1. A snow grooming rotary snow tiller comprising: a frame;a shaft supported by said frame, said shaft configured to rotate with respect to the frame about a first axis crosswise to a direction that the frame is configured to travel along a ski slope, said shaft fitted with a plurality of tools, each tool extending along an axis for said tool which is crosswise to the first axis, each tool being selectively adjustable about the axis for said tool with respect to the first axis; andan actuating device configured to simultaneously tilt at least two of the tools about the axis for said tool with respect to the first axis. 2. The snow grooming rotary snow tiller of claim 1, wherein the actuating device includes a hydraulic circuit configured to simultaneously remote tilt the at least two tools. 3. The snow grooming rotary snow tiller of claim 1, wherein the actuating device includes a control assembly and a hydraulic circuit configured to simultaneously tilt the at least two tools from a remote position. 4. The snow grooming rotary snow tiller of claim 3, wherein the control assembly includes: a sensor configured to determine an orientation of the tools; anda control unit which includes a control panel, said control unit configured to: receive: (i) a plurality of signals related to the actual orientation of the tools from the sensor, and (ii) a plurality of signals related to a desired orientation of the tools from the control panel,compare the signals related to the actual orientation with the signals related to the desired orientation; andemit a correction signal to activate a solenoid valve of the hydraulic circuit when the signals related to the actual orientation differ from the signals related to the desired orientation. 5. The snow grooming rotary snow tiller of claim 1, wherein the actuating device includes: an actuating member configured to rotate about the first axis together with a cylinder, and configured to slide along the first axis with respect to the cylinder, anda plurality of connecting connectors, each connected to the actuating member and to a different one of the tools. 6. The snow grooming rotary snow tiller of claim 5, wherein each connecting connector includes a pin that extends along the axis for the respective one of the tools and has a portion with a plurality of axial teeth configured to engage a toothed straight portion of the actuating member to rotate the pin and the respective one of the tools as a function of a translation of the actuating member. 7. The snow grooming rotary snow tiller of claim 5, wherein the actuating device includes a linear actuator connected to the actuating member and configured to rotate, together with the shaft, about the first axis. 8. The snow grooming rotary snow tiller of claim 7, wherein the linear actuator includes a double-acting hydraulic actuator. 9. The snow grooming rotary snow tiller of claim 8, which includes a rotary distributor configured to supply the linear actuator located on the shaft. 10. The snow grooming rotary snow tiller of claim 9, wherein the linear actuator includes a cylinder integral with a shaft and a piston integral with the actuating member. 11. The snow grooming rotary snow tiller of claim 1, wherein the shaft includes a cylinder including a plurality of seats, each of the tools is rotary fitted inside a respective one of the seats and each of the tools is connected to the actuating device. 12. The snow grooming rotary snow tiller of claim 1, wherein for each tool, the axis for said tool extends radially with respect to the first axis. 13. The snow grooming rotary snow tiller of claim 1, wherein each tool includes a cylindrical portion housed inside a respective seat. 14. The snow grooming rotary snow tiller of claim 1, wherein each tool includes a cutter portion. 15. The snow grooming rotary snow tiller of claim 1, wherein each of the tools is equally oriented about the axis for said tool. 16. The snow grooming rotary snow tiller of claim 1, wherein the tools are divided into at least two groups: each group includes a plurality of the tools which are equally oriented about the axis for said tool with a different orientation from that of the plurality of the tools in the other group. 17. The snow grooming rotary snow tiller of claim 14, wherein each tool is selectively tiltable to one of: a cutting position and a paddling position.
