Abstract
(EN) An agricultural vehicle with a working unit for performing an agricultural task, and with a chassis comprising a front wheelset which is rotatable with respect to the chassis about a first vertical rotational axis, and a rear wheelset which is rotatable with respect to the chassis about a second vertical rotational axis, wherein each wheelset comprises a rigid arm with a drivable wheel at both ends, a controller for independent control of the rotation speed of each wheel and configured for placing the agricultural vehicle in a normal position and in a crab-steer position by means of separate driving of the wheels, wherein in the normal position, the rotational axes of the wheels stand perpendicularly to the longitudinal axis of the chassis, and wherein in the crab-steer position, the rotational axes of the wheels stand at an angle to the longitudinal axis of the chassis.
(FR) L'invention concerne un véhicule agricole ayant une unité de travail servant à effectuer une tâche agricole, et un châssis comprenant un train de roues avant qui peut tourner par rapport au châssis autour d'un premier axe de rotation vertical, et un train de roues arrière qui peut tourner par rapport au châssis autour d'un deuxième axe de rotation vertical, chaque train de roues comprenant un bras rigide avec une roue pouvant être entraînée aux deux extrémités, un dispositif de commande pour une commande indépendante de la vitesse de rotation de chaque roue et configuré pour placer le véhicule agricole dans une position normale et dans une position de marche en crabe au moyen de l'entraînement séparé des roues, dans la position normale, les axes de rotation des roues se trouvant de manière perpendiculaire par rapport à l'axe longitudinal du châssis, et, dans la position de marche en crabe, les axes de rotation des roues se trouvant selon un angle par rapport à l'axe longitudinal du châssis.
