Tree cutting process using shearing and rotation constraints continuously for performing the brush-cutting work, an assembly of arms turning at low revolution and with power to catch the tree, direct it and force it against a knife, the latter remaining fixed. Contrary to the traditional process, low fuel consumption, worker safety and almost non-existent maintenance requirements make this process very economical and eco-friendly.
Procédé de coupe d'arbre utilisant la contrainte de cisaillement et la
rotation
en continue pour effectuer le travail de débroussaillage, un ensemble de
bras tournant à faible révolution et avec puissance pour attraper l'arbre, le
diriger et le forcer à passer contre un couteau, ce dernier demeurant fixe. La
faible demande énergétique en carburant, la sécurité des travailleurs,
l'entretien requis demeurant presque inexistant en font, contrairement au
procédé classique, un procédé économique et très écologique pour
l'environnement.
