Abstract: The invention relates to a vegetable cutting machine and cutting method obtained with said machine, such as those used in trimming and/or chopping of vegetables, the vegetables being moved forward longitudinally aligned on tracks of conveyor belts (3 and 5) of said machine. A group of cutting heads (1) using a high pressure water jet is disposed on the conveyor (3). Each track has its won cutting head (1). A linear TV camera (6) is paced in front of said group of cutting heads (1), said camera scanning the width and length of the vegetables and the separation between them. By means of the corresponding electronic devices, it commands the motors (1.8) of the cutting heads and a motor (3.1) pertaining to the conveyor (3) so that the high pressure water jet of each cutting head (1) trims the vegetable, if required, and cuts the vegetable into a whole number of equal pieces, the size of said pieces being the closest possible to a target size.
