US Patent 11987161 Snowmobile assistant device

A wheeled device for increasing the mobility of a snowmobile or ski-bound vehicle, wherein the wheeled device, having a cylindrical axle, is attached to the bolt on the interior of a sled ski underneath the snowmobile sled, which raises the skis off the ground and does not increase the snowmobile sled width. The wheeled device surrounds the interior sled ski bolts and nuts thereon and is tightened onto said bolts and nuts by way of a tightening wheel. The snowmobile is thus able to drive on the wheeled devices so that it can conveniently move from one location to another without damaging the bottom of the skis if on rough or unstable terrain.
