SHREDDERS

Stalk choppers are designed to chop crop residues such as corn, sorghum, and other crops, facilitating rapid soil preparation for subsequent tillage operations. The product line includes models compatible with tractors ranging from 60 to 380 CV, offering high reliability and performance even in the most demanding applications.

The tube, produced by extrusion, requires no welding and is
therefore seamless – a guarantee of strength and reliability.
This manufacturing process provides enhanced resistance
to accidental impacts.
Square recess tool holders – why is this better?
When it comes to shredding, each design detail makes a
difference. The tool holder is one such detail.
The choice between a hexagonal and a square recess affects
not only the shape, it directly affects the holding strength
and clamping of the component.
This design feature translates into increased reliability,
durability, and operational safety.
The square recess allows for a more precise and stable
mechanical connection between the tool (hammer or knife)
and the holder.
This means:
• No play between parts, ensuring longer life of the
holderbolt connection.
• Reduced risk of slippage or rotation of the bolt.
• Greater resistance to dynamic and torsional stresses.
Each Berti rotor is tested and balanced at high speeds to
ensure top-quality performance

The Berti range of shredders for stalks offers you the
freedom to choose between hammers and blades, to tackle
any type of residue and always achieve excellent results.
Efficiency, quality and precision thus become your working
standard.
Blades: precision and speedlades guarantee:
• Fine and uniform shredding
• Clean cut that promotes rapid decomposition
Hammers: power without compromise. Hammers guarantee:
• Powerful impact on bulky materials
• Continuous operation even on uneven ground
• Maximum durability and reliability
Versatility that makes the difference
Choosing the right tool means optimising work, consumption
and agronomic results. With Berti, the machine adapts
to the job and not the other way around, for consistent
performance in all conditions. Every component in the range
is designed to withstand the test of time, ensuring safety,
robustness and concrete results, day after day.

Designed for optimum efficiency, durability, and ease of
maintenance.
Its fully detachable structure allows each component to be
replaced individually, avoiding the need to replace the entire
assembly in the event of damage.
Double roller bearings at the ends provide higher load
resistance and long service life, even in the most demanding
conditions.
The internally shielded chamber reduces the frequency
of greasing compared to standard rollers. The roller tube is
precision-machined to house the bearing assembly in
a perfectly protected seat, enhancing straightness and
structural strength.
Greasing is performed at the factory – the vent valve is
only for checking the chamber fill. The grease retains its
properties for over 1,000 working hours, requiring only
extraordinary maintenance.

Our range of stalk shredders is equipped with a high body, a
design choice that comes from field experience and the real
needs of farmers.
The increased internal volume in the chassis allows the
machine to accomodate and handle larger quantities of
crop residue, ensuring a wider, more regular and continuous
workflow.
Thanks to the high body, the material has more space to be
conveyed to the cutting unit, avoiding accumulation,
slowdowns and dispersion. This means:
• Better product absorption capacity, even in conditions of
particularly abundant residues.
• More uniform shredding, because the material flows more
smoothly inside the machine.

• Reduced clogging, especially on difficult terrain or in the
presence of long and voluminous stalks.
• Higher productivity, as the machine maintains constant
output even during the most intense phases of work.
The high body also optimises the interaction between the
rotor, counter-blades and air flows, improving the overall
efficiency of the cutting process. The result is finer, more
uniform shredding, which promotes rapid decomposition of
the residue and contributes to soil health.
In short, the high housing is not just a design detail: it is a
concrete functional advantage, designed for those seeking
high performance, reliability and operational continuity in all
working conditions.

Berti shredders for stalks are equipped as standard* with
automatic belt tensioners.
This device eliminates the need for manual adjustments, as
it automatically compensates for the natural elongation of
the belts over time, ensuring constant power transmission
and reducing routine maintenance.
The automatic tensioner also simplifies belt replacement
operations, as the belts can be easily removed by hand without the use of tools, making maintenance quicker, safer
and more accurate.
Reliability, practicality and continuity of work: three concrete
advantages that reflect Berti’s attention to construction
details and the real needs of operators*.
