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 device attachable to a pair of cross-country skis for grooming a trail in fresh snow simply by skiing the first pass. The purpose of this invention is to create a grooved trail in fresh snow to guide all skiers that follow in the same track. Without this attachment installed on the lead skier's ski, the soft snow on each side of the packed ski track does not help to keep the subsequent skier's ski in the lead skier's track. For them, it is like trying to ski on top of a narrow rail. This creates a situation where the skier must be diligent to stay in the track. With this device installed on the lead skiers ski, the subsequent skiers are guided by the packed snow on the sides of the lead skier's ski track. When skiing in tracks made using this invention, a skier can ski faster and smoother than in untracked snow. Since the compacted track helps guide the skier in the track, it allows the skier to focus on, and enjoy, the surroundings scenery. Another unique characteristic of this invention is its 2-part construction that allows the trail-making portion of the invention to be added and/or removed at any time. This allows the skier to easily change from being the lead skier to being a following skier. Or, if skiing alone, to return without the trail-making attachment, along the track he or she previously made.
