Abstract

APPAREIL ARATOIRE COMPORTANT AU MOINS UN OUTIL DE TRAVAIL SOLIDAIRE D'UN AGE MONTE PIVOTANT ET MAINTENU PAR L'INTERMEDIAIRE D'UN TIRANT DONT LA LONGUEUR EST SUPERIEURE A CELLE DUDIT AGE ET QUI EST ARTICULE AUDIT CHASSIS PAR SON EXTREMITE AVANT, TANDIS QU'ENTRE L'EXTREMITE ARRIERE DUDIT TIRANT ET L'EXTREMITE ARRIERE DUDIT AGE EST PREVUE UNE LIAISON EXERCANT UNE PRESSION SUR LEDIT OUTIL POUR LE MAINTENIR EN POSITION DE TRAVAIL. SELON L'INVENTION, CET APPAREIL EST CARACTERISE EN CE QUE LADITE LIAISON EST FORMEE PAR AU MOINS UN JEU DE BIELLETTES ARTICULEE, FORMANT GENOUILLERE, LESDITES BIELLETTES ETANT MAINTENUES EN EXTENSION PAR UN MOYEN DE PUISSANCE SENSIBLEMENT EN PROLONGEMENT L'UNE DE L'AUTRE DANS UNE POSITION PROCHE DE L'HORIZONTALE LORQUE L'OUTIL EST EN POSITION DE TRAVAIL ET POUVANT PRENDRE UNE POSITION BRISEE, A L'ENCONTRE DE L'ACTION DUDIT MOYEN DE PUISSANCE, LORSQUE LEDIT OUTIL S'EFFACE DEVANT UN OBSTACLE. CHARRUE REVERSIBLE.
