The largest model of the Naarva felling heads

The robust Naarva K32 felling head is capable of cutting trees of up to 32 cm diameter. The hydraulic system can be chosen based on the base machine used: a two-way system for excavators and trucks and one-way system for harvesters.

A versatile harvesting equipment for truck loader cranes

Naarva K32 felling head with Naarva radio control provides truck loader cranes with various new working methods:

  • removing problem trees in urban areas and residential plots
  • removing hedges, old poles, and posts
  • shortening branches
  • cutting and lifting of trees fallen on power lines, roads, and buildings

Trees and bushes that have been cut down can be lifted onto the bed of a truck directly, which makes harvesting safe and efficient in areas of restricted access. Thanks to the long extension capacity of the loader crane, all trees can be cut into sections from the top down, regardless of their height.

Guillotine options

Robust – maximum cutting power

  • Traditional Naarva guillotine
  • A two-phase cutting method:
    1. Grippers close around the tree
    2. Cutting cylinder pushes the blade through the tree
  • Max. cutting diameter: 32 cm; up to 50 cm in case of bushes and bundles of trees

Quick – productivity with small wood

  • A new, innovative Naarva guillotine
  • Cuts with one stroke
    1. Grippers press the tree against the blade that is forced through the tree
  • Max. cutting diameter: 28 cm
