A user interface for a snow groomer or other tracked vehicle, such as tracked carrier to carry and enable use of work equipment on various terrains, is provided. The user interface may comprise an input device, an output device and a controller. The controller is configured to receive from the input device an indication of a desired snow grooming distance, and the controller is further configured to measure a distance traveled by the snow groomer, and to cause the output device to convey a remaining distance to be traveled by the snow groomer, the remaining distance being the difference between the desired snow grooming distance and the distance traveled by the snow groomer.

A method for handling insulating materials used for storing snow, wherein the insulating materials covering a heap of snow stored through the summer are taken off the heap of snow before the snow in the heap of snow is transferred to a selected use. In the method, the insulating materials used for covering the heap of snow stored through the summer are transferred to such another use, in which the insulating materials have at least one function other than mere storage of the insulating materials.
