A snow grooming vehicle for refining ski slopes; the snow grooming vehicle including: a main frame to laterally support tracks and a cab at the top; a support frame coupled to the front or to rear of the main frame; a working assembly configured for refining the surface. A pre-existing coupling interface is provided between the support frame and the working assembly, formed by corresponding portions of the support frame and the working assembly configured to enable the selective coupling of the working assembly with the support frame. The snow grooming vehicle further includes a quick-coupling assembly at the pre-existing coupling interface between the support frame and the working assembly to selectively couple the working assembly with the support frame, so that the coupling between the support frame and the working assembly is no longer direct but mediated by the quick-coupling assembly, which forms a new coupling interface.

A snow groomer vehicle includes an implement such as a blade and a tiller assembly, a first detection device configured to define data by processing areas of an environment behind the snow groomer; a satellite navigation device and/or a second detection device to define data by processing the areas of the environment in front of the snow groomer vehicle and framed by the second detection device; and a control system including a processing unit to process data from the satellite navigation device and/or the second detection device to define an objective map of a desired snow treatment. The processing unit defines a first desired implement configuration based on the objective map, determines a second optimal implement configuration based on the first desired configuration and a defined snow quality value. The processing unit further displays information, or operates, or makes the implement work based on the second determined optimal configuration.

The blade comprises: a body portion; and an edge portion, the edge portion defining an edge of the blade and being secured adhesively to the body part. The body portion can be defined by a relatively low density material and the edge portion can be defined by a relatively high density material. The body portion and edge portion can each be defined by a respective metal, the metals of the body portion and edge portion being dissimilar. The adhesive can be a two-part methacrylate structural adhesive. The body portion can be 6061 aluminum and the edge portion can be 440C stainless.

A snow tiller for preparing ski piste has a frame configured to be coupled to a crawler vehicle and advanced in a forward direction; at least one rotor rotatably supported around an axis of rotation by the frame; an electric motor driving the rotor; and a plurality of linear actuators of control, each of which is a DC electric actuator or a hydraulic actuator driven by a hydraulic pump and a hydraulic circuit mounted on board the snow tiller, the hydraulic pump being driven by an additional electric motor mounted on board the snow tiller or by the electric motor driving the rotor.

Snow groomer with a propulsion system in which an endothermic engine is accommodated in an engine compartment adjacent to the cabin and provided with a liquid cooling system provided with a radiator coupled to a fan configured to suck an air flow into the engine compartment. An electronic control unit controls the on/off cycle of the fan based on a signal T.sub.Water that is a function of the measured temperature of the cooling liquid in the radiator and a reference signal T.sub.Water_ref representing a target temperature. The control unit processes a further control signal Tc relating to the amount of the heat flow from the engine to the cabin and compares the control signal Tc with a reference signal Tcref to control the start-up of the fan to generate the intake of air at room temperature into the engine compartment and the expulsion of hot air from the engine compartment.
