor for improved ground adaptation, grass ejection over the roller, and automatic cleaning by the tools (BP 10 and BPR 10). semi-pivoting wheels fixed onto the shredder casing (BP 10).

A Robust and Multipurpose Hood

The structure is made up of two beams including a welded sheet metal lining for increased resistance. The rear hood is adjustable; adjust it to the minimum for shredding slightly dense vegetation or maximum product recycling. Adjust it to the maximum when shredding dense vegetation or if you want to work faster while limiting the power input.

Shredding Casing: Longer Life

The standard model of shredding casing is reinforced by a 4mm lining for longer service life, and it is equipped with two counter blades (one notched and one smooth) for fine shredding.

High Outputs for Contractors and Large Farms!

BPR 280 and 305 PRO shredders are the ideal partners to the large-width BP 8300. Identical tools, tool holders, and number of counter-knives make for a homogeneous shredding job.

Designed for High-Quality Shredding

The 465mm diameter rotor is fitted with heavy hammer knives which are perfectly adapted for shredding pasture land, cover crops, and woody crop residues. For especially fine shredding, the BPR 100 PRO is fitted with two counter knives, with a third available on option. A pivoting rear hood makes adaptation to different volumes of residues possible.

High-Quality Shredding Results

The 465mm diameter rotor with helical positioning of tools, combined with a body equipped with a pivoting rear hood, means that the large width shredders can shred a large quantity of vegetation, even at high speed. Ejected above the press roller, the residues are not compacted, thus accelerating decomposition rates.

A Pro Structure

It also comes with a welded sheet metal lining for optimal protection against wear and impact, two counter blades for fine shredding (third optional), a pivoting rear hood to adapt to all types of working conditions, a press roller with removable ends 220mm in diameter, lateral skids, and a rotor with hammer holding pins (20mm diameter) made of special treated steel.

Rotor for Perfect Shredding

The high linear speed combined with the high level of overlap between tools ensures high-quality shredding. Moreover, you can shred large quantities of residues with the large rotor diameter.

Fine Shredding of All Types of Plant Residues

The universal knives with stubble pallets will lacerate the residues for faster decomposition. They also provide improved suction, especially of lodged crops into the hood.

Central Strip Managed Effectively

To reduce the central strip to a minimum, we have optimized the suction at the center of the machine. The flux of residues is directed into one of the units with an increased number of tools in this area and with a fitted divider share. As an option, a hydraulically driven disc can be mounted at the front between the two units to fully remove the residue strip in-between.

High Quality Work in Different Residues

A regular and fine shredding result is the aim to support soil microbes in their decomposition work. That’s why the BC and BCR 1000 shredders are equipped with: a large diameter rotor with eight rows of helically positioned working tools; this layout improves residue suction to the rotor and provides a homogeneous residue spread behind, a choice between hammer knives or universal knives with stubble pallets as working tools for optimal adaptation to the type of residue, two counter-knives welded inside the casing for a perfect shredding finish.

Bc 6500 R: Reliability Embodied

This large shredder with a working width of 6.50 m is built around 3 large section beams, a high-strength coupling, a high-capacity drive with POWERBAND belts, and a sheet metal lining which combines robustness and reliability. Its large diameter rotor (647 mm) fitted with heavy hammer knives ensures a high output during shredding of residues. Special "L-shaped" tools equip the rotor to ensure shredding of the central strip.

Reliable Machines That Eat Up Hectares!
