Abstract

a. Dispositif de commande pour l'équipement de levage hydraulique de tracteurs agricoles ou analogues. b. Dispositif caractérisé en ce que les branches de transmission de grandeurs de commande 26, 50, 53 des indicateurs de valeur reelle de résistance à la traction 8 et/ou de position ainsi que de position de vérin 28 sont reliées par un dispositif convertisseur 11 à 14 de valeur d'impulsion commune avec un dispositif 16 à 22, 23, 32 à 35 de reglage de l'appareillage de commande 63. c. L'invention s'applique à la conduite des tracteurs agricoles.at. Control device for the hydraulic lifting equipment of agricultural tractors or the like. b. Device characterized in that the branches for transmitting control quantities 26, 50, 53 of the indicators of actual value of tensile strength 8 and / or of position as well as of cylinder position 28 are connected by a converter device 11 to 14 of pulse value common with a device 16 to 22, 23, 32 to 35 for adjusting the control equipment 63. c. The invention applies to the driving of agricultural tractors.
