Negri - R70 - Bio-shredders (Work)


The R70 bio-shredder is a hobby machine designed for the reduction of wood deriving from the maintenance of green areas, up to a maximum diameter of 50 mm.

The following cutting system is installed in the machine:

  • Rotor with 1 sharpenable blade in hardened steel + 6 reversible hammers in hardened steel.

  • Reversible counter-blade - allows the blade to cut better and last longer.

The back blades allow the chips to be expelled directly without any additional fan with relative transmission, thus reducing maintenance and noise.

All versions are characterized by accurate technical choices:

  • Refining screws - guarantee the chips' small dimensions.
  • Ejection to 650 mm from the ground - allows the chips to be ejected into a container.

  • Safety device on the hopper - guarantees the operator’s safety, avoiding contact with the cutting tools in movement.

  • Handle and two big wheels - facilitate the operator while moving the machine.

The electric version is equipped with a direct transmission.

The petrol versions are equipped with a belt transmission.

All versions are manufactured in compliance with the latest European safety standards.
