Objective of the invention is a pruning device for upright pruning of trees, to which pruning device belongs a shaft (1), an at the end (2) of the shaft through an articulated joint fastened support (3), an at the support fastened, rotatable cutting blade (4), an at the support fixed, with the cutting blade parallel running cutting support device (5) for leaning of the upright pruning device against the tree when cutting the branches as well as a with the cutting blade connected power source (6, 7) for the rotating of the cutting blade. When operating the present pruning devices the problem is the fact, that when using them the trunk of the tree is easily damaged, because the cutting is performed too close to the trunk of the tree. In the pruning device in accordance with the invention at the support (3) fastened on the end (2) of the shaft is fastened a fastening device (8), on which the cutting blade (4) is fixed adjustably parallel to the axis of the cutting blade for adjusting of the distance between the trunk of the tree and the cutting blade.
L'invention a pour objet un dispositif d'élagage vertical d'arbres, lequel dispositif comprend un axe (1), un support (3) fixé à l'extrémité (2) de l'axe par un joint articulé, une lame (4) rotative fixée au support, un dispositif de support (5) coupant fixé au support et fonctionnant parallèlement à la lame pour incliner le dispositif d'élagage vertical contre l'arbre quand il sectionne les branches, ainsi qu'une source d'énergie (6, 7) reliée à la lame et servant à la faire tourner. Les dispositifs d'élagage actuels présentent le problème d'abîmer le tronc de l'arbre, car la coupe s'effectue trop près du tronc. Dans le dispositif objet de l'invention, un dispositif de fixation (8) est fixé sur le support (3) relié à l'extrémité (2) de l'axe; la lame (4) peut se régler parallèlement à son axe sur ledit dispositif de fixation (8) afin d'ajuster la distance entre le tronc et la lame.
