Abstract: A lifting and steering device for a steering wheel of a vehicle comprising a main fixed tubular body, a second tube, a wheel support fixed rigidly to said second tube, a shaft mounted for rotation in the upper closed end of said tubular body, a first coupling means for coupling the upper end of said shaft to a steering control, a second coupling means for coupling said tube to said shaft so as to interlock them for rotation while allowing axial movement therebetween, and a hydraulic actuator for moving said second tube axially with respect to said shaft. The actuator is disposed inside said tube and one of the two elements of the actuator, namely its cylinder or its piston rod, is coupled to the tube whereas the other element of the actuator is coupled to said shaft.

Abstract: A device for harvesting fruits or berries, particularly grapes, for in-line crops is of the type formed by a vehicle on which are rotatably mounted "hedgehog" drums with fingers or whips penetrating into the vegetation and dislodging the fruits. The drums are subdivided into superimposed coaxial elements each comprising a hub fixed on a vertical drive shaft and forming a variable angle with this latter and sleeves mounted freely rotatable on these hubs and also sloping by the same angle, these hubs carrying fingers and a support for rotatably driven vibrating inertia blocks. This device causes vibration of said fingers, which is adjustable by adjusting the rotational speed of the shaft, by varying the angle and the clearance of the inertia blocks, which vibration is the resultant of the vertical component and a horizontal component adjustable independently of each other.
