Tractor comprising: - a driving area for housing a user, comprising a screen; - a movement system; - a vision system comprising: i) a detection group comprising at least one camera suitable to observe a predefined region proximal to the tractor; ii) an analysis group, suitable to process and analyse the images acquired by the detection group, to verify the presence of a stationary or moving (S') subject in the predefined region; iii) a signalling group suitable to signal to the user what is detected by the detection group and verified by the analysis group by means of: a processed video signal on the screen that displays the predefined region and the stationary or moving (S') subject detected; and/or an acoustic signal; the tractor being characterized by a control group operatively connected to the movement system to command the stationing of the tractor, or a predefined movement of the tractor or the stopping of the tractor in a situation in which the analysis group detects the presence of a stationary subject or moving subject (S') in the predefined region; whereby the moving system comprises a continuous transmission group and the control group is operatively connected to the continuous transmission group to command a predefined transmission ratio. - a driving area for housing a user, comprising a screen; - a movement system; - a vision system comprising: i) a detection group comprising at least one camera suitable to observe a predefined region proximal to the tractor; ii) an analysis group, suitable to process and analyse the images acquired by the detection group, to verify the presence of a stationary or moving (S') subject in the predefined region; iii) a signalling group suitable to signal to the user what is detected by the detection group and verified by the analysis group by means of: a processed video signal on the screen that displays the predefined region and the stationary or moving (S') subject detected; and/or an acoustic signal; the tractor being characterized by a control group operatively connected to the movement system to command the stationing of the tractor, or a predefined movement of the tractor or the stopping of the tractor in a situation in which the analysis group detects the presence of a stationary subject or moving subject (S') in the predefined region; whereby the moving system comprises a continuous transmission group and the control group is operatively connected to the continuous transmission group to command a predefined transmission ratio. i) a detection group comprising at least one camera suitable to observe a predefined region proximal to the tractor; ii) an analysis group, suitable to process and analyse the images acquired by the detection group, to verify the presence of a stationary or moving (S') subject in the predefined region; iii) a signalling group suitable to signal to the user what is detected by the detection group and verified by the analysis group by means of: a processed video signal on the screen that displays the predefined region and the stationary or moving (S') subject detected; and/or an acoustic signal; the tractor being characterized by a control group operatively connected to the movement system to command the stationing of the tractor, or a predefined movement of the tractor or the stopping of the tractor in a situation in which the analysis group detects the presence of a stationary subject or moving subject (S') in the predefined region; whereby the moving system comprises a continuous transmission group and the control group is operatively connected to the continuous transmission group to command a predefined transmission ratio. a processed video signal on the screen that displays the predefined region and the stationary or moving (S') subject detected; and/or an acoustic signal; the tractor being characterized by a control group operatively connected to the movement system to command the stationing of the tractor, or a predefined movement of the tractor or the stopping of the tractor in a situation in which the analysis group detects the presence of a stationary subject or moving subject (S') in the predefined region; whereby the moving system comprises a continuous transmission group and the control group is operatively connected to the continuous transmission group to command a predefined transmission ratio.
