Felling Heads
K-models are reliable combinations of felling head and loading grapple. They are suitable for all types of clearing and thinning of trees and bushes. The felling head is quick to attach instead of the crane's own loading grapple or harvester grapple without additional hydraulics.
Naarva K23
Felling head for tractor or forest wagon loader
Naarva K23 felling head is easy and quick to connect instead of the tractor's own timber grapple. With it you can fell, collect, cut and load trees, bushes and branches efficiently. Despite the light weight, the K23 felling head cuts a 23 cm thick tree effortlessly. The claws compress around the tree and a separate cutting cylinder pushes the blade through the tree with 95 kN force. The felling head can be easily turned from felling position to loading position with a tilt cylinder.
Naarva K24
Felling head for tractor or forest wagon loader
