Abstract: A portable electric tool, such as, for example, shears or secateurs suitable for pruning and/or harvesting work, comprises at least one moving working component disposed at the front and of a hollow frame one part of which forms the handle of the tool and inside which are housed an electric motor and a speed reducer. The outlet of the speed reducer is connected to the moving working component by means of a transmission system which comprises a moving gear unit. The tool also includes a trigger which protrudes outside the frame and operates an electric control device. The trigger and the electric control device are connected to the moving gear unit of the moving working component and follow the movements of the component. The trigger and the control device can occupy different relative positions, so that each movement made by the trigger from a neutral position, activates the control device, which in turn starts the electric motor to move the whole unit: i.e.

Abstract: A machine for training plants to be supported between two lifting wires positioned one to each side of a row of such plants. The machine includes a head comprising first and second lifting means for raising from ground level the aforesaid lifting wires and plant vegetation to be supported therebetween, first and second guide means positioned behind the lifting means in the intended direction of travel of the machine for guiding and drawing together the raised lifting wires, and connection means positioned behind the guiding means in the intended direction of travel of the machine for interconnecting the raised lifting wires. The arrangement is such that, in operation of the machine, the said first lifting means and said first guide means are positioned on one side of said row of plants and said second lifting means and said second guide means are positioned on the other side of said row of plants.
