- Model 111 AA and 111 AA-R - Vine Leaf Stripper


A revolutionary machine that can strip the vine leaves also when the grape is fully formed with a delicacy hitherto reserved only to hand work. A revolutionary machine, extreme evolution of pull stripper machines, used to perform this delicate and dangerous operation not only in the very early stages of heat when the fruit is fully formed with a delicacy hitherto reserved only to the operation conducted manually.

The long experience gained in twenty years (first Italian company to offer for sale vineyard strippers in 1994) made it possible to develop a leaf stripper where the goal was to expand as much as possible to the time window used in the absence of damage to fruit. This objective was successfully achieved through a patented control system of the position of roll from stripping vegetation and fruits.

The working head automatically moves towards the vegetation until the screen-sensor is in contact with the vegetation and the same screen is pressed until the “zero point”, beyond which the movement of the work head is inverted so that away from vegetation. This system allows you to “copy” the profile of the vegetation following it accurately and automatically removing the operator with the difficult task of maintaining the correct distance from the head of the vegetation, in the absence of which there is insufficient if the stripping away excessive damage to fruit if the head is positioned too far into the vegetation. In the presence of only vegetation the movement of the head is at reduced speed while in presence of obstacles such as poles or more resistant grape the movement versus the center of the row goes at higher speeds, allowing ecpeptional repect of the fruit, which has been verified in a functional test carried out CNR-Imamoter in the experimental fields of their fields in Vezzolano.

Another feature unique and patented on this machine is the ability to adjust the intensity of leaf stripping setting by push button, the number of revolutions of the roller stripping and changing in real time with the press of the + or – buttons on the joy-stick. The amount of leaves removed changes in a manner proportional to the rotation of the roller itself and can therefore be adjusted carefully with the direct visual control of the operator.

The machine is also equipped with the function of reversing the direction of the rollers supplied, useful to expel any debris that slipping between the rollers ripping prevent it from functioning properly. The operation can be carried out by the operator by simply pressing the dedicated button for an instant without having to stop the tractor, releasing the button resumes the regular function of leaf removal.

The machine is available in 2 versions:

  • right side version – Mod. 111 AA
  • reversible version that can operate on both sides of the tractor – Mod. 111 AA-R
