Abstract: A snow groomer has a first and second track; an internal combustion engine; a plurality of working devices; a user interface; a power transmission; a first computing block for determining a total power demand of the working devices; and a second computing block for determining a work point in a characteristic graph of the internal combustion engine as a function of total power demand and the fuel consumption of the internal combustion engine.

Abstract: A hitch device for connecting a groomer vehicle having a first frame extending along a first axis, and an implement, in particular a rotary snow tiller, for grooming the snow covering of ski slopes and having a second frame extending crosswise to and symmetrically with respect to a second axis. The hitch device has an arm hinged to the first frame about a third axis perpendicular to the first axis, and about a fourth axis perpendicular to the first and third axis; a first actuator for adjusting the position of the arm about the third axis with respect to the first frame to lift and lower the implement; at least one second actuator for adjusting the position of the arm about the fourth axis with respect to the first frame; a movable coupling movable between the arm and one of the first and second frame; and a third actuator for adjusting the position of the arm in a plane crosswise to the fourth axis.

Abstract: A ski slope snow groomer having a frame; two wheel assemblies on opposite sides of the frame; two tracks wound respectively about the two wheel assemblies; a variable-configuration shock absorber assembly connected to the wheel assemblies and the frame and configured to adjust the wheel assemblies; and a control assembly configured to acquire a signal indicating an operating state of the snow groomer, and to adjust the shock absorber assembly as a function of the operating state signal.
