Abstract: A telescopic extensible rod, suited to be used as extension in agricultural pneumatic tools for picking fruit from trees or of cutting off branches of trees, is formed by two coaxial tubular elements, i.e. a first tubular element and a second tubular element that slides inside the first tubular element. A pneumatic actuator can be connected to the free end of the second tubular element. A coupling is mounted between the tubular elements to removably lock their reciprocal sliding. Two coaxial pipes, a first pipe and a second pipe, are located inside the tubular elements, the second pipe being designed to slide inside the first one while keeping the seal because of the presence of a sleeve mounted between the pipes and inside the first pipe. The free ends of the pipes are in fluid-dynamic connection respectively with a compressed fluid delivery and with the pneumatic actuator.

Abstract: A tool for olive-picking, includes a rod bearing, at one of its ends, a handle with which a lever is associated, for controlling a pneumatic actuator located at an opposite end of the rod. The actuator swings a comb provided with tines, each of them being made up of two sections having a thicker and a thinner diameter respectively. Each tine is coated with a sheath of elastic and yielding material, which prevents olives from being damaged during the picking, that is carried out by inserting the comb among the branches first, and then by the subsequent swinging, controlled by the actuator.

Abstract: A system for the disinfection of prune branches or vines shoots includes a pair of shears having blades hinged by a pin. A specially shaped thin blade is fastened to the pin for holding a nozzle located on the cutting edge of the cutting blades. Disinfectant liquid is contained under pressure in a tank and is delivered to the nozzle through a valve attached to the body of the shears and actuated by a lever that also controls operation of the shear blades. Pressurized liquid disinfectant is delivered concurrently with the shearing action of the blades. All components for disinfectant delivery are external to the shear body and blades and detachable therefrom.
