Snowgroomer and method for controlling a snowgroomer

A snow groomer vehicle comprising:

• a frame (2) extending along a longitudinal axis (70);
• a tiller assembly (9) connected to the frame (2) by a connecting device (21), the tiller assembly (9) comprising at least a tiller (9a) and a finisher (9b);
• at least one control device (17) coupled to the tiller assembly (9) and configured to control at least two parameters of the tiller assembly (9), the at least two parameters selected from a group consisting of parameters of the tiller assembly (9):
• speed and/or direction of rotation of a shaft (9d);
• depth and/or cutting angle of the tiller (9a);
• position of the tiller assembly (9a) along a vertical axis (71);
• and
• a mode for adjusting the position of the tiller assembly (9) along the vertical axis (71), selected from:
• a mode wherein the tiller assembly (9) is in a fixed position,
• a mode wherein the tiller assembly (9) exerts a certain pressure on the snowpack (72) in addition to the tiller assembly's own weight or by subtraction from the tiller assembly's own weight and said pressure value exerted, and
• a mode wherein the tiller assembly (9) is in a floating position, and the floating position follows the snowpack (72);
• position of wings (9e) open or closed;
• volume of a working chamber of the tiller (9a);
• position of the tiller (9a) in relation to a horizontal plane (73);
• mode of adjustment of the position of the tiller (9a) in relation to the horizontal plane (73) wherein the mode of adjustment is between a mode wherein the tiller assembly (9) is in the fixed position, and a mode wherein the tiller assembly is in a floating position;
• and
• position of the finisher (9b);
• the control device (17) includes a memory (19) configured to store at least two groups of values (N, M), relating to the at least two parameters, wherein each group of values (N, M) includes at least one value for each of the at least two parameters;
• the control device (17) being configured to receive a selection of a group of values of the at least two groups of values (N, M) and control the at least two parameters of the tiller assembly (9) according to the values of the selected group of values (N;
• M).
