All rotors are manufactured with a double flange, and 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? 

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 holder-bolt 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 internal structure of Berti mulchers is entirely made of Strenx® steel – a high-strength, low-weight material that ensures an excellent balance between robustness, elasticity, and structural precision. Each housing is designed for long-term durability.

Using Strenx® allows for a lighter structure that is still resistant to torsional stresses, improving machine handling and reducing overall wear.

Berti’s craftsmanship and decades of design experience make the housings of their mulchers a benchmark for quality, reliability, and solidity – essential for operators working daily under challenging conditions and requiring consistent performance over time.

The mulchers for green areas, set-aside, heavy vegetation are equipped as standard* with an automatic belt tensioner.

This device eliminates the need for manual adjustments, as it automatically compensates for the natural elongation of the belts over time, ensuring consistent power transmission and reducing routine maintenance.

The automatic tensioner also simplifies belt replacement operations – belts can be removed easily by hand, without tools, making maintenance faster, safer, and more accurate.

Reliability, convenience, and uninterrupted operation – three tangible benefits that reflect Berti’s attention to construction details and the real needs of operators.

The bolted-on ending roller is designed to offer maximum efficiency, durability and ease of maintenance.

Thanks to its design, it is possible to increase load-bearing capacity, reduce the frequency of lubrication compared to standard rollers and, in the event of damage, replace individual components rather than the entire assembly.
