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.
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.
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!
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.
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.
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.
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 Control Means Work Quality 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.
A Pivoting Hood for Most Working Conditions
The pivoting hood provides greater versatility and can be adjusted according to the quantity and type of plants to be shredded.
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 Shredder with Weight Reduction and Non-Stop Safety
The frame on the BP 8300 shredder is unique on the market. It is equipped with the same LIFT-CONTROL technology that is used on KUHN's large-width mowers and has exclusive features: Pendulum-type articulation on both shredding units for excellent ground hugging, a weight-reduction system for less stress on the roller, and non-stop safety combined with a shredding unit lift system to provide the machine with optimal protection against obstacles when moving rearwards. The lift system is built into the frame for easy maneuvering, resulting in perfect shredding and reduced costs!
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.
Shredding Tools
The rotor is fitted with four rows of tools to choose from: - universal knives with stubble pallets to lacerate the residues better: for stubble and cereals,
- long hammer knives for woodier material: maize and sunflower stalks, maintenance of hay fields.
Perfectly Controlled Shredding Height
Two working height control devices are available for these machines: - semi-pivoting wheels,
- roller. Wide height-adjustable skids are available as an option.
Control the Shredding Height
The shredding height is adjusted either by pivoting wheels adjustable in height and laterally for shredding crop residues, or by a roller for management of set-aside land and grass land. For improved contour following, the 3-point linkage is in a “floating” position.
A Tool for Each Need
- 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.
- The long hammer knives are adapted for shredding grass, maize, or sunflower stalks.
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.
Adapt Shredding for Crop Harvest
The rotor speed is reduced to receive 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.
