Le travail traditionnel de la terre dans un jardin s'effectue au moyen The traditional work of the soil in a garden is done by means
d'une bêche ou d'une fourche b4che qui permettent de retourner la terre. a spade or a b4che fork which allows to turn the earth.
Le geste necessaire à ce mouvement est très fatigant pour le dos et le The gesture necessary for this movement is very tiring for the back and

- Les figures 1 et 2 représentent les différents éléments du dispositif. - Figures 1 and 2 show the different elements of the device.
- La figure 3 représente l'outil monté. - Figure 3 shows the mounted tool.
En référence à ces dessins, l'outil se compose de 2 parties emboitables: 1' Un porte -outil que nous appellerons "porte griffe" (fig. 2) 2 Une denture que nous appellerons "griffe" (fig 1) I- Le porte griffe se compose de 2 manches coudés (1) faisant levier, With reference to these drawings, the tool consists of 2 nestable parts: 1 'A tool holder which we will call "claw holder" (fig. 2) 2 A set of teeth which we will call "claw" (fig 1) I- The claw holder consists of 2 bent sleeves (1) levering,

Les extrémités du support de la denture sont échancrés (11 fig 1 & 3) The ends of the toothing support are notched (11 fig 1 & 3)
s'adaptant ainsi parfaitement aux manches lors de l'emboîtage. thus adapting perfectly to the sleeves during fitting.
La solidarité de l'ensemble est assurée par 2 boulons (9)fig 1) reliant The solidarity of the whole is ensured by 2 bolts (9) fig 1) connecting

-La largeur du porte griffe peut être variable suivant le nombre de dents. -The width of the hot shoe can be variable depending on the number of teeth.
Selon une variante de la réalisation, les bras et le raidisseur peuvent According to a variant of the embodiment, the arms and the stiffener can

Selon une autre variante non illustrée cet outil peut être aussi éxécuté According to another variant not illustrated, this tool can also be executed
en 1 seule pièce avec denture fixe pré-déterminée. in one piece with pre-determined fixed toothing.
L'outil s'utilise en station verticale et non courbée comme avec une bêche. The tool is used in a vertical station and not curved as with a spade.
Il se positionne à bouts de bras,s'enfonce par une légère pression sur le poussoir (8) situé au milieu Jusqu'au buttoir. L'écartement des manches et la forme du raidisseur permettent de le tirer vers sa en ramenant le ranches It is positioned at arm's length, sinks with a slight pressure on the pusher (8) located in the middle Up to the buttress. The spacing of the sleeves and the shape of the stiffener allow it to be pulled towards its by bringing back the ranches

La finesse des dents permet l'emiettement de la motte et si la terre est lourde, il suffit d'effectuer un léger pivotement alternativement sur chaque manche pour disloquer la terre.Pendant toute la durée de la manoeuvre, l'opérateur ne s'est jamais penché ni n'a eu besoin d'agir sur son dos - l'effort étant transféré sur les bras grâce à la forme et à la longueur des manches -. La largeur de l'outil et l'espacement des dents de la griffe permettent une exécution du the full width of the root ball. The fineness of the teeth allows the crumbling of the root ball and if the soil is heavy, it is enough to carry out a slight pivoting alternately on each handle to dislocate the earth. During the whole duration of the maneuver, the operator never bent or needed to act on his back - the effort being transferred to the arms thanks to the shape and length of the sleeves -. The width of the tool and the spacing of the claw teeth allow execution of the
